       BACKGROUND 
       [0002]    This application is a detailed specification of U.S. Non-Provisional application No. 62/280,027 filed on Jan. 18, 2016 and titled “TRAINING PISTOL”; the disclosure of which is incorporated herein by reference in its entirety. 
         [0003]    Firearms are the great equalizer empowering the physically weak and allowing nations to empower the populace to be the ultimate checks and balances. Firearms are ingrained in United States culture embedded with the Second Amendment and exemplified by significant increase in firearms sales in recent years. 
         [0004]    The firearm is a tool, it is by itself an inert device that cannot do anything upon its own accord. The latest technological developments in firearm quality ensures the gun will not go off unless the trigger is pulled. The ergonomic design of firearms substantially ensures the trigger will not get pulled unless the finger is in that trigger guard and presses the trigger rearwardly with respect to the frame of a handgun Proficiency is inextricably intertwined with safety. The more proficient a firearm handler is the more the safe they will be. In a similar vein as driving an automobile, the more Practice, the more handling, the more situations all breeds better driving. Although driving is plagued with distraction which is a primary cause for accidents, firearms have further growth in the area of training to further increase safe handling with the firearm. Generally speaking, most shooters have tin awareness of the extreme and immediate energy a firearm can produce. This energy of course can be used for self-defense and a plurality of firearm competitions. But the firearm culture needs a practical means for training where training is accessible, convenient, inherently diagnostic. 
         [0005]    One very practical safety-related skill is keeping the finger off the trigger until ready to shoot. The patent application which is owned by the assignee U.S. Pat. No. 8,646,201 describes the first version of the very commercially successful SIRT training pistol. The application herein describes the next generation of the SIRT training pistol which are broadly defined within the claims, but one aspect of the disclosure herein is heavy emphasis on the trigger movement detector so when the firearm handler presses the trigger there is an indication as to when and, essentially, where (how far) the trigger was depressed. In one form this is an adjustable feature so as to allow for a laser to activate when the trigger is first depressed all the way to when it is fully prepped or even beyond the break point. 
         [0006]    One skill required in law enforcement and other individuals required to carry a pistol (as well of course the massive private sector and dedicated citizens that choose to carry a gun) is keeping the finger off the trigger until ready to shoot. It is unfortunately not uncommon where a shooter will place their finger on the trigger at an inappropriate time. For example, when the lights go off there is a higher probability that the firearm handler may put their finger on the trigger and “feather” the trigger almost as if they&#39;re making sure the trigger is still there. This can be very dangerous because the firearm handler can clench and have an up to twenty-pound force in the trigger finger which is more than ample to ignite the firing process. Of course the fundamental safety rules are redundant and if the gun is pointed in a safe direction the expelled round should not do harm; however, the rules are by their very nature completely redundant and an unintentional discharge in this manner is a significant breech of proper gun handling. 
         [0007]    Training has to be practical, has to be economical and not require significant resources. There are over 18,000 law enforcement departments ranging from state to federal in the United States. Most of these departments are smaller departments such as local cities and sheriff police agencies. The firearm instructor likely has other duties and obligations and budgets are always tight where training is prone to get reduced unfortunately. 
         [0008]    Therefore, having an economic solution with inert training pistols that are safe and multifaceted where in one form the training pistol can be adjusted so as the trigger will activate a laser when it is slightly touched. Therefore, for example if a police agency is doing house entry training in a stack where multiple officers are behind one another preparing to enter a room, a trainer or even the fellow officers will be able to know when one of the officers “feathers” a trigger by activation of the laser. This is particularly pronounced in low light training. Not only is the laser on but the laser beam generally pointed forward of the muzzle can indicate the general orientation of the muzzle when the trigger was pressed or even partially pressed. 
         [0009]    Therefore, as much as speed and accuracy has to be emphasized, the very fundamental training tenets of “finger off the trigger til ready to shoot” has to be ingrained in the training and technology has to support these training tenets. But in addition to the ingrained safety training within a training regimen, the raw skills of speed and accuracy, grip establishment, natural point of arm in close targets, the use of sights at further targets and knowing when to use sights, trigger control (the ability to break a shot without disturbing the muzzle). Then of course a plurality of skill sets as reloads, slide lock stimulus recognition (to be trained with live fire pistols) single hand manipulation including single hand malfunction clearances, single hand reloads, etc. Then training expands to other areas such as compromised/awkward shooting positions, prone shooting, supine prone as well as rollover prone (getting on the ground) as well as general visual awareness in ensuring there&#39;s no liabilities down range. There&#39;s so many areas to train and resources are limited. 
         [0010]    The device disclosed herein is an inert pistol designed to train a majority of these skill sets safely. Of course recoil management, slide lock stimulus and malfunction recognition and clearance are skills that have to be trained on the range. These skills require the raw kinetic energy inertia of a firing bullet to train properly and the only space to train these three skills is with a live fire tool. The remainder of the skills can be trained off the range in very high volume and very frequently. High volume (frequent) trainings is an ideal way for learning motor neuron skills. Shooting is primarily motor neuron endeavor but also a very cognitive one as well. The motor neuron skills of establishing a grip knowing when you can shoot with minimal reference to the sights by the feel of the grip and further knowing your limitations of your point shooting to know when you have to rely on the sights. This skill requires thousands upon thousands of repetitions. It is a fool&#39;s journey to only build this skill on the range. Dry firing has been around since the dawn of guns. Dry firing is simply not firing a round but going through the motion of aligning the muzzle, supporting the firearm and pulling the trigger without the boom. A live fire gun has some potential risks of a round going off. A dedicated dry fire tool aids in the safety of dry firing and further simply makes dry firing more accessible because an inert tool such as that described herein can be around the house, training room, etc. and not have the same practical legal implications as with a live fire tool (simply because a live fire gun is a serial numbered federal firearm licensed device and losing it has more implications than losing an inert tool that cannot fire a round). 
         [0011]    Therefore, the inert tool described herein has a plurality of uses. In essence, do what you do with your live fire, gun but do it dry and do it safely and do it a lot. Train the skills (noted above) throughout your day even in 10-second short trainings, unearth the deficiencies, note the impact of the shot—indicating laser and determine was it a good hit or bad hit. Did the laser move showing a trigger mechanic issue (moving the muzzle and breaking the shot) or was it a nice clean dot? Was the dot right in the target area (acceptable accuracy zone) or was it outside? The assignee is an entity dedicated to training and raising the bar of proficiency which inherently raises the safety. And one subset of training is the dedicated focus on the fundamental safety rules and ingraining these safety rules into the fabric of the training curriculum. The trigger prep indication system can be used for performance aspects of prepping the trigger at an appropriate time (that is taking the slack) as well as dedicated training segments ensuring the trigger is not pressed at all at inappropriate times. 
         [0012]    The training benefits are beyond the scope of this patent document but the preferred embodiment is described herein where of course it is understood that other forms of the broadly claimed invention can be carried out but clearly remain within the scope of the claims herein.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0030]    As shown in  FIG. 1 , there is a training pistol  20 . To aid in the description of the training pistol  20  an axis system is defined where the axis system  10  has the longitudinal access  12  which is pointed in a forward direction where the opposing direction of arrow  12  is a longitudinal forward direction. The axis indicated at  14  is a vertical axis with the arrow in direction in an upward or vertically upward direction and the opposing direction would be a downward direction. The axis to  12  and  14  is a lateral axis indicated on  FIG. 2  at  16 . The lateral axis as shown in  FIG. 2  is pointed in a left direction where the opposing direction will be a right direction. In no way are the axis indicated to be limiting the scope of invention where for example if the training pistol was upside down obviously with respect to the Earth the vertical direction is downward whereas for purpose of reference of the general components for a best current mode to create the training pistol  20  the axis system  10  is generally used to communicate the orientation of the components at preferred mode of (but not the exclusive mode) of arranging the components described herein. This document incorporates by reference patent U.S. Pat. No. 8,646,201 by the assignee which is fully incorporated by reference and a disclosure therein is intended to be a basis for any claimed subject matter as well. 
         [0031]    As shown back in  FIG. 1 , there is a frame  22 . As shown in  FIG. 3  the frame  22  has a handle region  24  and an upper region  26 . The frame  22  further has a trigger guard  28 . 
         [0032]    In one preferred form, the frame portion  22  has a grip frame  30  and a module frame  32 . In one preferred form the grip frame  30  and the module frame  32  are two separate components and the grip frame  30  has a surface defining and interior cavity  34  for the module frame to fit therein. As shown in  FIG. 4  the slide  36  is configured to fit on the frame  22 . The attachment of slide  36  to that frame portion  22  will be further described hereinafter a more detailed description of the trigger system. 
         [0033]    Referring now to  FIG. 5 , there is shown the half section of the module frame  32 . In one preferred form the module frame  32  is split into two sections for ease of assembly where the components can be laid into the right half section  32 ( a ) as shown in  FIG. 5  (whereas numeral.  32  is designated one half of the module frame in  FIG. 5 ). 
         [0034]    The trigger  40  in one form is pivotally attached at the pivot point  42 . The pivot point  42  can be attached to the module frame  32  with a pin extending there through. A pin can further extend through the grip frame  30  to aid in attaching the module frame  32  to the grip frame  30  (as seen in  FIG. 3 ) and a trigger pin  44  can provide such an attachment and can for example be a one eighth inch roll pin in one preferred form of carrying out the preferred embodiment. 
         [0035]    Referring back to  FIG. 5 , the trigger  40  has a finger engagement portion  46  which is a longitudinally forward portion of the trigger  40  and operatively configured to have the index finger of the trigger finger of a firearm handler to press there against to reposition the trigger from a forward longitudinal location to a rearward longitudinal location. In other words, in a resting state the trigger  40  is in a forward most location and is operatively configured to move in a longitudinally rearward location with respect to the frame  22 . 
         [0036]    In one form the trigger is comprised of a trigger bar  50 . The trigger bar  50  has a base region  52  where in a preferred form the base region  52  is pivotally attached to the upper portion  54  of the trigger  40 . The trigger bar  50  further has a switch activating region  56 . The trigger bar further has a disengagement surface  58  and a trigger sear  60 . The trigger sear and disengagement surface will be further described herein following a final description of the housing and the trigger assembly. 
         [0037]    In general, the trigger  40 , the trigger bar and a trigger bar spring  62  comprise a trigger assembly. In a broader scope the trigger assembly could be one integral piece such as a trigger bar that is integral or flexibly attached to a trigger  40  but in a preferred form the trigger bar is rotationally attached to the trigger and the trigger bar spring applies a torque on the trigger bar so it is biasedly engaged towards the trigger block described below. 
         [0038]    Still referring to  FIG. 5 , the trigger block  66  is movably attached to the right housing member  32 A. Now referring to  FIG. 6 , there is shown an orthogonal view of a portion of the module frame  32 . As shown in this figure the trigger block  66  is shown to fit within the channel defined by the surfaces  70  as shown in  FIG. 7 . The channel  70  in  FIG. 7  can be part of the right housing member  32 A to provide substantially linear motion of the trigger block  66 . The biasing member  72  in one form is a coil spring and can fit within a cavity within the trigger block and further fit within a cavity in the trigger break adjustment block  74 . Still referring to  FIG. 7 , it can be seen that the trigger break adjustment block  74  has a second angled surface  76 . Referring now to  FIG. 8 , there is a side view of the trigger adjustment system  23 . (Without the housing which confines and constrains the components shown in  FIG. 8 ). It can be seen in  FIG. 8  that the trigger break adjuster  80  has a first angled surface  82  that is operatively configured to engage the second angle surface  76  of the trigger break adjustment block  74 . Therefore, when the trigger break adjuster moves vertically upward the trigger break adjustment block  74  moves to the right and precompresses the biasing member  72 . The biasing member  72  generally has a trigger block end  90  and a adjustment end  92  as shown in  FIG. 8 . As noted above in a preferred form the biasing member is a helical spring and housed within the two blocks on either end. 
         [0039]    With the foregoing description in place it can be generally appreciated that the trigger break can be adjusted so as the amount of force applied to the trigger  40  at the finger engagement portion  46  can have a dramatic feel to the break of the trigger based on the precompression of the biasing member  72 . Referring now to  FIG. 6 , it can be appreciated that as the trigger  40  moves longitudinally rearward presumably by force upon the finger engagement portion  46  the trigger bar  50  will reposition longitudinally forward and as shown in  FIG. 5 , the trigger sear  60  will eventually slide up and past the block sear  67  of the trigger block  66 , and the trigger bar  50  will continue longitudinally forward where the switch activating region  56  closes the circuit and the shot indicating laser activates. 
         [0040]    Therefore a sufficient amount of the core componentrics now described to at least get an overall appreciation for the operation of the pistol of the training pistol  20 . There will now be a more general discussion of the overall components followed by further discussion of the secondary adjustment system for the trigger prep which will be described further below in  FIG. 8  and  FIG. 10 . 
         [0041]    As shown in  FIG. 5 , there&#39;s a portion of the module frame  32  where the right housing member  32 ( a ) is shown. Within this right housing member  32 ( a ) there is a shot indicating laser  100  and a trigger prep indicator  102 . One preferred form the shot indicating laser  100  has a front portion  104  and a rearward portion  106 . Set screws can be attached to the right housing member  32 ( a ) as well as the left housing member  32 ( b ) (shown in  FIG. 30 ) to adjust the rearward portion  106  of the shot indicating laser  100 . In a similar manner, a set screw at the location  108  can be used to adjust the vertical orientation of the trigger prep indicator  102 . In a preferred form the trigger prep indicator  102  is a laser. In one form the lasers are different colors such as the shot indicating laser  100  is green and the trigger prep indicator is a red laser where in other forms they are the same color such as for example both being red lasers. 
         [0042]    A spring  120  and  122  is provided to bias the lasers towards set screws to allow for adjustment thereof. As shown in  FIG. 3  the sets screws  124  and  125  are threadedly engaged to the left housing member  32 ( b ) to adjust the rearward location of the lasers rearward locations of the shot indicating laser  100  and the trigger prep indicator  102 . 
         [0043]    As shown in  FIG. 6  there is a power supply  128 . In one form the power supply  128  is a conventional battery. As shown in  FIG. 5  the power supply in one form is an electrical communication with the switch contact  130 . The switch contact  130  in one form is configured to be interposed between the switch activating region  56  of the trigger bar  50  and the contact pad  132  as shown in  FIG. 5 . Therefore it can be appreciated as shown in  FIG. 5  when the trigger bar is longitudinally forward whereas the trigger  40  is ‘pulled or pressed’ longitudinally rearward the switch activation region  56  having an electrically conductive portion of the trigger bar  50  presses the switch contact  130  to be an electrical communication with the contact pad  132 . The contact pad  132  can for example be a small piece of conductive rod such as bronze tubing and soldered to a lead such as a positive lead to the shot indicating laser  106 . The contact pad or the battery contact  140  can for example be in contact with the negative portion of the battery where the negative lead for the shot indicating laser  100  is electronically attached thereto such as by soldering. In light form the negative contact for the trigger prep indicator  102  can be soldered to the contact  140 . 
         [0044]    With the foregoing description in place there will be discussion of the trigger movement detection system  150  as shown in  FIG. 6 . In general, the trigger movement detection system  150  is configured to determine the rotation of the trigger  40  and provide a signal of some form (visual, auditory, vibration, etc.) when the trigger is at a certain rotational position with respect to the frame  22  (shown in  FIG. 3 ). As shown in  FIG. 6 , there is a trigger movement detector  152  which in one turn is a sheet of mewl that has a mounted portion  154  and a conductive end  156 . Further, a trigger movement adjuster  158  can be provided which in one form is a set screw threadedly mounted at the location  160  which is a portion of the right housing member  32 ( a ). Therefore, when the set screw presses the trigger movement detector downward the conductive end  156  moves downward closer towards the trigger movement member  162 . In one form the trigger movement  160  is mounted at location  164  and the extension portion  166  is operatively configured to touch the conductive end  156  as the trigger  40  rotates. One preferred form this conduction is by two pieces of mewl coming together but there could be optical sensors, rotational sensors etc. By having the upper portion  45  of the trigger  40  engage the trigger movement member  162 , it has been found that this is a very economical way to detect the movement of the trigger and have the movement of the trigger translate into rotation of the trigger movement No.  162  which in this case is upward where the extension portion  166  will eventually come in contact with the conductive end  156  as shown in  FIG. 6 . Therefore, it can be appreciated that the exact activation of the trigger prep indicator  102  will occur based on where the trigger movement adjuster  158  positions the conductive end  156 . In one form the conductive end  156  is positioned just hovering over the extension portion  166  so as soon as the trigger  40  is feathered (just barely touched) the current from the trigger movement No.  162  is passed to the trigger movement detector  152  which closes a circuit to the trigger prep indicator  102  whereby activating in one form a red laser. The trigger movement. No.  162  as shown in  FIG. 6  can be soldered to a wire which is then shown in  FIG. 7  where this wire  170  passes longitudinally forward and in turn is soldered to the switch contact  130 . Therefore, it can be appreciated that the trigger movement No.  162  is an electrical communication with one form of positive contact of battery (power source  128 ). 
         [0045]    With the foregoing description of the switching system for activating the shot indicator laser  100  and the trigger prep indicator  102 , there&#39;ll be a final discussion of the trigger prep adjustment system as shown in  FIGS. 10 and 11 . As shown in  FIG. 10  the trigger prep adjustment system  190  comprises a trigger engagement block (otherwise referred to as a trigger prep block)  192  and a prep adjustment block  194 . Interposed between the trigger engagement block  192  and the prep adjustment block  194  is a second biasing member  196 . As best shown in  FIG. 10  the second biasing member  196  is attached or otherwise fitted to the blocks  92  and  194 . The trigger engagement block  192  has a trigger engaging surface  198  where as shown in  FIG. 8  this trigger engagement block is there behind the shield  200  and pressing the trigger  40  longitudinally rearward (whereas the finger engagement portion  46  is rotated longitudinally forward about the pivot point  42 ). 
         [0046]    Referring back to  FIG. 10 , die prep adjustment block  194  has the angled surface  204  which is configured to engage the angled adjustment surface  208 . The angle adjustment surface  208  is part of the trigger prep adjuster  206 . In general, the trigger prep adjuster  206  is configured to move vertically upward whereas in one form a set screw with a screw head is mounted at the location  212  where the set screw is configured to remain in place but rotate and the threaded portion is configured to engage at the location  214  of the training prep adjuster  206  whereby moving the trigger prep adjuster  206  upward and downward. This upward and downward motion translates into the prep adjustment block  194  to move longitudinally forward and rearward whereby increasing the pretension on the second biasing member  196 . 
         [0047]    There can further be seen a separator  220  where the separator  220  separates the movement of the trigger prep adjuster  206  from the trigger break adjuster  80  (shown in  FIG. 8 ). As shown in  FIG. 12  the trigger break adjuster  80  is offset in a lateral direction with respect to the trigger prep adjuster  206 . The set screw to adjust the trigger prep adjuster  206  can have a head placed at the location indicated at  212  whereas a second set screw at location  213  can have the head mounted therein and the threads engage the portion  81  of the trigger break adjuster  80  to reposition the trigger break adjuster vertically upward and downward. Therefore it can be appreciated that the biasing member  72  applies pretension thereupon by adjustment of the set screw at location  213  and further the second biasing member  196  can have pretension thereupon by adjusting the set screw which is configured to be mounted at location  212  (again referring to  FIG. 12 ). Therefore it can now be appreciated that the general locations  212  and  213  are generally represented as extending through and out a surface of the grip frame  30  shown in  FIG. 13  at the locations  212 ( a ) and  213 ( a ) (again shown in the isometric view in  FIG. 13 ). Therefore a set screw can be placed therein through the locations  212 ( a ) and  213 ( a ) to adjust the trigger prep weight and the trigger break weight accordingly. This provides for external adjustments of these features of the trigger without having to remove any components. 
         [0048]    As shown in  FIG. 11  it can further be seen how the second biasing member  196  initial length can be adjusted where the trigger prep adjuster  206  is positioned longitudinally lower whereas the set screw in this case was turned clockwise to bring the trigger prep adjuster  206  vertically downward. It can be appreciated that the prep adjustment block  194  in turn was repositioned longitudinally forward whereby reducing the pretension on the second biasing member  196 . Again to reiterate the components in  FIG. 11  are positioned in the lower left portion of  FIG. 8 . 
         [0049]    With the foregoing description in place there will be some final description and discussion on other portions for fully enabling description and best mode for carrying out the invention which is broadly defined in the claims below.  FIG. 6  shows as front cap  240 . In one form the front cap binds the pieces  32 A and  32 B (see  FIG. 4 ) together and helping them stay together during assembly and disassembly. 
         [0050]    A attachment member such as a nut and bolt assembly can pass through the surface to find a new opening  242  where as shown in  FIG. 4  the rearward portion of the module frame  32  can thereby be held together. While still referring to  FIG. 4 , the slide  36  in one form can have grooves indicated at  250  where these grooves are configured to attach to the wings  252  of the frame  22 . Therefore, the slide as shown in  FIG. 14  can be repositioned vertically downwardly and the winglets  252  will engage the grooves  250  whereby when the slide is repositioned longitudinally rearward with respect to the frame  22  a pin  260  can pass there through the frame as shown in  FIG. 1  and extend through the opening  262  as shown in  FIG. 3  to lock the slide to the frame  22  (where again the frame  22  is broadly defined as the components of the module frame  32  and the frame and the grip frame  30 ). 
         [0051]    In another form, the trigger movement member can be integral with the trigger movement member  162  can be integral with the trigger bar  50  and be an electrical communication with a power source  128  whereby as the trigger bar moves forward the upper surface of the trigger movement member will engage the conductive end  156  of the trigger movement detector  152 . 
         [0052]    So in other words, the trigger movement member will be angled vertically downward so the conductive member&#39;s height can be adjusted by the trigger movement adjuster  158  to adjust when the trigger prep indicator  102  is activated (with respect to the rotation trigger  40 ). As further shown in  FIG. 13  a grip pin attachment No.  270  is operatively configured to fit within the surface to find the opening  272  and a rear grip  274  is mounted to the handle region  24 . Therefore, different sized grips can be attached to the handle region  24  depending on the shooter&#39;s sized hands or if very small hands a smaller shooter such as a small female or child can shoot without the rear grip. 
         [0053]    As further shown in  FIG. 13  the surface defining the opening at  109  is configured to have hex wrench to adjust a vertical orientation of the trigger prep indicator as shown in  FIG. 6 . 
         [0054]    Referring to  FIG. 15 , there is a switch activation region  56   a,  which is fixedly attached to the trigger bar  50   a.  The trigger bar  50   a  is attached in a similar manner at  54 , the upper portion of the trigger  40 . The trigger  40  is pivotally attached to the modular frame  32  in a similar manner as described above. Further, the trigger bar spring  62  is operatively configured to bias the trigger bar  50   a  downward (that is downward with respect to the orientation in  FIG. 15 ), whereby forcefully engaging the trigger seer  56   a  of the trigger bar  50   a  to the lock seer  67  in a similar manner as described above. 
         [0055]    The embodiment that&#39;s shown in  FIGS. 15-17  provide an alternative way of routing the electricity from power supply  120 H, which again in a preferred form, is a conventional battery such as a CR123 or a CR2 lithium-type, 3-volt battery that is configured to supply sufficient amperage and voltage to lasers. Therefore, the trigger movement member  162   a  has a location such as that near  164   a,  which is soldered to a conducted member such as wire which is fit along the channel  307 , which, in turn, is soldered to a conductive member such as a bent piece of beryllium copper or similar conductive material to form the switch contact  130 . The switch contact  130  in a preferred form is bias to engage either the positive or the negative portion of the power source/battery  128 .  FIGS. 15-17  show the battery in a configuration where the negative portion of the battery/power source  128  is in electrical communication with the switch contact  130 . 
         [0056]    Further, current such as current from the negative terminal of the power source  128  is supplied to the trigger :movement member  162   a.  The trigger movement member  162   a  is in electrical communication with the trigger movement base  59 . The trigger movement base  59  is fixedly attached to the trigger bar  50   a  in  FIGS. 15-17 . In one form, the trigger movement base  59  is a laser cut or otherwise profiled piece of metal, which, in one form, can be between 0.050 inches to 0.200 inches not for limiting the scope but just as an example of a method for manufacture). In a preferred form, the trigger movement base is about 0.100 inches in thickness and substantially planar so it can be easily laser cut from a sheet of metal, preferably some form of stainless steel. In one form, the trigger movement base  59  is integral and a part of the trigger bar  50   a  where the trigger bar  50   a  is, for example, a plastic injection piece over molded the metallic conductive trigger movement base  59 . In this one form of carrying out the embodiment, the trigger movement member  162   a  is biased downwardly toward the trigger movement base  59  to provide electrical communication therewith. Therefore, the battery/power source  128  has one of its terminals in electrical communication and constantly (in one form) charging the trigger movement base  59  with an electrical charge. 
         [0057]    The trigger movement base  59  further has a contact surface  61  where the contact surface has a slope whereby motion of the trigger bar  50   a  to the left and right (with reference to the orientation in  FIG. 15  provides a change in the vertical surface with respect to the housing. In other words, the contact surface  61  will approach and become closer to the switch contact  63  and, more specifically, the switch tip region  65 . Therefore, as the trigger bar  50   a  moves to the left as the trigger  40  is rotating, the contact surface  61 will get closer to the switch tip region  65  whereby passing current thereto where the switch contact  63  is an electrical communication with the lasers in a similar manner a s described above. 
         [0058]    Basically, instead of having an inner posed switch contact  130  as shown in  FIG. 5  where the upper portion of the switch contact  130  is between the switch activation region  56  of trigger bar  50  and the contact pad  132  (see  FIG. 5  of the previous embodiment), in the embodiment of  FIGS. 15-17 , the contact surface  56   a  as shown in  FIG. 15  is already electrically charged and as soon as the contact surface  56   a  comes in forceful engagement with the contact pad  132 , the shot indicating laser is activated. For clarification, the switch contact  63  is configured to activate the trigger prep indicator ( 102  shown in  FIG. 5 ). 
         [0059]    Referring to  FIG. 16  similar to  FIG. 15  but in a different orientation whereby the trigger  40  is partially pressed rearwardly and this figure generally shows the trigger in a “prepped” state in fact, it&#39;s just about to what is conventionally called “the trigger break” or “the break”. Directing attention to the surfaces  56   a  and  67 , it can be appreciated that these surfaces act as mutual seer surfaces and as the trigger bar  50   a  is repositioned upwardly, these surfaces  56   a  and  67  are reaching a point of disengagement and the trigger block  66  which is under force by the second biasing member  196  will dynamically and forcefully pass thereunder the trigger bar to an orientation as shown in  FIG. 17 . 
         [0060]    Referring back to  FIG. 16 , you can see that the switch tip region  65  is very close to be in electrical communication with the contact surface  61 . In one form, the orientation of the switch tip region can be adjusted up and down by way of a set screw or other biasing member generally located at  79  where the set screw could, for example, be threadedly engaged to the right housing member  32   a.  Therefore, the set screw could be accessed from the upper portion to make an adjustment for biasing the switch tip region  65  downwardly to engage the contact surface  61  at any desirable location of the trigger bar  50   a  as it repositions from right to left. Therefore, as shown in  FIG. 16  can be appreciated that the trigger take a laser (for convenience purposes is shown in  FIG. 6  at  102 ) will be activated just as die trigger  40  pushes the trigger bar  50   a  a little hit more to the left in  FIG. 16 . 
         [0061]    In one form the laser which is generally designated as a trigger prep indicator  102  in  FIG. 6  cannot only be used to activate before a trigger break but could activate after a trigger break with this embodiment as shown in  FIGS. 15-17 . Therefore in yet another form, the switch  155  in  FIG. 16  can be activated to allow electrical communication from the switch contact  63  to the trigger prep indicator  102  which is effectively now a second shot indicating laser. In one form, the upper laser which is generally the shot indicating laser noted at  100  is turned off by the switch  155  and the current is only directed to the trigger prep indicator  102  which is now a shot indicating laser. Therefore, it allows the end user to toggle between two different lasers. This configuration can be very handy because some targeting systems only activate with a certain type of laser. Therefore, if the laser indicated at  100  is green and the laser indicated at  102  is red, then we can have an orientation where the green laser is not used as a shot indicating laser but the lower red laser is. Thereby changing the switch configuration  155  to a different selector and further adjusting the switch tip region  65  upwardly by a trigger movement adjuster indicating at the location  158 , we can now have the functionality of a trigger prep indicator (using the laser/trigger prep indicator  102  along with a shot indicator  100 ). In another form, if the switch  155  does not actually turn off the shot indicating laser  100 , the end user can cover the output of the laser so it&#39;s not visible and not being shined on the target whereby only the laser  102  is hitting the target after the shooter breaks a shot. 
         [0062]    In another form either one of the lasers  100  or  102  can be infrared or any electromagnetic frequency.  FIG. 17  shows the trigger  40  fully pressed rearwardly where in this form the contact surface  36   a  is in electrical communication with the contact pad  132  whereby providing a complete circuit to an electrical communication with the contract pad  32  (in a similar manner as described above and generally shown in  FIG. 6 ).
