     3. Description of the Related Art 
     Firearms are mostly utilized by law enforcement, sport enthusiasts, and private owners for target and game. While participating in sport or especially during moments of self defense, it is desirable to discharge the firearm with minimal trigger travel distance and obstructions to allow for quick firing and rapid succession. In addition to rapid firing, precision shooting is an aim that is strived for. 
     In most semi-automatic firearms that have an enclosed striker assembly, as the trigger is pulled, the trigger bar slidably travels generally in a rearward and downward direction establishing undesired trigger pull excess travel. In addition, as the trigger bar slidably travels generally in the rearward and downward direction, it makes contact with a lip designed to contain the trigger bar. The lip, being an obstruction, causes a user to exert a second force to overcome the obstruction after exerting an initial force to pull the trigger. Thus, resulting in a reduction of accuracy and precision when firing. 
     There are no similar enhanced trigger control connectors to the best of applicant&#39;s knowledge that are built-in the firearms to prevent undesired trigger pull excess travel while minimizing trigger bar obstruction. 
     SUMMARY OF THE INVENTION 
     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. 
     It is therefore one of the main objects of the present invention to provide an enhanced trigger control connector for firearms utilized to correct a trigger bar obstruction. 
     It is another object of the present invention to provide an enhanced trigger control 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 undesired trigger pull excess travel. 
     It is another object of the present invention to provide an enhanced trigger control connector for firearms 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 increase the speed of firing a firearm with a reduced trigger travel distance. 
     It is another object of the present invention to provide an enhanced trigger control connector for firearms utilized with semi-automatic pistols that have an enclosed striker assembly. 
     It is yet another object of this invention to provide such a device 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, where the present invention is generally referred to with numeral  10 , it can be observed that it basically includes enhanced trigger control connector  20 , bent at predetermined locations to permit its mechanical transactions to effectuate a trigger control connector mechanism for minimizing trigger pull excess travel 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 A. Angle A 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 A from connector leg  26 ′. Angle A is approximately 90 degrees. Opposite in direction from connector lips  24 ′ and  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   , connector lip  24 ′ serves to guide curved end  50 . However, due to its position and angle A, connector 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 enhanced trigger control connector  120 . Torso  121  has guide angle  124  at predetermined angle B that is approximately between 68 degrees and 78 degrees; and in a preferred embodiment is approximately 75 degrees. Guide angle  124  serves to contain trigger bar TB when biased against it. Torso  121  also has debris slot  136 . Connector leg  126  extends from torso  121  at a predetermined angle and has disconnector tab, also defined as a reset tab,  128 . It is noted that disconnector tab  128  is located at a predetermined positioned forward and elevated as compared to connector lip  28 ′ and is at predetermined angle C. Predetermined angle C is approximately between 81 degrees and 91 degrees; and in a preferred embodiment is approximately 86 degrees. Extending from connector leg  126  is control tab  130 . Approximately opposite in direction from guide angle  124  and disconnector tab  128  is connector leg  122 .  FIG. 3 a    illustrates trigger bar TB secured onto trigger housing TH. Connector leg  122  removably fits within firearm F, seen in  FIG. 4 , to remain secured. 
     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  121 . It is noted that guide angle  124  is located at a predetermined positioned forward and elevated as compared to connector lip  24 ′ and has predetermined angle B to contain trigger bar TB when biased against it. 
     More specifically, guide angle  124  is positioned at a predetermined angle B, whereby curved end  50  of trigger bar TB nearly contacts, or contacts, guide angle  124  when firearm F is in the rest position, as illustrated, to eliminate undesired trigger pull obstruction and to minimize trigger pull excess travel when trigger T is pulled. 
     In a preferred embodiment, nearly contacts is 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 angle  124  serves to guide curved end  50  with no obstruction. The no obstruction is achieved with predetermined angle B for guide angle  124 , 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  121  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  130 . Control tab  130  is designed as a specific contact to prevent over-travel of trigger bar TB when operating in cooperation with trigger T of firearm F, and a spring force, not shown, causes trigger bar TB to shift. Guided by disconnector tab  128 , edge  52  of trigger bar TB then slidably travels generally in a forward and upward direction until completing the operating cycle. Control tab  130  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 in  FIG. 4 . Debris slot  136  is designed to minimize debris accumulation between trigger bar TB and enhanced trigger control connector  120 . 
     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  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. Disconnector tab  128  is cammed inwardly by lobe L until a spring force, not shown, causes trigger bar TB to shift. Edge  52  of trigger bar TB slidably travels generally in a forward and upward direction. Lobe L defines a ramped surface that cams disconnector tab  128  while cycling until completing the operating cycle with minimal obstruction. The minimal obstruction is achieved with enhanced disconnector tab  128  position, minimizing torsion forces upon enhanced trigger control connector  120  while cycling. Thus, resulting in improved stability and durability. 
     Enhanced trigger control connector  120  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, enhanced trigger control connector  120  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.
