Title: Method and mechanism for interactively governing trigger movement and regulating the cyclic firing rate of firearms

Description:
The present applications claims priority to the earlier filed provisional application having Ser. No. 62/346,289 and hereby incorporates subject matter of the provisional application in its entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to firearms and more distinctly to an interfacing apparatus and operational method which governs the interaction between the firearms trigger, the operators trigger finger, and the innermost region of the operators firing hand thereby regulating trigger movement and the related discharge of ammunition. 
     2. Description of Related Prior Art 
     There have been multifarious types of devices and methods developed in the field of firearms in order to govern the discharge of ammunition which have been generally created in order to initiate a single discharge event or increase the firing rate of firearms especially for semiautomatic firearms, including simple methods such as the commonly known bump firing technique. 
     Although the present useful invention is intended in its utility to be a uniquely novel method and mechanism which enables the firearm operator to apply and control variable incremental trigger movement and/or isometrically variable trigger finger pressure upon the firearm trigger, while offering a distinctive and unique means and mechanism with which to govern a diversity of ammunition discharge events ranging from a single discharge event to a sequential and/or variable cyclic firing rate for firearms, and which utilize an interfacing controlling mechanism and/or adjustably locatable modules in order to delineate and/or interact with the firearms trigger discharge and/or trigger reset points inter-operatively, the forthcoming referenced exemplary devices may be representative in approximate utility and constitute a selection of the prior art having the nearest illustrative and sample comparisons available. 
     The following examples of prior art were developed in consideration of, and focus primarily around, the expressed utility of increasing the firing rate of semiautomatic firearms and have been structured with the utilization of various ancillary mechanisms including certain prior art configurations involving designated primary firing units and other secondary supporting type elements. The comparative prior art may also include various structures which are engaged with and/or around the firearms trigger guard and/or trigger with ranging elements that incorporate the use of various paddles, screws, rods, springs, and housings among other diverse ancillary parts and mechanisms. 
     An example of the type of prior art associated with a trigger and/or trigger housing device designed to rapidly increase the firing rate of firearms is presented in U.S. Pat. No. 6,164,002 issued to Troncoso on Dec. 26, 2000, titled “GUN HAVING A RAPID FIRE TRIGGER ASSEMBLY AND THE ASSEMBLY THEREFOR ” hereafter referred to as Troncoso &#39;002. The prior art is described therein as a rapid fire trigger assembly. The prior art apparatus generally affixes detachably to the trigger housing and utilizes a coil type compression spring to effect a constant forward biasing of the trigger. An expressed lever projects upwardly within the trigger housing and forwardly of the trigger and, with the incorporation of other structural parts of the device, moves the trigger rearward when the projecting lever is manually pivoted forwardly thereby causing the trigger to fire the gun. As illustratively expressed in the Troncoso &#39;002 prior art, the constant coil spring type forward biasing of the trigger and the associated mechanism effectively resets the trigger after the discharge event while a concurrent ongoing forward pressure exerted upon the expressed upward protruding lever, applied by the trigger finger, initiates another cyclic discharge event. This forward pivoting of what amounts to a manually engaged secondary type trigger within the original trigger housing is antithetical to the normal method that shooters use to discharge a firearm, and the above described prior art structural spring and trigger biasing mechanism and apparatus having a secondary type trigger mechanism is somewhat operationally awkward and problematic, especially when examined in consideration of the subsequent narrative and when reviewed in further comparison to the following referenced prior art and the present novel invention. 
     Other innovative prior art contrivances designed to increase the firing rate of semiautomatic firearms have incorporated so called primary “firing units” and/or secondary “supporting units” consisting of elements which interface in a transverse back-and-forth relationship. For example, U.S. Pat. No. 6,101,918 issued to Akins on Aug. 15, 2000 titled “METHOD AND APPARATUS FOR ACCELERATING THE CYCLIC FIRING RATE OF A SEMI-AUTOMATIC FIREARM ” hereinafter simply referred to as the Akins &#39;918. 
     The Akins &#39;918 prior art expresses an exemplary firearm which has a trigger, barrel, and receiver inclusively defined as one structural primary element and/or firing unit that generally glides and/or slides back-and-forth transversely upon structural supporting rods and related elements, the firing unit being continuously biased forwardly by compression type springs while supported by a secondary structural element and/or supporting unit. As described therein the prior art secondary supporting apparatus encompasses a stock and handle and a trigger finger locating device and/or trigger finger “stop” or rest being located on the opposite side of the trigger from the trigger finger and which effectively acts as a fixed placement and stationary rest for the firearm users trigger finger. 
     In operational use the Akins &#39;918 prior art requires that the shooters trigger finger be placed in front of and across the front of the trigger of the firing unit and fixedly onto the trigger finger stop of the secondary supporting unit. The firing unit including the trigger is constantly biased forwardly by compression springs. The forwardly biased trigger is thereafter depressed rearwards by the users trigger finger as the trigger finger is coincidentally placed rearwards fixedly on the trigger finger stop and/or locating device, thereby isolating the rearward movement of the trigger finger to a fixed position that coincides with the firearm trigger discharge locational position. In utility the firearm operator locates the trigger finger, while in contact with the trigger, to a fixed position upon the trigger finger stop and thereby initiates a coinciding primary discharge of ammunition. As the initial discharge event occurs a coinciding recoil force is generated upon the firing unit and the trigger then translates itself rearward as a part of the transversely reciprocating primary firing unit structure. During the recoil event, which effectively generates a temporary rearward movement of the firing unit, the fixed trigger finger remains stationary, having been placed across the front of the trigger and onto the trigger finger stop. This interaction thereby effects a complete and total disengagement of any physical contact between the trigger and the stationary trigger finger, as mandated in the Akins &#39;918 prior art. As the recoil force generated from the initial discharge event subsides the primary firing unit, being continuously and forwardly biased by the elemental compression springs, overcomes the kinetic force of the recoil effect upon the firing unit of the firearm and by that means effectively moves the firing unit transversely forward towards its original position and effectively thereby reengages the trigger by physically interfacing the trigger with the fixed, isolated, and stationary trigger finger. The transverse back-and-forth interaction between the primary firing unit and the supporting elements of the firearm generate a following sequential discharged of ammunition and the firing cycle repeats itself until the trigger finger is removed from its stationary position and/or the firearm runs out of ammunition. 
     Although the Akins &#39;918 system proved effective in its utility and was apparently first approved by the proper agency of the United States Bureau of Alcohol, Tobacco, and Firearms (BATF), it was later scrutinized by the BATF in evident disapprobation. The Akins &#39;918 prior art, utilizing a spring based forward biasing of the firing unit and automatically thereby interfacing the moving trigger against the fixed and stationary trigger finger, being depressed only one time against the trigger finger stop in order to initiate and sustain a rapid firing sequence, was apparently reviewed and interpreted by the BATF during that period of time as being somewhat similar in function to a fully automatic firearm described below. In addition it has been suggested that the original design and expression of the Akins &#39;918 apparatus, as it was first submitted to and then approved by the BATF, was later apparently altered somewhat significantly between the time it was submitted to the BATF and the actual time it became commercially available. 
     The legal definition of a fully automatic firearm as determined under the National Firearms Act (NFA) and in particular the NFA, 26 U.S.C. §5845(b) rule and/or statute, defines a “machine-gun” as “ . . . any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger.” A well publicized recall of the Akins &#39;918 prior art forwardly biasing spring structure followed as the BATF rescinded its apparent former approval of the mechanism. However, it is now understood that a following and more recent modification of the Akins &#39;918 device and/or a similar designed apparatus incorporating the described prior art primary firing unit and a secondary supporting element, while utilizing manual forward biasing instead of spring based forward biasing of the primary firing unit, was conditionally approved by the BATF. It is also understood that the modified Akins &#39;918 prior art device achieves the same and/or similar rapid fire cyclic effect as did the earlier utilization of springs in the Akins &#39;918 prior art. Beyond the above issues, the Akins &#39;918 prior art system and design requires a significant number of moving and/or ancillary non Original Equipment Manufacturer (OEM) parts, including supplements involving the primary firing unit and the secondary supporting elements, which increases the cost and complexity of manufacturing and inventory control while substantively restricting the application of the Akins &#39;918 system to a relatively limited number and type of firearm. 
     Another prior art apparatus designed to increase the firing rate of firearms and which similarly incorporates a primary firing unit and a secondary supporting type element without the use of springs, was issued as U.S. Pat. No. 8,607,687 B2 to Cottle on Dec. 17, 2013 and titled “SLIDE STOCK FOR FIREARM WITH CONTOURED FINGER REST ” hereinafter referred to simply as Cottle &#39;687. The Cottle &#39;687 prior art utilizes somewhat similar elements with those of Akins &#39;918 including a primary firing unit being referred to in the Cottle &#39;687 as a “bearing element” and a secondary supporting monolithic element and which interface in a back-and-forth transverse sliding manner. The Akins &#39;918 and the Cottle &#39;687 prior art additionally incorporate similar utility by requiring a complete physical separation of the trigger finger from the trigger during operation. A notable distinction between the original Akins &#39;918 and the following Cottle &#39;687 prior art in particular being that the Cottle &#39;687 prior art mandates user induced forward physical biasing of the primary firing unit instead of the compression spring based auto-mechanical forward biasing of the primary firing unit as utilized in the original Akins &#39;918 prior art. 
     The Cottle &#39;687 prior art incorporates a monolithic supporting element designated by Cottle &#39;687 as a sliding stock or “bump stock” hereinafter referenced as a slide stock and/or bump stock which incorporates a single structurally integrated handle with contoured finger rest. The Cottle &#39;687 prior art refers in passing to the monolithic supporting secondary unit as a singular handle. In comparable utility to Akins &#39;918 the Cottle &#39;687 prior art integrate the firearms receiver, barrel, and trigger in transverse movement as a singular conjoined primary firing unit. The primary firing unit and/or “bearing element” of the Cottle &#39;687 prior art functions in a sliding back-and-forth manner and operatively thereby interface interdependently with the secondary supporting apparatus and/or so called monolithic slide-stock element and its inclusive handle and finger rest. For ease of understanding, the so called bump stock is technically described with greater detail in the following reference to the Cottle &#39;687 patent as discussed under the prior art Summary of the Invention and Advantages quote: 
     “According to an aspect of this invention, a bump-stock for a semi-automatic firearm includes a handle adapted to be grasped by a user&#39;s hand. The handle including an opposing surface for directly interacting with a bearing element of the firearm so that the handle is able to reciprocate relative to the bearing element back-and-forth along a constrained linear path. The bump-stock also includes a finger rest. The finger rest is configured to stabilize the end of a user&#39;s trigger finger in a partially extended condition so that in use the user&#39;s trigger finger stretches in front of the firearm trigger while the remaining fingers of the user&#39;s hand grasp the handle. The finger rest and the handle are fixed together as a unit for concerted back-and-forth movement along the constrained linear path. The finger rest has a concave open end establishing a cradle for the user&#39;s trigger finger while the remaining fingers of the user&#39;s rear hand grasp the handle.” . . . end of quotation. The Cottle &#39;687 prior art additionally claims to be an improvement on a well known method of rapidly cycling a firearm, methodically referred to in the Cottle &#39;687 prior art as “bump firing” and in all probability may be where the term bump stock, as referenced within the Cottle &#39;687 prior art, takes its origin. 
     In practice of the Cottle &#39;687 prior art the user and/or firearm operator grasps the handle of the bump-stock and positions the bump-stock upon the users shoulder in similar fashion to the standard operational procedure and normal shooting manner for a rifle type firearm. The user then isolates the trigger finger on the bump-stock trigger finger rest by placement thereof across the front of the trigger and onto the trigger finger rest. As expressed in the Cottle &#39;687 prior art the trigger finger rest is integrated into the handle of the monolithic bump-stock and the trigger finger rest is contoured and spatially located on the opposite side of the trigger from the forwardly extended trigger finger of the users firing hand. In other words, the contoured trigger finger rest is structurally located on the left side of the handle when used by a right handed person when viewed from the rear region of the firearm. 
     It is mandated within the Cottle &#39;687 prior art that, in order for the user to initiate a primary discharge of ammunition, the firearm operator must first stabilize the firearm by securing the butt end of the bump-stock against the users shoulder region with effective stabilizing rearward force while holding the bump-stock handle with the users firing hand. 
     The user must then stretch the trigger finger of the shooting hand across the front of the trigger and locate the trigger finger in a fixed position on the contoured trigger finger rest of the bump-stock handle. This initial placement of the trigger finger in a fixed and stationary manner upon the trigger finger rest, and the coinciding placement of the so called bump-stock against the shoulder of the firearm operator and/or user, is such that the front of the trigger is not in contact with the trigger finger until the user discharges an initial and/or a following sequential round of ammunition by physically moving and/or biasing the primary firing unit forwardly. In other words, the Cottle &#39;687 forward biasing of the firing unit element brings the trigger transversely into physical contact with the isolated trigger finger located on the contoured trigger finger rest of the handle of the bump-stock. The Cottle &#39;687 bump-stock, incorporating both the handle and contoured trigger finger rest as an integral part of the secondary supporting element, constantly remains in a relatively fixed location having the butt end of the monolithic bump-stock/shoulder stock in constant contact with the users shoulder while the firing unit “bearing element” moves transversely in a back and forth fashion. 
     Still referring to the Cottle &#39;687 prior art, in utility the mandated and user generated physical forward movement of the firing unit and the consequent interaction and resulting contact between the isolated trigger finger, being fixedly located on the monolithic bump-stock element, with the forward moving trigger as incorporated in the primary firing unit thereby initiates a first and primary discharge of ammunition. This initial discharge of ammunition generates a rearward force recoil effect and kinetic momentum upon the combined barrel, receiver, and trigger group of the firing unit and as a result moves the primary firing unit in a lateral and rearward direction and which by that means disconnects the conjoined trigger from the stationary trigger finger located on the trigger finger rest of the bump-stock. The resulting de facto physical separation of the trigger from the trigger finger, as has been previously referenced, is an essential part of the mandated utility and operational requirement of the Cottle &#39;687 and Akins &#39;918 prior art. 
     In ongoing reference to Cottle &#39;687, as the firearm operator continues to apply the mandated manual forward biasing force upon the primary firing unit that action tends to counter the recoil effect of the initial discharge event and assists in returning the primary firing unit including the incorporated trigger component forwardly in a transverse and reciprocal manner. As a consequence the bearing element is brought into repeated physical contact with the stationary isolated trigger finger, having remained located on the trigger finger rest of the monolithic bump-stock, which initiates a following sequential discharge of ammunition. If not interrupted the sequential firing pattern repeats itself in rapid order. 
     At least one inherent issue that arises from the prior art such as Akins &#39;918 and Cottle &#39;687, both of which mandate full operational separation of the trigger finger from the trigger, is lack of traditional trigger responsive interaction and/or interactive ‘trigger feel’. The standardized and normal shooting method for firearm operators utilizes responsive interaction between the operators trigger finger and the firearm trigger as an important qualitative and inherent part of the firearm shooting experience. Trigger feel and feedback is generally crucial to the shooting experience for several reasons including but not limited to both long and shorter range accuracy, varying situational firing consistency, and reliable follow up shots among many other diverse and meritorious distinctions to the prior art, including but not limited to the overall control of the firearm even, for example, when the operator is simultaneously moving and shooting. 
     As described above in the Cottle &#39;687 prior art, the utility of the interfacing primary firing unit and secondary supporting elements unfavorably mandate and deleteriously require that the operator, in order to discharge the firearm, must apparently remain in at least a minimally upright and/or stationary position with the firearm stock and/or bump stock in place against the users shoulder, while manually biasing the primary firing unit forwardly as a means to have the moving trigger collide longitudinally with the shooters fixed trigger finger as placed on the required trigger finger rest. In other words, the user is procedurally mandated by the Cottle &#39;687 prior art to simultaneously position the conjoined secondary supporting bump-stock monolithic element, including the unified handle and trigger finger rest, in a fixed location against the firearm operators shoulder. Utilizing the Cottle &#39;687 prior art shooting method while incorporating the exemplified interfacing elements could, at the least, minimally restrict and/or limit the immediate use of the firearm during a crucial period of time in which the operator may be in physical movement and/or unable to shoulder the firearm and/or while the operator may be changing firing positions, among other shooting scenarios. 
     Disadvantageously, employing the prior art to effectively discharge a rifle type firearm in a very rapid sequence from a prone position while, for example, utilizing a bipod type support to stabilize the firearm would prove, at a minimum, to be problematic and extremely difficult if not impossible depending on the circumstance. 
     Additionally, the Cottle &#39;687 prior art illustrates a lockable mechanism built into the monolithic bump stock which, when engaged or disengaged, converts the firearm from utilizing the slidable interfacing elements into a standard semiautomatic type configuration, thereby allowing the user to physically switch between the two types of firing solutions and prior art configurations. However, as mandated in the Cottle &#39;687 prior art, a lockable and unlock-able mechanical conversion from the normal and/or standard single shot per trigger pull semiautomatic function of the firearm to a more rapid cyclic firing rate of the Cottle &#39;687 prior art, disadvantageously requires that the user stop shooting and reposition the firearm and/or the users position in a way that enables the prior art device&#39;s lockable mechanism to be readably engaged or alternately disengaged by one of the users hands. After engaging and/or disengaging the lockable mechanism, being expressly located on the bottom region of the monolithic bump stock of the prior art, the operator must reposition again and then shoulder the bump stock as a means to continue using the firearm in the alternate format and according to the mandated Cottle &#39;687 prior art. 
     When reviewing real life self defense scenarios analytically, and in general terms, most situations involving firearms are basically dynamic and not static in nature, and do not frequently involve the defender standing still while shooting from a stationary position over a prolonged period of time. Generally speaking and more often as not these types of self defense scenarios involving firearms require at least some active movement on the part of the defender to help insure the safety of the defender and/or the defended. Continuous defensive firing from a standing and/or stationary position gives an armed assailant or opponent a vastly improved opportunity to acquire the defender as a target, while in contrast, a moving and/or shooting defender is much more likely to survive. Exchange of handgun fire in many documented self defense scenarios, and as commonly known by anyone familiar with the experience, typically occurs between opponents positioned within relative close proximity to each other, and these encounters are often extremely dynamic situations rather than being static in nature. An armed defender with the ability to accurately fire two or three rounds of ammunition at close range in about the same time or even less time than an armed aggressor is able to aim and accurately fire one round of ammunition, especially when engaged in a moving and shooting scenario, has a significantly enhanced tactical advantage over the aggressor along with a greatly improved chance of survival. 
     As mentioned above, the previously discussed Akins &#39;918 and Cottle &#39;687 prior art distinguishably mandate an operationally complete and required separation of the trigger finger from the surface of the trigger as an integral part of a stated and ostensible purpose for preserving the standard operational and/or normal semiautomatic status of the firearm and/or additionally allowing the trigger to reset as the trigger finger physically separates from the trigger during functional operation and utility of the prior art. As stated in Cottle &#39;687 for example, the mandated physical separation of the trigger and trigger finger during the required forward biasing of the firing unit of the embodied serviceable firearm enables the trigger mechanism to reset itself in preparation for the next sequential discharge of ammunition. 
     However, and as a general rule, most firearms require a minimal return movement of the trigger forwardly from the triggers most rearward position and/or concurrent point of ammunition discharge in order to reset the trigger mechanism and thereby preserve the normal standard operational nature of the firearm. In point of fact, a complete or even intermittent total separation of contact between the surface of the trigger and the trigger finger in order to ostensibly enable a required trigger reset event between each and every successive discharge of ammunition, such as mandated by the Akins &#39;918 and the Cottle &#39;687 prior art expressions and exemplifications, is simply not required in the vast majority of firearms. Those who are very familiar with the art will understand that supposedly requiring a complete or even intermittent total separation of contact between the surface of a trigger and the trigger finger itself in order to maintain the operating status of a semiautomatic firearm and/or to reset the trigger mechanism of the firearm in preparation for a following shot, such as is mandated by both the Akins &#39;918 and the Cottle &#39;687 prior art expressions, is not in fact an operational prerequisite or a utilitarian necessity. Moreover, the prior art in this regard, is somewhat limiting and relatively outdated while at the same time amounting to an obsolete method and means of implementation in order to accomplish the goal of quickly resetting the firearm trigger and/or maintaining the semiautomatic status of a firearm when compared to the present and novel invention as explained in greater detail below. In point of fact, regarding trigger reset devices, many of todays newer type firearms incorporate what is commonly referred to as a positive trigger reset mechanism. In typical practice these positive trigger reset devices have features that are structured to function interactively with the simultaneous movement of the trigger mechanism and hammer as it advances forwardly in order to impact the firing pin of the firearm and thereby initiate a discharge of ammunition. 
     Typically, the average trigger reset point on a standard semiautomatic firearm, and most firearms for that matter, generally lies somewhat forward of the triggers locational discharge point and somewhat rearward of the triggers most forward “at rest” and/or “ready to fire” position, and while that distance may vary somewhat it is generally specific and particular to the individual manufacturers firearm make, model, type, and individual trigger mechanism design. The fact of the matter is that the most forward trigger reset location of the typical firearm trigger is reached well before any type of physical separation of the trigger finger from the trigger is needed or required. Most importantly, the forward reset position of the trigger is reached during with the forward movement of the trigger, for example, after a discharge event and well before any type of physical separation of the trigger finger from the trigger. The normal trigger reset position is typically reached while the user still maintains an ongoing and constant contact between the trigger finger and the trigger after a normal discharge event. It is easily understood that the described interaction between the users trigger finger, maintaining a constant contact with the trigger during the trigger discharge and reset event, initiates the discharge of a single round of ammunition while continuing to maintain a single operational function of the trigger and the ongoing semi-automatic status of the firearm. 
     For the most part, standardized trigger mechanisms allow the trigger to rotate backwardly somewhat beyond the triggers locational discharge point, which is a transit typically nonessential to the discharge event. An improved expression of the prior art would actively govern, as the novel invention herein teaches, an exactingly well defined and exceedingly minimized distance between the trigger discharge and trigger reset points and to do so inter-operationally, and by that means regulate the travel distance and manage the time constants between the two points, while governing the interaction between the trigger, trigger finger, the firing hand of the operator and the trigger discharge and trigger reset points of the firearm. The novel expression of the instant invention accomplishes all of the above without the physical separation of the trigger from the trigger finger, such as is mandated by the prior art. 
     An advantageous benefit that the novel invention presents in part over the prior art is an increase in the firearms rate of fire resulting from the instant controller mechanism structure which incrementally defines the firearm trigger movement and which, when compared to the prior art, effectively delineates the essential travel distance between the trigger discharge and trigger reset points of firearms and by that means advantageously decreases the minimum time over distance interval between the trigger discharge and trigger reset events effecting thereby an increase in the cyclic rate of ammunition discharge by the firearm, especially when compared to the prior art. 
     In contrast to a standard operating semiautomatic firearm, most fully automatic firearms generally incorporate the use of what is commonly referred to as an automatic sear. The automatic sear, as a specialized part of a commonly dedicated fully automatic firearms internal trigger mechanism, helps enable multiple rounds of ammunition to be discharged in a continuous and rapid succession with a singular and constant depression of the firearms trigger, and operationally require the user to hold down the trigger with the trigger finger in a stationary and longitudinally rearward position with persistent application of rearward lateral pressure applied by the users trigger finger. When the user of the fully automatic firearm releases the volitional application of sustained pressure from the front of the trigger, and thereby allows the trigger to move forward to a certain point, the firearm immediately stops loading and discharging ammunition. The exemplary fully automatic firearm, as opposed to a standard semiautomatic firearm for example, incorporates the internal trigger mechanisms specialized automatic sear to interactively assist in discharging multiple and consecutive rounds of ammunition and by that means does not require the user to incrementally release and/or adjustably reduce the users trigger finger pressure on the trigger in order to reset the trigger mechanism in preparation for a follow up discharge of ammunition such as is required to operate a standard semiautomatic firearm. 
     By known definition semiautomatic firearms have a mechanism for self loading, but not for continual and sustained loading and sequential firing of ammunition like dedicated fully automatic firearms which incorporate the utilization of a singular and sustained trigger depression. The prior art, including other such prior art contrivances, have focused almost entirely on rapidly increasing the firing rates for semiautomatic firearms in order to achieve what might be considered somewhat similar firing rates to fully automatic firearms, and to do so while enabling the semiautomatic firearm to operate in a specific manner intended to technically maintain the semiautomatic status of the firearm. 
     An improved expression of the prior art would provide an adaptive system, method and mechanism which would allow the firearm operator to distinguishably vary the overall cyclic firing rate of semiautomatic firearms for example while enabling the operator to continually maintain a more desirable constant contact between the trigger and the trigger finger. Advantageously, the novel invention provides a more desirable and advantageous constant contact between the firing hand trigger finger and the firearm trigger while being easily employed with a significantly greater number and wider variety of firearms, not just certain configurations of only semiautomatic firearms. 
     There exists a further need for a novel interfacing apparatus that responsively functions with an increased natural interaction between the operators trigger finger, firing hand, and the firearm and which easily enables a flexible and spontaneous on the fly alteration of the firearms cyclic rate of fire, even while the operator is in physical motion and/or is changing firing positions, and which is calibrated to interface in a well defined and exacting manner with both the forward trigger reset position and/or the rearward trigger discharge position while enabling the firearm to naturally function without the need to methodically separate the trigger finger from the trigger. Additionally, the improved device should function without the the prior art requirement for the shouldering of a bump-stock. 
     As discussed above, the mandated procedural operation of both the Akins &#39;918 and Cottle &#39;687 prior art require a forward biasing of elements in order to function. As previously discussed, the original Akins &#39;918 prior art utilized compression springs for this elemental forward biasing of the designated firing unit while the Cottle &#39;687 prior art requires the elemental forward biasing to be manually effected by the incorporation of the users secondary supporting hand, the secondary supporting hand being notably other than the shooting hand and/or firing hand of the operator. 
     Another benefit that the present novel invention provides and expresses, as an improvement over the prior art, involves its advantageous utility when incorporated with the use of handguns and pistol versions of certain firearm types like, for example, the AR15 class of pistol. During the normal operation of standard semiautomatic rifle type firearms the users secondary supporting hand is placed upon the forward region of the firearm such as a forward stock, a hand guard, or a vertical type grip. In the utilization of a handgun and/or pistol class of firearm the supporting hand, when optionally employed by the operator, is typically placed upon the region of the pistol type firearm forward of the firing hand. The utilization of vertical and/or handle types of secondary ancillary forward grips on handguns have some legal issues and/or qualifiers which themselves are focused around forward handles being mounted to pistols and/or handguns. In other words, according to the rules of the BATF, it is illegal to employ vertical and/or handle type forward grips to any type of handgun and/or pistol type firearm. 
     In reference to the Cottle &#39;687 prior art, the mandatory operational procedure requires that the primary slidable firing unit or the Cottle &#39;687 so called “bearing element” is biased forwardly by the secondary supporting hand in order to engage the primary slidable trigger element with the stabilized trigger finger as placed by the user in a fixed position on a trigger finger rest being part of the secondary supporting monolithic element. Both the Akins &#39;918 prior art, which originally required a spring based and resultant mechanical forward biasing of a so called “firing unit” while utilizing a forward supporting hand on the firearm as referred to in the Akins &#39;918 prior art, or the physical forward biasing of a so called “bearing element” by a secondary supporting hand as particularly referenced in the Cottle &#39;687 prior art in order to initiate the discharge of a first round or following rounds of ammunition, require a secondary supporting hand and thereby eliminate the possibility of the firearm operator using just one hand to operate the firearm. The Cottle &#39;687 prior art makes a passing reference in narrative context and figurative diagram to a potential adaptive expression of the principal expression of Cottle &#39;687 in the utilization of a handgun and/or pistol type firearm. That expression apparently consists of a single secondary supporting element having a handle with an integral curved trigger finger rest and without the prior art bump stock but still requiring forward biasing of the firing unit, including the trigger of the firing unit, into the fixed trigger finger as it rests on the single secondary supporting unit and/or prior art handle. However, in order to utilize that particular Cottle &#39;687 prior art expression as it may apply to handguns in particular, and in order to thereby accommodate the stipulated, mandated, and required operational method and system of the Cottle &#39;687 prior art, the operator of the handgun type firearm would, out of mandated and operational necessity, be required to use both hands in order to initiate a primary discharge event and/or rapidly shoot the firearm. In other words the forward supporting hand would have to forwardly bias the handgun firing unit and/or so called bearing element into the stabilized trigger finger as it rests on the Cottle &#39;687 handle trigger finger rest structure, which monolithic handle itself is in fact also being simultaneously supported and/or held at the same time by the operators firing hand. As previously expressed and according to BATF rules the Cottle &#39;687 would not be useful when applied by a handle forwardly mounted to a handgun and/or pistol type of firearm. 
     Furthermore, a serviceman and/or civilian for example that may sustain a gunshot or other type wound or injury to the secondary supporting hand, arm, or shoulder as a result of a so called fire fight and/or other armed conflict or self defense scenario may not and/or would not be able to operate the Cottle &#39;687 or the Akins &#39;918 prior art with just one usable hand at a time. Various scenarios of real life and death self defense situations involving firearms, and whose outcome might balance on the defenders ability to quickly use one hand to operate a firearm, would certainly prove to be disadvantageous for the practical incorporation of the Cottle &#39;687 and/or the Akins &#39;918 mandated prior art utilitarian characteristics as referenced in the above discussion. An improved expression of the prior art would enable the firearm operator to use one hand to initiate a primary, secondary, and/or following discharge of ammunition, if by need or by choice. 
     Additionally, the prior art directive requiring the primary and/or firing unit be biased forwardly in order to initiate a first discharge of ammunition along with a persistent forward biasing of the primary element, in combination with ongoing stationary positioning of the secondary supporting element and/or bump-stock as a requirement to expend any following rounds of ammunition, could be improved on advantageously with a device which would not mandate intentional forward biasing to initiate a primary and/or a following secondary and/or consecutive discharge event. 
     Moreover, an improved expression over the above described prior art would easily function in utility of operation while incorporating just a minimal and/or normal requirement for the overall secondary hand support of and/or stabilization of the firearm, such as that used in the standard operational procedure for discharging firearms without the prior art. The prior art mandated requirement for the placement of the shoulder stock against the users shoulder and the additional placement of a forward supporting hand on the forward stock of a rifle type firearm in order to forwardly bias the firing unit and/or element thereby initiating a discharge and/or a following discharge of ammunition, and stabilization of the firearm with a counter bias against the recoil force and momentum of the firearm during the initial and following discharge events, should also be eliminated by an improved invention. 
     Representing a novel improvement over the prior art a beneficial expression would enable the user to intuitively operate the firearm interactively from various firing positions while simultaneously empowering the user with an improved ability to move and shoot in a simultaneous manner in accordance with the situational requirements of the individualized shooting scenario. 
     Ideally, an improved apparatus would be extremely simplified in its design and fabrication, have ease of use and application, and would function universally with a greater number and type of firearm designs. Advantageously, the apparatus should have simple operational functionality with the absolute minimum use of cams, springs, rods, screws, housings, cranks, tubes, side walls, connectors, wedges, pins, paddles, plungers, plates, blades, clamps, wires, coils, levers, moving handles, isolating finger rests and/or stops, and conjoined primary and/or secondary interactive monolithic slidable back-and-forth elements and/or the like. 
     Moreover, advantageously over the prior art, the improved device should feel and function in a more comfortable and natural manner and without the need for any mandated placement of the users trigger finger across the front of the trigger and extended onto an ancillary finger rest or finger stop in order to function the firearm. As favorably expressed below the present invention does not require or mandate trigger finger placement across the front of the trigger and onto a trigger finger rest in order to function the firearm. 
     Furthermore an innovative and improved novel mechanism and method should be reliable for versatile use in real life self defense situations which are typically dynamic and not static, and beneficially continue to be fully operable under diverse circumstances, even while the firearm itself is recoiling backwards from the momentum of the discharge event. The enhanced apparatus and method should function exceedingly well in a diverse set of circumstances, such as the above, without any of the mandated prior art requirement of incorporating a bump stock and/or placement of the bump stock stock, or in fact the use of any stock placement upon the shooters shoulder in order to fully operate the mechanism. 
     An enhanced apparatus should also be relatively inexpensive for the consumer, uncomplicated, safe and reliable, and adaptively suitable for both older and newer modern firearm designs including most types and model variations while the improved operational method would continue to remain flexibly suitable for diverse and future innovative firearm concepts. 
     An advantageously capable device would function seamlessly while not requiring that the user stop shooting then reposition the firearm to lock and/or unlock a mechanism, being located on a secondary element, in order to convert and/or alternate between the standard firing method and rapid firing method as required by and mandated in the Cottle &#39;687 prior art for example. 
     The ameliorated apparatus should also provide a natural interface between the shooters hand and the firearm handle while still closely maintaining the original functional and operational status, feel, and basic design of the Original Equipment Manufacturer (OEM) manufactured firearm. 
     An improvement over the prior art would allow the firearm operator to accurately discharge a single round of ammunition by enabling the user to move the firearm trigger in a micro-incremental and/or on the fly manner while maintaining full contact with the trigger. 
     The presently expressed innovative and novel invention addresses the limitations of the prior art with many beneficial and enhanced improvements while advantageously ensuring an inventive method of utilization which is both practical in purpose and uniquely entertaining for the average recreational shooter and the professional marksman. 
     SUMMARY OF THE INVENTION AND ADVANTAGES 
     It is therefore, accordingly, a primary objective of the instant novel invention to advantageously fulfill the foregoing needs while providing an improved innovative utility and a unique operational method and mechanism designed to functionally enable the firearm operator to accurately, intuitively, and interactively regulate the firearm trigger discharge and reset positions and by that means produce a more precise single discharge event and/or, advantageously, a variable sequential cyclic firing rate for a diversity of firearms. 
     Several inherent advantages that the current invention presents are referenced favorably below in comparative benefit and differentiation from the prior art. Although the following listed advantages represent a selection of propitious solutions to a number of previously mentioned and existing limitations of the prior art, as remarked above, there are other benefits that the immediate invention presents which will become even more obvious and apparent in view of the forthcoming supplementary information, specifications, and inclusionary documentation, thereby demonstrating the present inventions objectives to be purposeful accomplished by the various means hereinafter described. 
     The preferred apparatus, embodying stylistic illustrative concepts of the present invention, consists in its most basic structure of an interfacing controller mechanism which effects improved operational management of the firearm trigger movement. The controller in this instance having an elliptical forward region providing a variable tangential contact surface which is contiguous with the rear region of the firearms trigger, said trigger being under demonstrated proximate tension having been manually rotated laterally into contact with the controllers elliptical forward region by force of sustained rearward pressure actively applied by the operators trigger finger upon the trigger. The trigger formerly having been at rest in its normal and stationary most forward position and, while in that expressed position, out of contact with the controllers elliptical forward region. The controller structure in this expression having a most rearward conformational surface region in alignment with the innermost and/or upper-innermost region of the operators firing hand. 
     This structural arrangement and interaction provides a very natural and improved interface between the innermost and/or upper innermost region of the operators shooting hand, the trigger of the firearm, and the operators trigger finger thereby effecting a greatly enhanced trigger feel and/or trigger tactile sense, especially when compared to the prior art. The present invention additionally provides real time interactive operator engagement and a coinciding reciprocal relationship between the interfacing controller, the operators shooting hand and trigger finger, and the firearms trigger. This structural arrangement gives the firearm user greater control over a single discharge of ammunition and/or a sequential discharge event as further discussed and referenced below. 
     As referenced earlier it is also an object of the present invention to provide a unique mechanism and method that operably defines and directly interacts with the trigger reset and discharge points of the individual firearm. Accordingly, in this expression, the structure of the embodied controller incorporates adjustably locatable modular elements that define and interact operationally with both the interfacing trigger discharge locational position and the interfacing trigger reset locational position of the firearm trigger. The novel interaction is managed as an integral part and function of the presented method and mechanism, being further outlined by the teachings below and in the detailed description of the invention. 
     An additional object of the present invention is to provide an apparatus that is relatively uncomplicated and advantageously flexibly adaptive for older types of firearms and many, if not most, of the newer and more modern firearm designs while eliminating the prior art&#39;s conditional mandating of and operational requirement for a forward biasing of various elements in order to initiate a preliminary discharge event and/or a following discharge of ammunition. Furthermore, the instant invention eliminates the prior art&#39;s requirement that the operator reach out and stretch the firing hand&#39;s trigger finger across the front region of the trigger in order to place the trigger finger in a fixed position on a locator and/or trigger finger rest, the finger rest of the prior art being an integral part of a monolithic supporting element which itself is conjoined with a primary movable back-and-forth firing unit and/or element as part of an essential, integral, and thereby inherent utility of the prior art. 
     Accordingly, the present invention is extremely simplified and refined in both its utility and function and does not employ springs and/or a wide variety of ancillary parts. As previously mentioned the instant invention directly interfaces with both the operators innermost region of the firing hand and the rear region of the firearms trigger, thereby enabling direct operator contact and interaction with the firearm trigger by utilization of the trigger finger of the firing hand. This novel structural arrangement enables the trigger finger of the firearm operator to move the trigger in a normal and preferred shooting manner and in concurrence with the novel controller and the operators upper-innermost or innermost region of the firing hand, and is readily adaptive to a wide variety of firearms. The present invention does not functionally require or incorporate any conjoined primary or so called secondary supporting elements, as described above in reference to the prior art, and as a consequence thereby allows the novel expression to incorporate an increased and flexible adaptation with a greater variety of diverse firearms, requiring minimal modification thereto. Additionally, the present inventive utility empowers the operator with the ability to initialize the discharge of a primary and/or first round of ammunition without a mandated forward biasing of a monolithic firing unit, such as is required by the prior art, while giving the firearm operator enhanced trigger control over a single shot and/or a varying cyclic firing rate. Advantageously the present invention provides the user with the ability to discharge the firearm with only one hand at a time if required, and without the fundamental mandates of the prior art as referenced above. 
     Another object solution of the present invention as referenced above and expressed below is to provide a mechanism that operates without the requirement of incorporating a so called bump-stock and/or even a standard shoulder stock for a firearm and the integral placement thereof upon the shooters shoulder as part of a mandated operational firing solution such as required by the prior art. 
     Advantageously, the innovative present invention operates without the utilization of, or even need for, a shoulder stock. As referenced earlier in regard to a rifle type firearm, with the utilization of the Cottle &#39;687 prior art monolithic bump-stock for example, the rifle type firearm must be raised and shouldered by the operator in order to function the Cottle &#39;687 prior art and initiate a primary and/or following discharge of ammunition. The shoulder stock and/or so called bump stock of the Cottle &#39;687 prior art, for example, incorporates the firearm handle, a so called trigger guard, and a curved trigger finger rest as prerequisite components of a singular monolithic structure, and in simple terms requires the mandatory incorporation of these same elements by the prior art in the basic utilization of the shoulder stock and/or bump stock. The presently expressed new and novel apparatus allows the operator to utilize the immediate innovative system and method to discharge ammunition without the need to shoulder the rifle type firearm and to beneficially operate the firearm with an absolute majority and/or all of the firearm elements that structurally originate from the original manufacturer of the firearm. 
     Beneficially, the present expression easily integrates in an uncomplicated and straightforward manner with the pistol class of firearms such as, among many others, the AR15 category and other pistol types which utilize the 5.56 rifle type cartridge for example. The above pistol class the of AR15 pistol type firearms do not generally incorporate any shoulder stocks unless by special approval, classification, and/or registration under the auspices of the BATF along with a fee and/or related agency endorsement and/or with a reclassification of the pistol to that such as an SBR (Short Barreled Rifle) and/or the potential reclassification, depending on the overall changes to the firearm, under the AOW (Any Other Weapon) type alternative. This BATF classification of pistol type firearms, as discussed above, restricts the utility and minimizes the application of the prior art within the pistol class of firearms. The preferred embodiment of the present invention works within the existing structure of the above mentioned pistol class of firearms and without the need for reclassification and/or without the mandatory use of any secondary butt stock and/or bump stock and/or shoulder stock configurations and thereby does not require any special review by the BATF for any required reclassification, special review, or special registration of the original firearm and/or pistol type. 
     The instant invention as further expressed below, additionally provides a preferable system and apparatus that operates while the firearm and the firearm operator are in active concurrent movement, thereby accordingly empowering the firearm operator with the ability to safely move and shoot simultaneously if needed without having to stop and position the firearm against the operators shoulder and while additionally offering the operator a more precise, accurate, and enhanced interactive trigger control and ‘in motion’ shooting method as a combined and significant improvement over the prior art. 
     Advantageously the present invention gives the operator responsive adjustable incremental control over the amount of preferred trigger pressure and trigger movement that the operator chooses to apply as required in various shooting scenarios. The present inventions ability to precisely and incrementally govern the amount of trigger pull and interactive trigger feel, as may be required and/or optionally chosen in a particular shooting scenario, gives an increased accuracy to each individual shot and/or variable cyclic firing sequence by the utilization of balanced isometric tension between the trigger finger, trigger, and innermost region of the firing hand exerted upon the controlling mechanism, as further exemplified in the following teachings. Of course, the innovations that the novel invention advantageously presents provide certain benefits to recreational shooters, serviceman, long range competition shooting, designated marksman, law enforcement personnel, and the military sniper in theater, among others, while providing another layer of self defense protection for the everyday individual civilian. 
     Optionally, as an improvement over the prior art mentioned above, the instant expression of the removable controller may also be readily and adaptively fitted with a discretionary locking mechanism which is not illustrated in these teachings but which are easily understood by anyone familiar with the art. One locking mechanism embodiment, among many others, having a detection type system which may recognizes a unique identifier and/or other type of interfacing element being in possession of the designated operator of the firearm in order to lock and/or unlock the controller. The present inventions controller apparatus, when locked in place forwardly, will not allow the trigger mechanism to be repositioned in order to allow the trigger to reach the calibrated discharge point and as a consequence thereby the novel invention adds additional security, protection, and greater safety to the general field of firearms. 
     Beneficially, the firearm operator while in utilization of the present invention may volitionally and optionally choose to discharge a primary, secondary, and/or any following sequential discharge event over an extremely brief time period or choose to discharge the firearm over a more varied and/or moderated and governed time period advantageously over the prior art, even as the entire mass of the firearm is recoiling under momentum from a single discharge event and/or during any varying number of consecutive sequential discharge events. The innovative methodology of the present invention, beneficially over the prior art, enables the operator to continue shooting the firearm even as the firearm reacts in kind to the rearward momentum of recoil force exerted upon the body of the firearm by a discharge event and/or while the firearm is being supported in a variety of ways and a number of differing firing positions, and most favorably while the operator is in motion during changes of firing positions. In other words, the novel invention presents an improvement over the prior art in that it can be utilized in a greater number of wide ranging circumstances incorporating all types of firing positions and various moving and shooting scenarios and even as the firearm itself is continuously recoiling rearward from the force of a single discharge event or a consecutive series of discharge events which itself is, among other beneficial improvements expressed by this instant invention, a novel innovation and favorable when compared to the prior art. 
     When compared to the prior art the present invention advantageously requires only a minimal and/or a normal effort by the firearm operator in order to effect a counter-recoil stabilization of the firearm by the designated supporting hand, whether it be the forward supporting hand and/or the uppermost and or upper innermost region of the firing hand, optionally including the firing hand thumb region in the case of a one handed operation of a handgun as further discussed in the following teachings. 
     Other than a standard, natural, and minimal forward stabilization force applied to the firearm by the operator in resistance to the recoil force, the following referenced ‘firing solution sets’ advantageously do not require any enhanced forward biasing of the firearm in order to initiate either the primary discharge event or any following secondary discharge event or any successive sequence of related discharge events. However, the following discussed firing solutions generally require a nominal and/or somewhat standard stabilizing force supportively applied to the handle region of the firearm and optionally a commonly used stabilizing engagement of the operators forward supporting hand upon a hand-guard for example when exerting normal counter recoil force when operating a rifle, carbine, or other such firearm types which may require forward support in order for the firearm to function as specified by the OEM. As further expressed in these teachings, a continuing and volitionally applied isometric force exerted upon the controlling mechanism itself is integral to the utilization of the present invention when employed to discharge ammunition in a more a rapid sequence. As demonstrated and referenced below the innovative method, employing variable isometric tension as applied by the firearm operator interactively upon the novel controlling mechanism, is incorporated as a function of the relationship of the cyclic firing rate and discharge ratio of the firearm, being effectively produced as a result of the time over distance interaction between the trigger and the trigger discharge and reset points, which is governed by the following described factors and the variable isometric tension volitionally exerted upon the controller by the firearm operator. 
     As expressed and depicted below, the novel invention advantageously does not require the firearm operator to place the trigger finger across the front of the trigger and onto a secondary supporting trigger finger rest and/or element but beneficially allows the operator to interface the firing hand trigger finger directly with the trigger. Additionally seen below, the improved invention does not mandate or require the firearm operator to shoulder the firearm in order to function and in point of fact the present invention enables the firearm operator with an ability to discharge ammunition without the need to actively engage a shoulder stock in any way. 
     In other words, the improved novel invention expresses an interfacing adjustable apparatus that functions with an increased natural interaction between the operator and the firearm enabling thereby a flexible and spontaneous on the fly alteration of the firearms cyclic rate of fire and/or a single discharge event while the operator and the firearm are both stationary and/or in physical motion, and which is calibrated to interface in a well defined and exacting manner with both the forward trigger reset point and the rearward trigger discharge point while permitting the firearm to naturally function without the need to methodically separate the trigger finger from the trigger. The improved utility of the present invention beneficially governs and regulates the time and distance the trigger itself takes to travel from the trigger discharge point to the trigger reset point and back again, thereby improving the overall control of a singular discharge event and/or vary the cyclic firing rate and speed of the sequential discharge event advantageously, especially when compared to the prior art. 
     Beneficially, when utilizing the novel invention to accurately discharge a singular round of ammunition, the isometric contraction generated upon the controller mechanism by the operator is sustained until a single discharge event is initiated, for example, by the incremental relaxation of the upper-innermost hand pressure upon the rear region of the novel controlling mechanism while maintaining and/or increasing trigger finger rearward force upon the firearm trigger, and by consequence, the forward region of the controlling mechanism and thereby effectively and accurately discharging just one single round of ammunition with greater control and accuracy than that accomplished by utilizing either a standard shooting method and/or the prior art.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the invention in more detail wherein the figures have like numerals which indicate like or corresponding parts throughout the several views. 
     As seen in  FIG. 1  on drawing sheet  1 / 18 , a serviceable M4 Carbine type firearm  10  is shown schematically in a simplified semitransparent figurative depiction being diagramed in contour outline and perspective view as  FIG. 1A . 
     In more detail still referring to  FIG. 1A , as seen within  FIG. 1  on drawing sheet  1 / 18 , showing an indicating chain line encompassing in part a figurative one piece lower receiver  12  shown mounted on the M4 Carbine type firearm  10 . The figurative one piece lower receiver  12  is linked by single chain line to an enlarged semitransparent perspective view representing the same indicated one piece lower receiver  12  shown as  FIG. 1B  within the sight region of  FIG. 1  as described below. Although the illustrations within  FIG. 1  depict a unique one piece lower receiver  12 , the majority of AR15 type standard lower receivers are manufactured having a removable handle region and therefore have a two piece lower receiver which is described and further referenced below. 
     Referring now to  FIG. 1B  in perspective view as illustrated within the sight region of FIG. 1  and showing a unique one piece lower receiver  12  having an integrated handle  31  with a front region  32  and a rear region  30  having a serviceable trigger  36  encompassed by trigger housing  34 . 
     In further detail, still referring to the invention of enlarged  FIG. 1B  showing in partial phantom a removable center controller  14 , or simply controller  14  hereinafter, centrally mounted within the guide channel  28 . Guide channel  28  has been formed internally and generally along the horizontal X axis of the handle  31  region of the unique one piece lower receiver  12 . Guide channel  28 , as illustrated in this embodiment, passes completely through the handle  31  region of the one piece lower receiver  12  in a horizontally and continuous manner through and through lengthwise extending from the handle  31  rear region  30  and passing entirely through the trigger housing  34 , and whose interior dimensions are calibrated to, and conform with the corresponding phantom structural lines delineating the internal outline of the controller  14  within the handle. The guide channel  28  is fashioned with interior dimensions of length, breadth, depth, and height to allow, upon implementation, the exterior proportions and surface regions of the interfacing controller  14  to move unimpeded in a transverse lateral fashion within the same guide channel  28 . Guide channel  28  can be easily constructed, for example, during the machining of the unique one piece lower receiver  12  and/or by Original Equipment Manufacturers (OEM)&#39;s, which is easily understood by anyone familiar with the art. The removable controller  14  is shown mounted in place as illustrated with solid line contour, thereby delineating the forward region of the controller  14  and continuing representationally in partial phantom line as being located operationally within the one piece lower receiver  12  handle region and positioned accordingly through the interior of aforementioned guide channel  28 . The controller  14  can be easily constructed by anyone familiar with the art while following these teachings. 
     In further detail, still referring to the invention of  FIG. 1B  having controller  14  shown in a fixed and most forward stationary position and is intended, with operationally utility, to generally move along a horizontal X axis relative to the position and/or elevation of the firearm and in a constricted linear reciprocal motion within the formed guide channel  28  of the handle  31  region of the one piece lower receiver  12 . The controller  14  is structurally located through and through the trigger housing  34  and shown positioned through the controller guide  28  front region  28 A in direct alinement with the trigger rear region  38  of the trigger  36 . The controller  14  showing the structurally integrated and calibrated forward stop  26  which correlates in functional utility, as discussed in further detail below, with coinciding utilization of controller front  18 . In other words, during implementation of the novel utility and method, the controller front  18 , being limited in its forward motion by controller forward stop  26  makes tangental contact with the trigger rear region  38  of trigger  36  and thereby delineates the trigger reset point and, simultaneously, the forward longitudinal movement of controller  14 . 
     Referring now to the invention of  FIG. 1C  depicted within the sight region of FIG. 1  drawing sheet  1 / 18 , showing a simplified semitransparent perspective view of the controller  14  as a preferred embodiment of the present invention being independently shown and optionally removed from the guide channel  28  of the handle region of the one piece lower receiver  12  as previously illustrated within  FIG. 1B . The controller  14  expressing in this embodiment a frontal convex surface area illustrated as controller front  18  and a most rearward conformational region  16  contiguous to and in conformation with the upper and/or upper-innermost firing hand support area  24 . The controller  14  also shown having a preset and calibrated locatable rearward motion stop  20  illustrated in partial phantom for ease of understanding and hereinafter referred to as reward stop  20  or simply stop  20 . The rear conformational region  16  and frontal region  22  of the innermost hand support  24  of the controller  14  additionally support the internal surface region of the shooters innermost and/or upper-innermost region of the firing hand. The innermost hand support  24  as expressed in this embodiment, encompasses the calibrated forward motion stop  26 , hereinafter referred to as forward stop  26  or simply stop  26 . The external surface area of the innermost hand support  24  moreover serves as a conforming surface area with the innermost and/or upper-innermost region of the upper area of the firing hand generally between the inner region of the index trigger finger and inner web of the thumb region. The firing hand support  24  also serves to somewhat elevate the upper and/or upper-innermost region of the firing hand away from the surface of the handle. Of course, the aesthetic appearance of the illustrated controller  14 , including any accessories, may be subject to a wide variety of configurations and various interpretative expressions and representations while continuing to maintain the present inventions unique and novel utility and methodical application. The novel mechanism and utilitarian method may be manifest in a variety of other alternative embodiments, some of which are expressed below. The controller  14  related structural elements, for example, may be reconfigured adaptively in order to properly function and fit to the outside of the handle  31  while still conforming in utility to the instant invention. An alternate embodiment as described above would, for example, find beneficial employment with typical AR15 firearm type handles which are generally removable and replaceable and structured such that the instant invention would adaptively and easily integrate with the aforesaid modular handle type components. A modified and/or alternate version of this type of inventive expression can be seen illustrated and described below within  FIG. 9  through  FIG. 14 , within the sight surface of  FIG. 16  as  FIG. 16A ,  FIG. 16B , and  FIG. 16C  and depicted by  FIG. 17  and  FIG. 18  as further described and referenced below. 
     Referring now to the invention of  FIG. 2 , drawing sheet  2 / 18 , illustrating a left side semitransparent horizontal elevation showing the one piece lower receiver  12  in contour outline understood as representationally attached to the previously exemplified  FIG. 1A  M4 type carbine firearm (not shown in  FIG. 2 ) and having the mounted controller  14  positioned longitudinally and regionally shown in partial phantom as located within the interior guide channel  28 . The illustrative preferred embodiment of controller  14  is optionally removable as mentioned above in reference to  FIG. 1C  and may have structural variations in overall length, for example, in order to conform to the differing hand sizes of diverse firearm operators. The outline of the interior of guide channel  28  is shown delineated by heavy square dotted lines extending horizontally along the uppermost and lowermost interior boundaries of the guide channel  28  and additionally shown by heavy square dotted lines in curvature indicating both the most forward and most rearward regions of the interior of guide channel  28  in order to thereby illustrate the guide channel  28  front structural opening through the trigger housing  34  and rear structural opening through the handle rear  30 . Moreover  FIG. 2  is illustrated as showing trigger  36 , trigger housing  34  partially in solid contour line, and handle rear region  30 . The exterior solid region of handle rear region  30  is indicated by both a solid contour line  30  and a phantom stipple line  30 . The stipple line extending from the number  30  indicates the phantom handle rear region  30 , as seen transparently through the exterior portion of the controller  14 , where the controller  14  forward stop  26  makes full contact with the solid region of the handle rear region  30  thereby defining the longitudinal forward movement of controller  14 . Additionally shown in  FIG. 2  is the controller rearward stop  20 , the front region of the controller  18 , the rear region of the controller  16 , the front area of handle  32 , and the bidirectional stipple arrow  58  indicating the forward and rearward linear potential dynamic movement and/or momentum generally along the longitudinal horizontal X axis of the controller  14  within guide channel  28 . In further references below to arrow  58  the designated forward movement and/or momentum being exerted on the controller  14  will be indicated as  58   f  and the designated rearward movement and/or momentum being exerted on the controller  14  will be indicated as  58   r . The controller  14  may be fixed and lockable in its forward position with an elective detent type safety selector not shown but easily understood by anyone familiar with the art. Optionally, but not shown, the embodied removable controller  14  may also be expressed with a preferable locking mechanism having a detection system which may recognizes a unique identifier and/or other type of interfacing element being in possession of the designated firearm operator in order to lock and/or unlock the controller  14 . When controller  14  is forwardly locked the trigger cannot function or rotate rearward to the trigger discharge position. These types of discretionary locking and unlocking mechanisms, while not illustrated in this narrative, are easily understood by anyone familiar with the art and readily adaptive to the present invention. As illustrated in  FIG. 2  the contoured and encompassing heavy single chain-line delineates the surface area of the one piece lower receiver  12  which indicates a representative region of the depicted figurative firearm further illustrated in the following drawings of  FIG. 3  through  FIG. 8 . 
     In further detail, still referring to  FIG. 2  as an expression of the present invention, controller  14  is shown in its at rest and most forward position having the interior surface of the controller forward stop  26  in full contact with the solid exterior handle rear region  30  and the controller front  18  being illustrated as positioned most forwardly and fixed in place while not in full contact with the rear of the trigger  36 . Trigger  36  is shown in its stationary ‘at rest’ position which is the normal most forward and stationary position for trigger  36 . 
     Referring now to the present invention of  FIG. 3 , drawing sheet  3 / 18 , showing figurative one piece lower receiver  12  illustrated in contour outline representationally as a mounted and in place component of the entire firearm and shown reposed in an initial time sequence event to be followed by a consecutive series of related time sequence event illustrations, beginning inclusively with  FIG. 3  and continuing through  FIG. 8  thereby demonstrating one preferred embodiment of the novel method and mechanism of the present invention. 
     Still referring, in greater detail, to the present invention of  FIG. 3 . As a means to assist in the understanding of the teachings of the present invention, and in basic terms, the conventional and standard operating procedure utilized to discharge an initial round of ammunition from a typical firearm is briefly described below and thereafter in context as it relates to the novel innovation. In order to originate the rearward movement of the trigger  36 , as seen within the trigger housing  34 , to the trigger discharge location and thereby initiate the primary discharge event, the firearm operator uses the trigger finger of the firing hand, not illustrated but easily understood by anyone familiar with the art, to engage with and then pull the trigger  36  rotationally rearwards by application of lateralized pressure, in a standard shooting manner, by implementation of depicted rearward longitudinal trigger finger pressure  42  upon the trigger  36  thereby moving the trigger  36  to the locational point of ammunition discharge. That being understood, the instant invention differs from the normal and/or standard shooting method, as described above, in at least the following descriptive context. As shown in the present illustration of  FIG. 3 , the application of the rearward longitudinal trigger finger pressure  42  moves the trigger  36  independently backwards and/or rotationally rearward from its previous at rest and most forward position, being representationally shown here in broken phantom line, to contact point  44  where the trigger rear region  38  of the activated trigger  36  makes initial physical contact with the controller front  18 . 
     Referring now in still more detail to  FIG. 3  being the first view in a series of consecutive sequences as illustrated from  FIG. 3  through  FIG. 8 . The controller  14  forward stop  26  has been calibrated in such a way that when controller  14  is located in its most forward position the controller front  18  and the trigger rear region  38  make coinciding tangental surface contact at point  44  which has been calibrated by the forward stop  26  to be the exact and contiguous location for the trigger reset position of the trigger  36 . Contact point  44  will hereinafter be referred to as trigger reset position and/or trigger reset point  44 . The delineating aspect of the interfacing and adjustable modular controller stop  20  and its related utilization as a structural element of the controller  14  is referenced below. 
     In further detail, still referring to  FIG. 3 , while in preparation to shoot the firearm the operator supports the firearm by gripping the handle region of the one piece lower receiver  12  with his firing hand using normal equalized rearward supporting pressure  50  exerted on the front of the handle  32  and normal equalized forward supporting pressure  48  upon the handle rear region  30 . Utilizing a natural contraction of the firing hand the operator applies longitudinal forward pressure  40  upon the controller rear  16  surface region by bringing into service the upper and/or upper-innermost region of the firing hand while employing the controller inner hand support  24  by surface contact with the inner region of the firing hand while the firearm operator applies coinciding longitudinal rearward trigger finger pressure  42  upon the forward region of the trigger  36 . As seen in  FIG. 3  controller rear  16  being depicted with an alternate contoured conforming controller rear  16  surface region, and the overall length of the inner hand support  24  is somewhat altered compared to the controller rear  16  depictions as taught below in  FIG. 4  through  FIG. 8  and in the following alternate embodiments in order to demonstrate one of the many potential variations in design and expressions of the present inventive method and mechanism. 
     In further detail, still referring to  FIG. 3 , the referenced bidirectional phantom arrow  58  figuratively indicates the controller  14  as being suspended in a temporary balanced and stationary position, while portraying the potential kinetic bidirectional longitudinal motion of controller  14  generally along the horizontal X axis of the controller  14  within controller guide channel  28 . Of course the aesthetic appearance of controller  14 , including appurtenances, may be subject to a wide variety of expressions while continuing to maintain the operational method and innovative utility of the present invention. 
     Referring now to the present invention of  FIG. 4 , drawing sheet  4 / 18 , showing the figurative one piece lower receiver as illustrated in a right side contour outline view.  FIG. 4  is the second view depiction in a series of consecutive sequences as illustrated from  FIG. 3  through  FIG. 8 . The inventive expression is illustrated herein with an alternate contoured controller rear  16  as compared, for example, to the controller rear  16  depiction of  FIG. 3  and  FIG. 14  and shown spatially reposed in a moment of time leading up to the instant of the firearms primary discharge event. The operator of the firearm continues to apply a constant isometrically balanced forward longitudinal upper-innermost hand region forward pressure  40  and a constant isometrically balanced rearward longitudinal trigger finger pressure  42 . In order to initiate the primary discharge event the firearm operator employs the trigger finger of the firing hand, not illustrated here but easily understood, and applies rearward trigger finger pressure  42  upon trigger  36  thereby generating a rearward force  58   r  upon controller  14  generally along the controller  14  horizontal X axis and by that means moving the controller  14 , the controller stop  20 , and the trigger  36  in concert rearwards to trigger discharge point  46  using one of the following preferable methods. A first preferred method, primarily employed in order to accurately discharge a single round of ammunition, utilizes incremental rearward movement of the trigger  36  by decreasing innermost hand region forward pressure  40  upon controller  14  while applying a concurrently increasing rearward trigger finger pressure  42  upon the forward region of trigger  36  and thereby incrementally moving the controller  14  and conjoined structural components in a unified and simultaneous rearward motion  58   r  while maintaining a slightly imbalanced dynamic reciprocal isometric tension upon the controller  14 . Optional singular discharge method two occurs when the user increases the rearward longitudinal trigger finger pressure  42  against the trigger  36  such that the rearward longitudinal trigger finger pressure  42  is somewhat greater than the sustained reciprocal forward pressure  40  produced by the upper and/or upper-innermost region of the shooting hand generally along the controller  14  horizontal X axis. This operator adjusted increase in rearward longitudinal trigger finger pressure  42 , being greater than the counter balancing isometric tension exerted upon the controller  14  by forward pressure  40  applied to the controller rear  16 , will move the trigger  36  and the controller  14  incrementally rearwards while the controller  14  continues to be under the influence of slightly imbalanced persistent isometric tension produced by counter pressure applied to the controller rear  16  by the upper and/or upper-innermost region of the firing hand, thereby moving the controller  14  and trigger  36  in dynamic isometric tension and coinciding motion to discharge point  46 . The third preferable method involves the operator applying a sustained and equalizing pressure upon the controller  14 , as described above, while moving the trigger  36  and the upper and/or upper innermost region of the firing hand in conformation with controller rear  16  simultaneously rearwards in concurrent motion while maintaining sustained isometric tension upon the controller  14 . This preferred discharge method is primarily employed when the firearm operator chooses to discharge an initial round of ammunition to be quickly followed by a consecutive discharge event producing thereby a rapid sequential discharge and/or increased rate of fire. Either of the three alternate preferable methods employable in order to initiate the primary discharge event may be engaged while steadily holding the handle of the firearm with the operators firing hand. An alternate firing method, as applied to handguns in particular, is further described in the teachings below. Of course a rifle type firearm functioning in standard operational procedure typically requires the additional engagement of a forward supporting and/or stabilizing hand on the specified forward region of the rifle type firearm, such as the forward hand-guard region and/or the use of a vertical or similar type forward hand grip, neither of which is absolutely necessary for the utilization of the present invention. Advantageously, it should be readily understood that the initial utilization of the present innovation for the discharge of a primary round of ammunition does not require a secondary hand support, other than as an option and/or as required in normal firearm use, when the present novel invention is employed with either a handgun and/or a rifle type firearm. 
     In further detail still referring to the present embodiment of  FIG. 4 , during the rearward movement of the controller  14  the trigger rear region  38  continues to remain in constant tangental contact with the partially elliptic controller front  18  even as the trigger  36  terminates movement at discharge point  46 , being delineated by the controller rear stop  20 , conforming in coincidence with the location at which trigger  36  initiates the discharge of an initial and/or following single round of ammunition. It should be noted that the typical trigger of many firearm types, including the exemplary expression, normally rotates somewhat further backwardly from the actual ammunition discharge point. As illustrated, the novel expression of the present invention advantageously defines the exact discharge point of the trigger to coincide with the controller  14  rearward stop  20  such that when discharge point  46  is reached by trigger  36  the calibrated rearward stop  20  of the controller  14 , as depicted in this instant expression, makes full contact with the interior of the trigger housing  34  and in turn thereby simultaneously curtails the rearward movement and/or momentum of the controller  14  along its horizontal X axis. 
     Referring now to  FIG. 5 , drawing sheet  5 / 18 , of the present invention illustrating the third view in the series of three consecutive sequences as illustrated from  FIG. 3  through  FIG. 8  and depicting the firearm in moment of repose and in a subsequent time sequence event to that of  FIG. 4 . The depiction of  FIG. 5  shown positioned in a sequentially proportional spacial location and relative time constant wherein phantom exemplifications are represented by double dash chain lines. Controller forward stop  26  and controller rearward stop  20  are both shown in phantom stipple line. The trigger rear  38  reaches its most delineated rearward position at discharge point  46  while maintaining sustained and variable tangental contact with the elliptic controller front  18  and rearward controller stop  20 , as shown in phantom, contacts the trigger housing  34  and the firearm simultaneously discharges a single round of ammunition thereby generating recoil force  52 . 
     In further detail still referring to  FIG. 5 . Except for the isometrically isolated controller  14  the entire mass of the firearm including the lower receiver  12  moves rearwards under sustained influence of the recoil force  52  which coincidentally translates the firearm from its previous constant spatial location  54 , as illustrated in contour phantom chain-line, to a proportionately repositioned spatial location  56 , shown in solid contour line. During the discharge event, elements of the users shooting hand and/or supporting hand continue to provide some natural stabilization for the firearm thereby somewhat resistively countering recoil force  52 . The isometrically isolated controller  14  having reciprocal forward pressure  40 , produced by the innermost region of the shooting hand, persistently exerted in conformation upon controller rear region  16  with ongoing constant rearward longitudinal trigger finger pressure  42  exerted upon the trigger  36  which in turn thereby generates an ongoing constant and fluid tangental contact between the trigger rear  38  and the controller front  18 . 
     In further detail still referring to  FIG. 5 , as the initial discharge event progresses the controller  14 , while under the influence of continuing constant isometric tension along its horizontal X axis as described above, sustains a latent moment of inertia while remaining in a relative spatially fixed location in proportion to the mass of the firearm, the firearm being under continuing rearward kinetic influence from the initial recoil force  52 . As the consequent linear acceleration from the momentum of recoil force  52  persists and the entire mass of the firearm continues to move backwardly from its previous relative spatially location  54 , to its repositioned spatial location  56 , the controller  14  retains stored potential kinetic energy while remaining statically positioned relative to the mass of the rearward moving firearm. The controller  14 , while under the sustained influence of ongoing isometric tension, remains stationary in relative spatial proportion to the recoil force  52  and the ongoing recoil force effect generating the rearward momentum upon the mass of the firearm. In other words, the operator sustained isometric tension on controller  14  imparts persistent countervailing inertia on controller  14  in opposition to the dynamic recoil force  52  which in turn produces longitudinal force  58   f  generally along the controller  14  horizontal X axis and as a consequence thereby releases the stored potential energy of controller  14  effectively translating controller  14  in a uniform longitudinally reactive kinetic momentum to a repositioned spatial location relatively equivalent to its original pre-discharge position in relation to the mass of the firearm. The user sustained isometric tension on the controller  14 , in combination with the forwardly translating reciprocal interaction as described above, results in the trigger  36  moving congruently with the controlling mechanism forward to the trigger reset point  44  thereby reseting the trigger even as the controller forward stop  26  simultaneously reaches full contact with the solid region of the handle rear  30  thereby defining the forward movement and/or momentum of the controller  14  to the exact trigger reset point  44 . 
     Referring now to  FIG. 6 , drawing sheet  6 / 18 , of the present invention illustrating the firearm in moment of repose and in a subsequent moment of time in a continuing sequence following that of illustration  FIG. 5 . As the initial discharge recoil force effect has subsided the firearm has changed relative spatial location from the previous discharge position  54  shown in single chain line, to secondary position  56  shown in solid contour line, while continuing to be supported by the users firing hand applying equalized gripping forward pressure  48  and rearward pressure  50 . The controller  14  and trigger  36  shown having moved kinetically through the moment of inertia, as described above, to a more forward stationary position as the recoil event has subsided. Additionally the controller  14  forward stop  26  indicated in phantom by stipple line is shown in place forwardly against the solid rear region of the phantom handle rear region  30 , the controller rearward stop  20  being shown in its most forward position, the controller front  18  remaining in constant contact with trigger rear  38  of trigger  36  while under sustained trigger finger pressure  42 . Trigger  36  having reset itself at the calibrated trigger reset locational contact point  44 . The controller  14  remains under balanced isometric tension, shown in phantom as stippled double arrow  58 , under the continually sustained innermost hand region forward pressure  40  and the sustained rearward longitudinal trigger finger pressure  42  upon the trigger  36 . The firearm operator may now choose to discharge a secondary round of ammunition or not. If not then the user has the option to partially reduce, as needed, either the rearward longitudinal trigger finger pressure  42  and/or the innermost hand region forward pressure  40 . Alternately the user may simultaneously reduce forward pressure  40  and the rearward longitudinal trigger finger pressure  42  as needed or the user may simply remove the innermost hand region contact from the rear  16  of the controller  14  or the trigger finger contact from the trigger  36  and/or greatly reduce the the rearward longitudinal trigger pressure  42  from the trigger  36 . Removing and/or reducing trigger finger pressure and/or trigger finger contact with and/or influence on the trigger  36  as needed and/or releasing the supportive gripping force  48  from the handle rear  30  and/or releasing gripping force  50  from the handle front  32  and/or any combination of the above as needed will have the effect of ceasing any further sequential discharge of ammunition. It should be prescriptively noted that each and every discharge event is the result of an intentional choice that the operator of the firearm makes, whether volitionally, and/or intuitively, and/or instinctively. Minimally, each discharge event requires a combination of the firearm operators application of isometric tension upon the controller rear  16  together with the sustained presence of the trigger finger on the trigger  36  with continued isometric exertion of rearward lateral force trigger finger pressure  42  upon the trigger  36 . 
     Referring now to  FIG. 7 , drawing sheet  7 / 18 , of the present invention illustrating, in moment of repose, a subsequent consecutive time sequence event to that of illustration  FIG. 6 . The firearm operator, having decided to continue shooting the firearm, performs a secondary single discharge of ammunition by applying a somewhat similar procedure as described above in  FIG. 4 . Accordingly in this expression, the user continues to exert sustained isometric rearward longitudinal force  42  upon the trigger and a somewhat effectively balancing forward isometric longitudinal force  40  upon the controller rear  16  with the innermost firing hand utilizing support  24  while maintaining persistent contact between the rear of trigger  38  and the front of the controller  18  thereby exerting sustained isometric tension on the isolated controller  14 . The above and previously described uninterrupted isometric tension exerted on controller  14  generally vectors along the controller  14  horizontal X axis while producing a sustained moment of inertia, with stored kinetic energy, upon the controller  14 . However, alternately and in differentiation with the instant inventions firing procedure for the initial discharge event, as described above in  FIG. 4 , the firearm operator is expressively, in this instance, choosing to discharge a secondary round of ammunition while the mass of the firearm is continuing rearward under the sustained influence of recoil force and may therefore discharge the secondary and/or following round of ammunition by intentionally and volitionally maintaining natural hand contraction and ongoing isometric tension upon the controller  14  which, in combination with a minimal recoil counter balancing effect of the supporting hand(s) when utilizing a rifle type firearm and in consequence of the combined effect of the above influences, thereby spatially repositions the controller  14  proportionally rearwards while the controller  14  remains effectively under the influence of the relatively static, corresponding, and isometrically sustained reciprocal kinetic force  58   r . The resulting repositioning of the controller  14  simultaneously brings the controller forward stop  20  into direct contact with the trigger housing  34  and the trigger  36  rotationally backwards to the defined trigger discharge point  46  and as a consequence thereby initiating a secondary and/or a following ammunition discharge event. 
     Referring now to  FIG. 8 , drawing sheet  8 / 18 , of the present invention illustrating the firearm in moment of repose and subsequent time sequence event to that of illustration  FIG. 7 .  FIG. 8  shown having progressed rearward in a relatively fixed spatial location subsequent to the foregoing effects of the secondary ammunition discharge event as described in  FIG. 7  and now shown in  FIG. 8 , wherein phantom exemplifications are represented by double chain lines, excepting controller forward stop  26  and controller rearward stop  20  depicted in phantom stipple line. During the secondary discharge event as previously described in the above  FIG. 7  and presently illustrated in contoured phantom double dash chain line, the trigger rear  38  reached its most delineated rearward position at trigger discharge point  46  while in sustained variable tangental contact with the controller front  18 . The rearward controller stop  20 , shown in phantom, contacted the trigger housing  34  and the firearm discharged a single secondary round of ammunition thereby generating the resulting recoil force  52 . The phantom double dash chain lines outlining the trigger  36 , the controller  14 , and constituent elements indicate that, as the secondary discharge event took place, the recoil force  52  again sent the body of the firearm rearwards from secondary spatial position  56 , shown in darker phantom single dash chain line, to a tertiary spatial position  60  as illustrated in solid contour line, while the forwardly sustained isometric tension  40  exerted on the controller  14  controller rear  16  by the upper innermost region of the firing hand enabled the dynamically stored kinetic force  58   f  to release and/or move the controller  14  through the moment of inertia in equal and opposite reciprocal action to the recoil force  52 . This progressive event is further described in greater detail below. 
     In further detail still referring to  FIG. 8 , except for the isometrically isolated controller  14  the entire mass of the firearm including the lower receiver  12  moved rearward under the sustained influence of the secondary recoil force  52 . Elements of the users shooting hand and/or supporting hand continued to provide some natural stabilization for the firearm and thereby somewhat resistively countering the secondary recoil force  52  providing an additional element of control to the firing sequence and accuracy to the shot. The isometrically isolated controller  14  continued to have sustained reciprocal forward pressure  40 , produced by the innermost region of the shooting hand, exerted upon rear of the controller  16  and persistent rearward longitudinal trigger finger pressure  42  exerted upon the trigger  36  which in turn created an ongoing and continual contact between the trigger rear  38  and the controller front  18 . 
     In further detail still referring to  FIG. 8 , as the secondary or following discharge event progressed the controller  14 , while influenced by the persistent volitionally applied isometric tension generally along horizontal X axis, sustained a latent moment of inertia, while the controller  14  remained in a relative fixed spatial location proportional to the secondary recoil force  52  and the recoiling mass of the firearm. As the consequent linear acceleration from the momentum of secondary recoil force  52  persisted, the entire mass of the firearm including lower receiver  12  continued to move rearwards from its previous relative spatially location  56  to a new and repositioned spatial location  60 . The controller  14 , retaining stored potential reciprocal energy, temporally remained in static position under the steady influence of ongoing and sustained isometric tension and persisted in its relative fixed spacial location in direct proportion to the impetus of secondary recoil force  52  and the concomitant ongoing kinetic rearward momentum of the mass of the firearm. Sustained isometric tension exerted on controller  14 , as referenced above, imparts countervailing inertia on controller  14  in opposition to the dynamic secondary recoil force  52  effectively producing corresponding lateral force  58   f  generally along the controller  14  horizontal X axis. The isometrically stored potential energy of controller  14  when incorporated by lateral force  58   f  uniformly translates controller  14  longitudinally forward with concomitant reactive kinetic momentum thereby generating a resultant forward repositioning and relative forward spatial location upon the controller  14  comparatively equivalent to the original position of controller  14  in relation to the mass of the firearm and the lower receiver  12 . The user sustained isometric tension on the controller  14 , in concert with the forwardly translating reciprocal interaction as described above, results in the trigger  36  moving congruently forward to the trigger reset point  44  as the controller forward stop  26  simultaneously reaches full contact with the solid region of the handle rear  30  thereby defining the forward movement and/or momentum of the controller  14 . In other words, the firearms discharge event produces a rearward recoil force effect on the mass of the firearm while the volitionally sustained isometric tension exerted upon the isolated controller mechanism imparts persistent countervailing inertial resistance to the recoil event thereby neutralizing the recoil effect upon the controller mechanism. As the mass of the firearm continues rearward from the recoil force, the isolated controller mechanism reciprocally translates the controller, trigger, and trigger finger forwardly through the moment of inertia thereby reseting the trigger mechanism. As the discharge event subsides the expressed elements of  FIG. 8  would be illustratively similar to the expressed elements of  FIG. 6  in every way except that the mass of the firearm has been somewhat spatially repositioned, as discussed, from the recoil force of the secondary and/or following discharge event and the resultant recoil effect. Following the above expressed and referenced series of events the firearm operator may now choose to discharge a following and/or consecutive round of ammunition by application of the novel method as earlier described in reference to  FIG. 6  or the operator may optionally choose not to discharge a following round of ammunition by adhering to the same method and utility as previously described in reference to  FIG. 6 . The utilitarian interaction of the referenced consecutive series of illustrations as shown in  FIG. 3  through  FIG. 8  of the present invention can of course be understood to occur in a very rapid consecutive sequence and time constant. The choice to discharge a following round of ammunition and/or a consecutive discharge sequence after the initial discharge event becomes a volitional act of the firearm operator and, after some practice, almost an intuitive and on the fly choice. 
     Referring now to  FIG. 9 , drawing sheet  9 / 18 , wherein an alternate expression of the novel invention is illustrated having the same utility as that which has been conveyed above. The depicted and outlined two piece lower receiver  12 , in differentiation to the previously diagramed one piece lower receiver  12  as shown in FIG. 1  through  FIG. 8 , now illustrated as having a removable handle  31  as a standard feature of factory manufactured AR15 and/or M4 carbine or rifle type firearms. In this alternate expression the innovative controlling mechanism is structurally attached to the right side of the handle  31  region of the two piece lower receiver  12  in some differentiation to the previously described center controller and/or center controlling mechanism. A controller housing  61  is shown containing controller  14  which moves laterally and transversely within the controller housing  61 . The alternate utility and structural position of controller  14  within controller housing  61  being diagramed and discussed in further detail below. Controller  14  having a forwardly locatable and adjustable modular element shown as rearward controller stop  20  and having a rearward locatable and adjustable forward controller stop  26 . Rearward controller stop  20  and its structural elements governing the most rearward motion of the controller  14  with forward controller stop  26  and its structural elements governing the most forward motion of controller  14 . The rearward controller stop  20  having surface region  20 C serving as a structural surface area which interacts tangentially with the trigger rear region  38  of the trigger  36  in the same manner as the previously described center controller front  18  interacts with the trigger rear region  38  of the trigger  36  as earlier discussed and shown in  FIG. 3  through  FIG. 8 . The presently illustrated controller  14  forward controller stop  26  having a conforming rear region  16 , as depicted in partial phantom, which interacts with the innermost and/or upper innermost region of the firing hand in the same utility and method as the conforming rear region  16  of controller  14  as discussed in  FIG. 3  through  FIG. 8 . The structural elements of forward controller stop  26  and structural elements of rearward controller stop  20  operatively interact with regions  62 F and  62 R of the controller housing  61  in the same utility, method, and manner as the earlier described rearward controller stop  20  and forward controller stop  26  reciprocally interact with the handle rear region  30  and the trigger housing  34  of the lower receiver  12  as depicted in  FIG. 3  through  FIG. 8 . 
     Referring now to the present invention of  FIG. 10 , drawing sheet  10 / 18 , depicting an alternate controlling mechanism positioned and located on the right side of the two piece lower receiver  12 . The forward region of controller  14  is partially shown, opaquely and most forwardly in place, within controller housing  61 . Controller  14  having controller rearward stop  20 , in this expression, shown positioned laterally behind the rear surface region  38  of the trigger  36  interfacing thereby with the rear surface region  38  of the trigger  36  in similar function and utility as the earlier depicted controller front  18  in  FIG. 3  through  FIG. 8 . Controller  14  having locatable and adjustable modular forward stop  26 , shown in partial phantom view for ease of understanding, being in its most forward position behind the handle rear region  30 . The controller guide channel  28  being depicted in phantom within the separately diagramed fully transparent controller housing  61  shown illustrated in place rearwards of the located version of the controller housing  61 . Illustrated within transparent controller housing  61  controller guide channel  28  shown structurally accommodating the exterior linear surface region of controller  14  with conforming internal dimensions of height, width, and length portrayed in phantom within transparent controller housing  61 , controller guide channel  28  structurally allowing the controller  14  to move in unimpeded, transverse, and lateral motion within the controller guide channel  28 . 
     In further detail referring now to  FIG. 10 , depicting controller housing  61  further represented in semi-transparency and illustrated laterally and to the right side of the located position of controller housing  61  on handle  31 . The right side semi-transparent controller housing  61  referred to hereinafter as the right side semi-transparent controller housing  61 . The right side semi-transparent controller housing  61  having two locating structures indicated by a single line and reference number  63 A, for ease of understanding and illustration, and two controller housing fasteners indicated by reference  63 , which fasten the controller housing  61  to the handle  31 . Locating structures  63 A pass through and through the solid region of the right side semi-transparent controller housing  61  without interfering with the movement of controller  14  within the guide channel  28  of the right side semi-transparent controller housing  61 . The controller housing fasteners  63  are shown removedly from the handle  31  region and the right side semi-transparent controller housing  61 . The structural outline of controller  14  being shown in phantom within the controller guide channel  28  of the semi-transparent controller housing  61 . Controller  14  shown having forward location  64  being structured for receiving the rearward stop  20  and rearward location  65  being structured for receiving the forward stop  26 . The right side semi-transparent controller housing  61  illustrates the outline of controller  14  in phantom being positioned rearwards within the controller guide channel  28 . The rearward stop  20  shown removedly from the forward mounting location  64  of controller  14  and the forward stop  26  shown removedly from the rearward mounting location  65  of the controller  14 . 
     In greater detail still referring to the present invention of  FIG. 10  depicting the fully transparent controller housing  61 , shown to the rear of the normally located position of controller housing  61  on handle  31 , and illustrating concave forward region  62 F which interacts in utility with the surface structure region of controller rear stop  20  in order to interactively delineate the firearm trigger  36  normal discharge position. Fully transparent controller housing  61  additionally shows concave rear region  62 R which interacts operatively with the surface structure region of controller forward stop  26  to accurately delineate the firearm trigger  36  normal reset position, not shown but easily understood from earlier teachings. Controller forward stop  26  and controller rear stop  20 , being adjustable modular elements, interact with concave rear region  62 R and concave forward region  62 F of controller housing  61  in the same utilitarian manner and fashion as the controller stops referenced above in  FIG. 3  through  FIG. 8 . In other words and as previously taught, the forward controller stop  26  and the rearward controller stop  20  operatively interact with regions  62 F and  62 R in the same utility, method, and manner as the earlier described rearward controller stop  20  and forward controller stop  26  interact with handle rear region  30  and trigger housing  34  as previously illustrated in  FIG. 3  through  FIG. 8 . This similar methodical interactive utility is specifically described and illustrated in greater detail in the following teachings. 
     Still referring in greater detail to the present invention of  FIG. 10 , controller rear stop  20  having external structural region  20 B being raised above the surface of controller housing  61  such that external structural region  20 B, in operational utility and in rearward transverse longitudinal motion concurrent with the controller  14 , makes tangental contact with the surface region of the concave forward region  62 F of controller housing  61  thereby delineating the rearwards motion of controller  14 . Moreover, the concave forward region  62 F of the surface of controller housing  61  effectively interacts with the raised structural region  20 B of the controller rear stop  20  in similar manner as the trigger housing  34  earlier discussed and described in  FIG. 3  through  FIG. 8 , acts as a rearward surface region which effectively stops the transverse rearward motion of the controller rear stop  20 . Additionally, the forward stop  26  raised structural region  26 B interacts operatively with the concave rear region  62 R of the controller housing  61  in order to delineate and effectively impede the controller  14  in its forward transverse and lateral motion within the controller guide channel  28 . This configuration thereby establishing the trigger reset position as the most forward tangental contact point between the surface region  20 C of controller rear stop  20  and the surface area of the trigger rear region  38  of trigger  36  referenced earlier as trigger reset position  44  in  FIG. 3  through  FIG. 8 . The modified and/or alternate structure and method of the novel expression is further discussed and diagramed below in  FIG. 11  through  FIG. 13 . 
     Referring now to the present invention of  FIG. 11 , drawing sheet  11 / 18 , therein illustrating a simplified semitransparent partial schematic right side elevation of the novel alternate expression of  FIG. 10  and depicting the figurative lower receiver  12  shown in contour outline having trigger  36  in its most forward and at rest position.  FIG. 11  showing the invention reposed in an initial time sequenced event thereby demonstrating the first sequence in a series of three depicted events, inclusive of  FIG. 11  through  FIG. 13 . Controller  14  is referenced by both solid line, indicating the forwardly exposed region of the controller  14  outside of the controller housing  61 , and by phantom stipple line indicating the controller  14  interior region as seen in place within the semi-transparent controller housing  61  and having adjustably locatable forward stop  26  and adjustably locatable rearward stop  20  positioned in place. Forward stop  20  shown having surface region  20 C effectively acting as the front of and/or most forward contact region of controller  14  and which interacts in tangent with the trigger rear region  38 . Controller rear stop  26  shown having rear surface region  16  providing a generally conforming surface area intended in order to interface with the upper-innermost region of the firearm operators firing hand, not shown but easily understood from earlier teachings. Controller  14  illustrated in its most forward position with forward stop  26  making full contact with region  62 R of controller housing  61 . Forward stop  26  shown in a most forward position and, in this alternate expression, not required to be in physical contact with the handle rear region  30 . The forward stop  26  utilizes region  62 R of the controller housing  61  as the most forward contact surface, as discussed above, rather than the handle rear  30  as earlier described in  FIG. 3  through FIG. 8 . The handle rear region  30  is illustrated in both solid contour line and by heavy broken line being visible, for ease of understanding, through the partially transparent controller housing  61 . Controller housing  61  is shown having concave forward region  62 F which operationally interfaces with the structural surface region of rearward controller stop  20  as discussed above and further referenced below. 
     Referring now to  FIG. 12  , drawing sheet  12 / 18 , illustrating the lower receiver  12  having an alternate preferred embodiment of the instant novel mechanism attached therewith, and wherein the method of operational utility for a modified form of the novel invention is described.  FIG. 12  showing the novel invention momentarily reposed in a time sequence event demonstrating the second sequence of a three sequence discharge event depicted by  FIG. 11  through  FIG. 13 . In similar functionality and utility to the referenced operational method of the novel invention, as described above in  FIG. 3  through  FIG. 8 , the firearm operator initiates the discharge event by holding the handle  31  in a standard manner with the innermost region of the interior of the firing hand, not shown but easily understood, upon handle rear  30  and coincidentally applying forward force  40  upon the conforming surface region  16  of forward stop  26  with the upper-innermost region of the firing hand. The firearm operator then applies trigger finger pressure and/or force  42  to the front region of the trigger  36  by utilizing the trigger finger of the firing hand, not shown but easily understood, thereby bringing the trigger rear region  38  into tangental contact with the controller  14  rearward stop  20  surface region  20 C. Methodically, the firearm operator continues to maintain constant and equalizing forward force  40  exerted by the upper-innermost region of the firing hand upon conforming surface region  16  of forward stop  26  thereby creating an intentionally static isometric tension upon the controller  14 . The surface contact point of the trigger rear region  38  and the controller  14  rearward stop  20  surface region  20 C being preset and/or calibrated to interactively establish the trigger reset position  44 . 
     Referring in more detail to  FIG. 12 , if the user is intending to discharge a single round of ammunition, such as when operating a bolt action and/or semi-automatic firearm in an extremely accurate manner, the shooter may utilize the alternate novel present invention and methodology to move the trigger  36  incrementally rearwards to the locational point of trigger discharge. Employing the utility of the novel method the firearm operator maintains rearward force  42  upon the trigger  36 , thereby maintaining tangental surface contact between the trigger rear region  38  and the controller stop  20  surface region  20 C, while slowly decreasing forward force  40  upon conforming surface region  16  of forward stop  26  by the gradual relaxation of the isometric tension of the upper-innermost region of the firing hand upon conforming surface region  16  of the forward stop  26  of controller  14  until the trigger discharge point  46  is reached as seen and referenced below in  FIG. 13 . This novel and unique shooting method adds considerably improved trigger feel and accuracy to the discharge event while increasing the overall operator control of a singular discharge event by augmenting and enhancing the traditional relationship between the interior region of the firing hand, the trigger finger of the firearm operator, and the trigger  36 . 
     Referring now in greater detail to  FIG. 12 , as the isometric tension upon controller  14  begins to be incrementally adjusted as described above, the controller  14  and related components will begin to move rearward thereby separating the surface region of forward stop  26  from controller housing concave surface region  62 R while the rearward stop  20  of controller  14  will begin to move rearward toward controller housing concave surface region  62 F. This unique and novel interaction is further illustrated and described below in  FIG. 13 . 
     Referring now to  FIG. 13 , drawing sheet  13 / 18 , wherein lower receiver  12  shown having an alternate preferred embodiment of the instant mechanism attached therewith, and wherein the method of operational utility for the present and novel invention is depicted in momentary repose as the third illustrative step and final progression in a series of three consecutive portrayals inclusive of  FIG. 11  through FIG. 13 .  FIG. 13  showing controller  14  in its most rearward position having had isometric tension upon controller  14  incrementally adjusted rearwards, as described above, with ongoing rearward trigger finger pressure  42  being exerted upon trigger  36  while having rear trigger region  38  in continuous tangental contact with the controller front  20 C surface region of rearward stop  20  while the innermost region of the firing hand exerts lessened forward force  40  upon conforming surface region  16  thereby allowing forward stop  26  to move incrementally rearward from its former contact with controller housing concave surface region  62 R. The rearward stop  20  being calibrated to contact the controller housing concave surface  62 F at the simultaneous moment in time that the trigger  36 , having moved incrementally rearward reaches trigger discharge point  44  thereby generating a well governed, extremely accurate, and beneficially controlled singular ammunition discharge event. The firearm operator may utilize the above described method to discharge a single round of ammunition and/or the user may choose to fire a secondary and/or follow up sequential round of ammunition by simply maintaining a constant isometric tension upon controller  14  while following the earlier procedure described above in  FIG. 3  through  FIG. 8 , rather than a variable isometric tension and incremental movement of the trigger as applied by the firearm operator for a singular discharge event as just discussed. The removable and interchangeable controller  14 , as referenced in the above teachings, having locatable and adjustable modular elements and an availability of overall lengths thereby enables the firearm operator with the ability to interchange controller  14  in order to conform the controller mechanism in order to fit smaller and/or larger hand sizes and, with additional modifications, adjust the interaction between the controller  14  and the individual firearm&#39;s trigger reset and trigger discharge points as referenced above. 
     Referring now to the present invention of  FIG. 14 , drawing sheet  14 / 18 , showing a left side elevation of the novel invention having controller housing  61 , seen located on the opposite side view of two piece lower receiver  12  and in partial transparency as delineated by solid contour and heavy broken line, and having therein controller  14  shown in partial transparency as delineated by solid contour line and phantom stipple line.  FIG. 14  depicting an alternate and/or modified utilization method, illustrating a singular discharge event, and having a simplified example of a novelly expressed firing hand thumb rest  66 , illustratively located on the left side of handle  31  for use by a right handed shooter for example, in contour outline and being a locatable element on the left hand side of the handle  31 . The thumb rest  66 , as illustratively attached to the handle region  31  of the two piece lower receiver  12 , is generally locatable in its positional utility. The thumb rest  66  herein expressed in order to further exemplify an alternate and/or modified method of utilizing the current innovation while employing controller  14  expressively within the side mounted controller housing  61  and, in further continuance below as depicted in perspective view  FIG. 15 , utilizing center controller  14  within a one piece lower receiver  12 . As a means to incorporate the thumb rest  66  with operational utility of the novel invention, the firearm user exerts normal contraction of the shooting hand as described above while pressing the front area of the firing hand thumb region, not shown but easily understood, forwardly against the concave inner area  64  of the thumb rest  66  while exerting thumb region forward pressure  68  upon the concave inner area  64  of the thumb rest  66 . 
     In further detail still referring to the present invention of  FIG. 14 , in this preferred embodiment, similar in its utilitarian employment as previously described, having the user synchronistically apply upper innermost hand forward pressure  40  to surface region  16  of forward stop  26  and rearward trigger finger pressure  42  to trigger  36  thereby generating tangental interface between trigger rear  38  and rear stop  20  at trigger reset point  44 . This interaction, along with the application of simultaneous thumb region forward pressure  68  against thumb rest  66  concave inner area  64  and normal equalized gripping pressure  50  exerted on the front of the handle  32  with pressure  48  upon the rear of the handle  30 , effectively creates sustained isometric tension upon controller  14  and thereby isolates the potential movement of the controller  14  by statically positioning the relative spacial location of controller  14  relative to the two piece lower receiver  12  and the main body of the firearm. The above interaction also establishes isometrically sustained equilibrium generally along the linear horizontal X axis of the controller  14  along with a somewhat coinciding forwardly sustained tension upon the frame of the firearm thereby generating an isometrically stabilized tension between the firing hand of the user, the controller mechanism, and the overall frame of the firearm in anticipation of the initial, secondary, or a following sequential discharge event and the resultant natural recoil effect on the firearm. The above described interaction achieves a reciprocally suspended and kinetically sustained static-isometric tensioning and effect between the firing hand, the controller mechanism, and the overall frame of the firearm such that the isometrically stored static tension, as discussed above, is generally released concomitant with the discharge event and thereby intrinsically employed to naturally stabilize and somewhat offset the ongoing rearward impetus of the firearm, generated from the recoil effect, with a counterbalancing and stabilizing force which has a somewhat neutralizing influence upon the firearms recoil momentum stemming from the initial and any closely following discharge of ammunition. Once the firearm user has employed the innovative method, thereby establishing the isometrically balanced interactive relationship between the firearm and the inventive elements, and in order for the user to initiate a primary discharge event, the user applies coinciding and incrementally increasing rearward trigger pressure  42  on trigger  36  simultaneously with incrementally increasing forward pressure  68  on the trigger finger rest  66  concave inner area  64  while the upper-innermost hand region naturally sustains forward pressure  40  on the controller forward stop  26  region until the trigger  36  reaches the discharge point, not shown but easily understood. This referenced firing sequence, as generated by the herein discussed alternate shooting technique, adds a unique and novel governing method for the management of incremental trigger movement while adding enhanced control over and increased accuracy to a singular discharge event. In addition the novel governing method enables the firearm operator with the ability to volitionally choose to either cease the firing sequence by relaxation of the employed elements of the firing hand and/or to rapidly discharge a secondary and/or following sequence of discharge events when using a semi-automatic firearm. When using a semi-automatic firearm, a secondary and/or following discharge event results when the firearm user simply maintains the established isometric tension upon the controlling mechanism by utilizing the earlier described method and teachings, or the firing sequence may be interrupted and/or limited to a single discharge event when the user simply relaxes the overall tension of the firing hand and/or thumb region and/or the upper innermost region of the firing hand. 
     Still referring to the present invention of  FIG. 14 , the described integration of the stabilizing thumb region forward pressure  68  against the thumb rest  66  concave inner area  64  while utilizing the alternate method may be more frequently and/or optionally employed by the novel inventive method when utilized in the one handed operation of a handgun, and perhaps less frequently required and/or not always needed and/or necessary for the two handed operation of the present invention when using a hand gun and/or a rifle type firearm, the differentiation being further expressed below. For ease of understanding, illustration, and narrative purpose the diagramed thumb rest  66  and integral elements as appearing in  FIG. 14  are comparatively shown again in perspective view as illustrated in  FIG. 15 . However, the thumb rest  66  and interactive shooting method are not uniformly illustrated within the novel exemplifications and depictions even though the functional equivalent may be implied, understood in potential application, and arbitrarily employed in utility by the firearm operator. As discussed, the application of thumb region forward pressure  68  and conformational implementation of the inner thumb region upon the thumb rest rear region  67  of thumb rest  66  is expressed as a discretionary aspect of the present invention method, being illustrated and described herein as an alternate method for the utilization of the present novelty. Furthermore, the alternate method and modified utility is not intended as a mandatory and/or conditional requirement in every shooting scenario but is expressed in this narrative as an alternate, optional, and/or coinciding method for the employment of the immediate invention, and optionally, inclusive with the one handed operation of handguns and rifle type firearms in particular, and to assist with the previously described method in order to increase the accuracy and control of individual singular discharge events such as is required in more precise shooting scenarios. Any references herein to the inventive employment of the innermost and/or the upper innermost region of the firing hand should be understood to optionally include the arbitrary use of the thumb region and/or thumb region forward pressure  68  and/or the thumb rest  66  without characterization thereto. This alternate method, when optionally incorporated by the firearm operator, effectively works in tandem with the expressed interactive utilization of controller  14 , as a function of the present invention, to help initiate the firearms primary discharge and/or any following discharge events as employed in utility by the present invention for one-handed operation of handguns for example, as previously discussed, and may be incorporated to assist in initiating a primary, secondary, and/or sequential discharge event when operating semi-automatic firearms in general. Additionally, the expressed thumb rest  66  is structurally locatable and adjustable, not shown but easily understood by anyone familiar with the art, in order to conform advantageously with the users firing hand when employing the instant invention innovative mechanism and method. 
     Referring now to the invention of  FIG. 15 , drawing sheet  15 / 18 , illustrating an extremely simplified perspective side view of a representational one piece lower receiver  12  depicted as having an opaque solid surface and shown reposed in an initial time sequence event being illustrated in comparative parity to the previously expressed center controller depiction of  FIG. 1  through  FIG. 8 , and employing an alternate method to the depicted center controller  14  novel expression. The present invention of  FIG. 15  showing thumb rest  66  expressed in perspective view to enable a greater ease of understanding of the innovative method.  FIG. 15  in this depiction currently showing a differing contour of the controller  14  rear region  16  as compared to that of  FIG. 3  and  FIG. 14 , but continuing to be similar in its utilitarian function as the earlier referenced controller  14  rear region  16 .  FIG. 15  illustrating the general application of the upper and/or upper-innermost shooting hand pressure  40  upon controller  14  rear region  16 . Additionally  FIG. 15  illustrates the firearm having normal firing hand pressure  50  exerted on the front of the handle  32  and normal firing hand pressure  48  upon the rear of the handle  30 . Trigger  36  is shown in its most forward at rest position and not yet in full contact with the controller  14  front region  20 C, having trigger finger pressure  42  not yet fully applied to the firearm trigger  36 . 
     In further detail still referring to  FIG. 15  showing the left side view surface area of the handle region of the lower receiver  12 , having an illustrative locatable thumb rest  66  having concave inner area  67  as seen in contour line and internal phantom line. In this expressed exemplification the firing hand forward thumb region, not shown but easily understood, is placed against the rear region  67  of the thumb rest  66  and, in operational utility as discussed above, the firearm user applies forward thumb region pressure  68 , thereby creating static tension between the firing hand forward thumb region and the thumb rest  66 , resulting in a natural isometric tension which, as described previously, generates a sustained and statically stabilizing influential effect between the firearm, the firing hand, the novel controlling mechanism and the firing hand forward thumb region. The operator initiates the primary discharge event by following earlier protocols as previously discussed and illustrated. 
     Referring now to  FIG. 16 , drawing sheet  16 / 18 , wherein an alternate expression of the present novel invention is illustrated. Within the sight region of  FIG. 16  depiction  FIG. 16A  illustratively and figuratively diagraming an M4 and/or AR15 type firearm, having a two piece lower receiver  12  with a removable handle  31  encompassed therein by a delineating single chain line. Handle  31  shown separately by enlarged view within the sight region of  FIG. 16  seen depicted in  FIG. 16B  and  FIG. 16C  shown connected by a single chain line to the depicted handle  31  region of  FIG. 16A .  FIG. 16B  and  FIG. 16C  representing the same structures and mechanisms for ease of understanding however, in differentiation,  FIG. 16C  shown having a fully transparent controller  14  and handle  31  region in order to illustrate the internal components of the alternate mechanism being shown in greater detail and further described below in  FIG. 17 , therein depicting an exploded view of  FIG. 16C  for ease of understanding.  FIG. 16C  shown having cross-hatching of the handle surface region removed for clear placement of the indicating reference numbers.  FIG. 16B  and  FIG. 16C  show controller  14  having interior longitudinal phantom line  14 C indicating the lower region of the conforming inner surface region of controller  14  along the controller  14  horizontal X axis, being depicted in longitudinal tangental contact with the corresponding handle  31  right side exterior surface region. Additionally illustrated in  FIG. 16B  and  FIG. 16C  are controller rearward stop  20 , controller rearward stop front region  20 C, controller front  18 , and handle rear region  30  having mounting locations  69  integrated within the controller  14  innermost surface region and structured to accept the locatable controller guide pins  67  which move transversely and freely within guide pin locations  68 . The single reference lines should be understood to indicate both structural locations  69 , both controller guide pins  67 , and both guide pin structural locations  68 . The utilization and detailed functional interaction of the novel invention, including a detailed description of the internal components as seen in  FIG. 16C , are further referenced below by exploded and enlarged view as illustrated in  FIG. 17 . 
     Referring now to  FIG. 17 , drawing sheet  17 / 18 , wherein an alternate expression of the present novel invention is illustrated as if removed from the firearm and in an enlarged and exploded view of the earlier depiction of  FIG. 16C .  FIG. 17  showing a transparent controller  14  having a solidly illustrated surface region of the controller front  18  where rearward stop  20  structural position and location  66  is depicted.  FIG. 17  showing locatable modular rearward stop  20  being separated from its fixed position within structural mounting location  66  on controller front  18 . A single chain line connects the controller stop  20  with the controller front  18  structural location  66  indicating the normal mounted position of controller stop  20  within structural location  66 . The controller  14  depicted with structural locations  69  integrated within the controller  14  innermost region, generally placed in the lower area of the controller forward stop  26 . Structural locations  69  are arranged to accept the controller guide pins  67  which are also shown connected by broken single chain lines to the two controller guide pin locations  68  indicating the two controller guide pins  67  positions within the mounting locations  69 . In operational utility the controller  14  is oriented upon the handle  31  with the controller guide pins  67  being located within the controller structural locations  69 . When fixed in place on controller  14  the controller guide pins  67  are thereby arranged in order to slide into the two controller guide pin mounting locations  68  and by that means enabling the the two controller guide pins  67  to move without hindrance transversely within the two controller guide pin structural locations  68 . The controller guide pins  67  have the dual function of acting as guides for the transverse movement of the controller  14  and are adjustably locatable and precisely calibrated to regulate the most forward movement of the controller  14  and thereby the most forward fixed position of controller stop  20 . In other words the two controller guide pins  67  adjust in effective length within mounting locations  69  beneficially thereby adjusting the overall exposed forward surface length of the two controller guide pins  67 . This structural adjustment influences the most forward contact point that the two controller guide pins  67  make with the interior surface region of the controller guide pin mounting locations  68  and by consequence thereby adjust the overall distance the controller  14  travels forward. The ability to modify the overall distance the controller  14  moves forwardly changes the most forward distance that the controller rearward stop  20  travels and thereby adjustably modifies the trigger reset point when employed in this expression. Since various firearms have differing trigger reset points, the novel inventions ability to have an adjustable controller mechanism enables a much wider and adaptive application of the instant novel alternate expression. This structural interaction is further described and illustrated below. 
     In more detail, still referring to  FIG. 17 , the controller stop  20 , when properly fixed in place as previously illustrated in  FIG. 16B  and  FIG. 16C , will enable controller stop  20  surface region  20 C to make tangental contact with the the rear region of the trigger, not shown here but easily understood, in the same tangental and useful way as the formerly illustrated controller front  18  effectively thereby serving the same utility, function, and novel methodology as the earlier expressed alternate structure of controller front  18 . In other words and without needlessly re-illustrating  FIG. 3  through  FIG. 8 , the controller stop  20 , as depicted in  FIG. 17  and when mounted on the controller  14 , is positioned such that when the firearm trigger is pulled rearward from its most forward and at rest position as earlier described, the rear trigger region of the trigger, not shown but easily understood, makes surface contact with the most forward elliptical surface region  20 C of controller stop  20 . This operational utility is comparable in every way to that of the previously illustrated and described interaction depicted in  FIG. 3 , for example, wherein the trigger rear  38  makes initial tangental contact with controller front  18  at trigger reset point  44 . In this instant expression of  FIG. 17  the controller stop  20  forward surface region  20 C serves the same function as the controller front  18  of  FIG. 3 , for example, and has been forwardly positioned by the interactive mechanism of the two controller guide pins  67  which adjust the forward movement of the controller  14  and thereby the forward position of the controller stop  20 . This calibration is such that the contact surface region  20 C of the controller stop  20  is forwardly fixed at the exact trigger reset position. As illustrated and described earlier in  FIG. 3  the trigger reset point  44  correlates with the most forward position of the surface region  20 C of controller stop  20 . 
     In further detail still referring to  FIG. 17 , the alternate expression corresponds in utility to that which has been previously taught, inclusive of the innovative method as described above incorporating isometric contraction upon the controller  14  interface applied by the firearm operator utilizing the firing hand trigger finger, as normally placed on the firearm trigger, and the innermost and/or upper-innermost region of the firing hand, including the thumb and/or inner web region of the thumb as placed on controller  14  rear region  16  and is incorporated within the present alternate expression. The utility of the present alternate expression, as well as the previous methodology and teachings, is further depicted by  FIG. 18  being diagramed and described in greater detail below. 
     Referring now to  FIG. 18 , drawing sheet  18 / 18 , wherein an alternate expression of the present novel invention is illustrated for further ease of understanding and inclusively described herein. Within the sight region of  FIG. 18  is shown  FIG. 18A  illustratively and figuratively representing an M4 and/or AR15 type firearm, having a two piece lower receiver  12  with a removable handle  31  being encompassed therein by a delineating single chain line. Handle  31  separately illustrated by enlarged views within the sight region of  FIG. 18  represented by  FIG. 18B  and  FIG. 18C  each being illustrated as if removed from the depicted  FIG. 18A  firearm and shown connected by indicating single chain line to the encompassed handle  31  region of  FIG. 18A .  FIG. 18B  and  FIG. 18C  having the same structures and mechanisms for ease of understanding however, in differentiation,  FIG. 18C  shown having a more fully transparent controller  14  region and handle  31  region in order to further illustrate the internal components of the alternate mechanism.  FIG. 18B  depicting controller  14  located in its most forward and at rest position and  FIG. 18C  shown depicting controller  14  located in its most rearward position.  FIG. 18C  illustrating mounting locations  69  being structurally integrated within the controller  14  innermost forward stop  26  lower region and arranged in order to accept the locatable controller guide pins  67  which move transversely and freely within guide pin mounting locations  68 . The indicating single reference lines should be understood to denote both mounting locations  69 , both controller guide pins  67 , and both guide pin mounting locations  68 .  FIG. 18C , as mentioned earlier, shown having the controller  14  in a most rearward position resulting from the combination of rearward pressure  42  exerted by the trigger finger upon the trigger, having the rear region of the trigger being in tangental contact with the controller rearward stop  20  surface region  20 C, and correct forward pressure  40  exerted on controller rear  16  by the upper innermost region of the firing hand of the firearm operator, not shown but easily understood by reference to earlier teachings herein. The controller forward stop  26  surface region is shown positioned rearwards from its most forward contact point with the handle rear region  30  as seen within  FIG. 18C . 
     Of course, the teachings of the present invention may be practiced otherwise than described above with alterations, modifications, and variations while continuing to be within the scope of these antecedent recitations which should be interpreted protectively and in consideration thereby sheltering the present inventive novelty within any adaptive combination exercising its utility. For instance, the most forward and/or most rearward movement of the interactive controller mechanism may be defined or delineated by other and/or alternate structural modifications than those illustrated herein including but not limited to; interchangeable controller mechanisms, various internal and/or adjustable interactive modular elements, automatically adjustable interfacing controller(s) and or modular elements which adaptively interact with a variety of trigger mechanisms either externally and/or internally, for example, within the trigger housing and/or firearm receiver region and/or any variation of the novel invention requiring adaptations or modifications to the handle region, trigger mechanism, and/or frame of the specific make, model, and type of firearm while continuing to maintain the utility, system, and/or modus operandi of the present invention.
