     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to firearm trigger connectors, and more particularly, to firearm enhancing trigger connectors. 
     Description of the Related Art 
     Applicant believes that one of the closest references corresponds to Applicant&#39;s own U.S. Pat. No. 9,062,925 issued to Arthur Viani on Jun. 23, 2015 for Enhanced trigger control connector. However, it differs from the present invention because Viani teaches a firearm enhanced trigger control connector. A torso has a guide angle positioned at a first predetermined angle. The guide angle contains a trigger bar of a firearm. The torso further has a first connector leg extending therefrom at a second predetermined angle. The first connector leg has a disconnector tab at a third predetermined angle. Extending from the first connector leg is a control tab. The torso further has a second connector leg that removably fits within a trigger housing of the firearm. 
     Applicant believes that another reference corresponds to Applicant&#39;s own U.S. Pat. No. 9,410,758 issued to Arthur Viani on Aug. 9, 2016 for Enhanced trigger control connector. However, it differs from the present invention because Viani teaches a firearm enhanced trigger control connector. A torso has a guide angle positioned at a first predetermined angle. The guide angle contains a trigger bar of a firearm. The torso further has a first connector leg extending therefrom at a second predetermined angle. The first connector leg has a disconnector tab at a third predetermined angle. Extending from the first connector leg is a control tab. The torso further has a second connector leg that removably fits within a trigger housing of the firearm. 
     Applicant believes that another reference corresponds to Applicant&#39;s own U.S. Pat. No. 9,404,700 issued to Arthur Viani on Aug. 2, 2016 for Enhanced trigger control connector. However, it differs from the present invention because Viani teaches a firearm enhanced trigger control connector. A torso has a guide angle positioned at a first predetermined angle. The guide angle contains a trigger bar of a firearm. The torso further has a first connector leg extending therefrom at a second predetermined angle. The first connector leg has a disconnector tab at a third predetermined angle. Extending from the first connector leg is a control tab. The torso further has a second connector leg that removably fits within a trigger housing of the firearm. 
     Applicant believes that another reference corresponds to U.S. Pat. No. 5,822,903 issued to Sr. James Jefrey Davis, on Oct. 20, 1998 for Externally adjustable slide trigger assemblies for handguns. However, it differs from the present invention because Davis teaches an externally adjustable slide trigger assembly, which is a drop-in replacement for existing conventional slide triggers. No drilling/tapping or other handgun modifications are required. The variable adjustment range provided allows the handgun owner to change trigger-pull characteristics from a stock trigger-pull weight to a low competition trigger-pull weight in the field. Trigger slack is completely eliminated at or near competition trigger-pull weights. 
     Applicant believes that another reference corresponds to U.S. Patent Application Publication No. 20060236581 published on Oct. 26, 2006 to Applicant&#39;s own Arthur Viani for Self-cleaning trigger connector system. However, it differs from the present invention because Viani teaches a self-cleaning trigger connector system resulting in increased reliability comprising a self-cleaning trigger connector and a trigger mechanism housing. The self-cleaning trigger connector is designed with specific contact points to prevent over-travel of the trigger bar when operating in cooperation with the trigger of the firearm. The self-cleaning trigger connector has a first at least one elongated through hole of a predetermined length that allows for a lighter trigger pull and defines a lubrication reservoir. The trigger mechanism housing comprises a second at least one elongated through hole. Debris that accumulates from the interaction between the trigger bar and the self-cleaning trigger connector passes through the first and second at least one elongated through holes. After passing through the first and second at least one elongated through holes, the debris then falls downwardly through a cavity adjacent to the firearm magazine well. 
     Other patents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention. 
     SUMMARY OF THE INVENTION 
     The present invention is a firearm enhancing trigger connector, comprising a torso having first and second edges. The torso comprises a guide lip mount extending from the torso beyond the first edge at a first predetermined angle. The guide lip mount comprises a guide lip positioned at a second predetermined angle approximately 65-80 degrees with respect to the second edge. The guide lip contains a trigger bar of a firearm. The guide lip mount further comprises a control tab extending therefrom at a third predetermined angle from the first edge. The torso further comprises a first connector leg extending from the torso towards the first edge at a fourth predetermined angle. The first connector leg has a reset tab at a fifth predetermined angle approximately 85-95 degrees with respect to the first connector leg. The torso further comprises a second connector leg that removably fits within a trigger housing of the firearm. 
     The trigger bar nearly contacts or contacts the guide lip when the firearm is in a rest position. The torso further comprises an elongated debris slot designed to minimize debris accumulation. The guide lip mount extends from the torso beyond the first edge a first predetermined distance, and the first connector leg extends from the torso beyond the first edge a second predetermined distance. The first predetermined distance is greater than the second predetermined distance. The first connector leg extends from the second edge. The reset tab is positioned over the guide lip. The guide lip is closer to the second connector leg than the reset tab. The first connector leg defines a sixth predetermined angle with respect to the guide lip, wherein the sixth predetermined angle is less than 90 degrees. The guide lip contains the trigger bar of the firearm when biased against the guide lip. 
     The trigger bar is biased against the torso when the firearm is in the rest position. The nearly contacts is a distance up to approximately 3 mm. As a trigger is pulled, the trigger bar slidably travels generally in a rearward and downward direction and the guide lip serves to guide an end of the trigger bar with no obstruction. The no obstruction is achieved with the second predetermined angle for the guide lip, saving a user from exerting a second force after exerting an initial force to pull the trigger. 
     After a point of firing, the trigger bar continues to travel generally in a rearward and downward direction until a cross edge contacts the control tab. A lobe cams the reset tab while cycling until completing an operating cycle with minimal obstruction. The minimal obstruction is achieved with the fifth predetermined angle of the reset tab, minimizing torsion forces while the cycling occurs. 
     The second connector leg is approximately opposite in direction from the guide lip and the reset tab. The first predetermined angle is approximately 130-140 degrees, and the third predetermined angle is approximately 40-50 degrees. 
     It is therefore one of the main objects of the present invention to provide a firearm enhancing trigger connector utilized to correct a trigger bar obstruction. 
     It is another object of the present invention to provide a firearm enhancing trigger connector for firearms to minimize trigger bar obstruction while it is traveling generally in a rearward and downward direction as the trigger is pulled, defining an undesired trigger pull effort. 
     It is another object of the present invention to provide a firearm enhancing trigger connector to prevent over manipulation of the trigger, which causes a reduction of accuracy while repetitive firing. 
     It is another object of the present invention to provide a firearm enhancing trigger connector to increase the speed of firing a firearm with a reduced trigger travel distance. 
     It is another object of the present invention to provide a firearm enhancing trigger connector utilized with semi-automatic pistols that have an enclosed striker assembly. 
     It is yet another object of this invention to provide such a firearm enhancing trigger connector that is inexpensive to manufacture and maintain while retaining its effectiveness. 
     Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings, the present invention is generally referred to with numeral  10 . It can be observed that it basically includes firearm enhancing trigger connector  220 , bent at predetermined locations to permit its mechanical transactions to effectuate a trigger connector mechanism for minimizing trigger pull effort and torsion force effects. 
     Seen in  FIGS. 1 and 1   a  is prior art connector  20 ′. Torso  21 ′ has lip  24 ′. Lip  24 ′ serves to contain trigger bar TB when biased against it. Lip  24 ′ is at angle α. Angle α is approximately 90 degrees. Connector leg  26 ′ extends from torso  21 ′ at a predetermined angle and has connector lip  28 ′. Connector lip  28 ′ is at angle α from connector leg  26 ′. Angle α is approximately 90 degrees. Opposite in direction from lip  24 ′ and connector lip  28 ′ is connector leg  22 ′.  FIG. 1 a    illustrates trigger bar TB secured onto trigger housing TH. Connector leg  22 ′ removably fits within firearm F, seen in  FIG. 2 , to remain secured. 
     As seen in  FIG. 2 , prior art connector  20 ′ works in conjunction with trigger bar TB. While firearm F, is in the rest position, trigger bar TB is biased against torso  21 ′. As trigger T is pulled, trigger bar TB slidably travels generally in a rearward and downward direction establishing undesired trigger pull excess travel. 
     As seen in  FIG. 2 a   , lip  24 ′ serves to guide curved end  50 . However, due to its position and angle A, lip  24 ′ also is an obstruction. This obstruction causes a user to exert a second force to overcome the obstruction after exerting an initial force to pull trigger T. Thus, resulting in a reduction of accuracy and precision when firing. Trigger bar TB remains biased against torso  21 ′ at the point of firing. 
     As seen in  FIG. 2 b   , after the point of firing, trigger bar TB continuous to travel generally in a rearward and downward direction until a spring force, not shown, causes trigger bar TB to shift. Guided by connector lip  28 ′, edge  52  of trigger bar TB slidably travels generally in a forward and upward direction until completing the operating cycle. 
     Seen in  FIGS. 3 and 3   a  is the present invention, defined as firearm enhancing trigger connector  220 . As seen in  FIG. 3 , firearm enhancing trigger connector  220  has torso  221  having first and second edges  234  and  236  respectively. Torso  221  has guide lip mount  232  extending beyond first edge  234  at a first predetermined angle A approximately 130-140 degrees. In a preferred embodiment, angle A is approximately 134 degrees. Guide lip mount  232  comprises guide lip  224  positioned at a second predetermined angle B approximately 65-80 degrees with respect to second edge  236 . In a preferred embodiment, the second predetermined angle B is approximately 77 degrees. Guide lip  224  contains trigger bar TB of firearm F, seen in  FIG. 4 . 
     Guide lip mount  232  further comprises control tab  240  extending therefrom at a third predetermined angle C approximately 40-50 degrees from first edge  234 . In a preferred embodiment, the third predetermined angle C is approximately 44 degrees. Torso  221  further comprises first connector leg  226  extending from torso  221  towards first edge  234  at a fourth predetermined angle. First connector leg  226  has reset tab  228  at a fifth predetermined angle E approximately 85-95 degrees with respect to first connector leg  226 . In a preferred embodiment, fifth predetermined angle E is approximately 90 degrees. Approximately opposite in direction from guide lip  224  and reset tab  228  is connector leg  222 . Torso  221  further comprises elongated debris slot  238 . In a preferred embodiment, elongated debris slot  238  extends along of approximately a first half of torso  221 . Elongated debris slot  238  is designed to minimize debris accumulation between trigger bar TB, seen in  FIG. 3A , and firearm enhanced trigger connector  220 . 
     Guide lip mount  232  extends from torso  221  beyond first edge  234  a first predetermined distance and first connector leg  226  extends from torso  221  beyond first edge  234  a second predetermined distance, wherein the first predetermined distance is greater than the second predetermined distance. 
     First connector leg  226  extends from second edge  236 , whereby it defines a corner as it extends from second edge  236 . Reset tab  228  is positioned over guide lip  224 , and guide lip  224  is closer to second connector leg  222  than reset tab  228 , whereby a distance from reset tab  228  to connector leg  222  is longer than a distance from guide lip  224  to connector leg  222 . In addition, first connector leg  226  defines a sixth predetermined angle D with respect to guide lip  224 , wherein the sixth predetermined angle D is less than 90 degrees. In a preferred embodiment sixth predetermined angle D is approximately 50-60 degrees, and more specifically approximately 56 degrees. 
       FIG. 3 a    illustrates trigger bar TB secured onto trigger housing TH. Second connector leg  222  removably fits within trigger housing TH of firearm F, as seen in  FIG. 4 , to remain secured. Guide lip  224  serves to contain trigger bar TB when biased against it. Trigger bar TB nearly contacts or contacts guide lip  224  when firearm F, seen in  FIG. 4 , is in a rest position. 
     Control tab  240  is designed as a specific contact to prevent over-travel of trigger bar TB when operating in cooperation with trigger T, and a spring force, not shown, causes trigger bar TB to shift. 
     The conventional placement of guide lip  224  and reset tab  228  is reversed from the prior art. Changing their placement creates the smoothest trigger pull possible. Thus, providing a mechanical advantage with present invention  10 . 
     As seen in  FIG. 4 , firearm F is in the rest position. Once a user grasps firearm F, aims, and is ready to fire, the user exerts a force to overcome the force of trigger T. Trigger T is mechanically connected to trigger bar TB. In the rest position, trigger bar TB is biased against torso  221 . It is noted that guide lip  224  is located at a predetermined positioned forward and elevated as compared to lip  24 ′, seen in  FIG. 1 , and has a predetermined angle B, seen in  FIG. 3 , to contain trigger bar TB when biased against it. 
     More specifically, guide lip  224  is positioned at the predetermined angle B, seen in  FIG. 3 , whereby curved end  50  of trigger bar TB nearly contacts, or contacts, guide lip  224  when firearm F is in the rest position, as illustrated, to eliminate undesired trigger pull obstruction and to minimize trigger pull effort when trigger T is pulled. In a preferred embodiment, nearly contacts are defined as a distance up to approximately 3 mm. 
     As trigger T is pulled, trigger bar TB slidably travels generally in a rearward and downward direction and guide lip  224  serves to guide curved end  50  with no obstruction. The no obstruction is achieved with the predetermined angle B for guide lip  224 , saving the user from exerting a second force after exerting an initial force to pull trigger T. Thus, resulting in improved accuracy and precision when firing. Trigger bar TB remains biased against torso  221  at the point of firing. 
     As seen in  FIG. 4 a   , after the point of firing, trigger bar TB continuous to travel generally in a rearward and downward direction. Cross edge  60  contacts control tab  240 . Guided by reset tab  228 , edge  52  of trigger bar TB then slidably travels generally in a forward and upward direction until completing the operating cycle. Control tab  240  establishes a shortened trigger travel distance. With a shortened trigger travel distance, less time is required for the user to discharge firearm F. As a result, the user benefits from each subsequent discharge with less time required for firearm F to cycle back into the rest position, as seen in  FIG. 4 . 
     As seen in  FIG. 5 , after the point of firing, trigger bar TB continues to travel generally in a rearward and downward direction. Connector lip  28 ′ is cammed inwardly by lobe L until a spring force, not shown, causes trigger bar TB to shift. Edge  52 , seen in  FIG. 4A , of trigger bar TB slidably travels generally in a forward and upward direction. Lobe L defines a ramped surface that cams connector lip  28 ′ while cycling until completing the operating cycle. However, due to its position, connector lip  28 ′ also is an obstruction. This obstruction causes torsion forces upon prior art connector  20 ′ while cycling. Thus, compromising the stability and durability of prior art connector  20 ′. 
     As seen in  FIG. 6 , after the point of firing, trigger bar TB continues to travel generally in a rearward and downward direction. Reset tab  228  is cammed inwardly by lobe L until a spring force, not shown, causes trigger bar TB to shift. Edge  52 , seen in  FIG. 4A , of trigger bar TB slidably travels generally in a forward and upward direction. Lobe L defines a ramped surface that cams reset tab  228  while cycling until completing the operating cycle with minimal obstruction. The minimal obstruction is achieved with the length and the fifth predetermined angle E of reset tab  228 , minimizing torsion forces upon firearm enhancing trigger connector  220  while cycling. Thus, resulting in improved stability and durability. 
     Firearm enhancing trigger connector  220  is made out of a durable and light weight material as stainless steel, alloy metal, or other material having similar characteristics. In the preferred embodiment, firearm enhancing trigger connector  220  is manufactured as a single metallic piece and have a general consistent thickness throughout of approximately 0.10 mm to 2.00 mm, so as to cooperatively interact with the general trigger mechanism of semiautomatic firearms that have an enclosed striker assembly. Such a firearm may be “GLOCK”, without limitation to this specific brand. 
     The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
