Abstract

Various examples of a modular trigger control unit for firearms are described. The trigger control unit can be removably installed on a grip frame and installed between the grip frame and a slide assembly of a semi-automatic firearm. The trigger control unit includes at least a trigger pin and a trigger pivotable around the trigger pin when pulled. In response to the trigger being pulled by a user when the trigger control unit is installed between the grip frame and the slide assembly, a firing pin lug of a striker-firing mechanism in the slide assembly is released thereby allowing a striker of the striker-firing mechanism to move forward with respect to the slide assembly. Moreover, the trigger control unit is secured to the grip frame at least by the trigger pin such that removal of the trigger control unit from the grip frame requires removal of the trigger pin.

First claim

What is claimed is:

1. A device, comprising:
a trigger control unit configured to be removably installed on a grip frame of a semi-automatic firearm and installed between the grip frame and a slide assembly of the semi-automatic firearm, the trigger control unit comprising at least:
a trigger pin; and
a trigger pivotable around the trigger pin when pulled,

wherein, responsive to the trigger being pulled by a user when the trigger control unit is installed between the grip frame and the slide assembly, a firing pin lug of a striker-firing mechanism in the slide assembly is released thereby allowing a striker of the striker-firing mechanism to move forward with respect to the slide assembly,
wherein the trigger control unit is secured to the grip frame at least by the trigger pin such that removal of the trigger control unit from the grip frame requires removal of the trigger pin, and
wherein a serial number of the firearm is displayed on the trigger control unit.

2. The device of claim 1 , wherein the trigger control unit further comprises:
a trigger mechanism housing; and
a trigger bar coupled between the trigger and the trigger mechanism housing,
wherein, responsive to the trigger being pulled by the user when the trigger control unit is installed between the grip frame and the slide assembly, the trigger bar causes a sear in the trigger mechanism housing to lower relative to the slide assembly such that the firing pin lug is released.

3. The device of claim 2 , wherein the trigger control unit further comprises:
a support frame having a first distal end and a second distal end opposite the first distal end,
wherein the trigger is pivotably coupled to the first distal end of the support frame with the trigger pin traversing through the trigger and the first distal end of the support frame, and
wherein the trigger mechanism housing is coupled to the second distal end of the support frame.

4. The device of claim 3 , wherein the support frame is made of a polymeric material, metal or a composite of metal and polymer.

5. The device of claim 3 , wherein the trigger control unit further comprises:
a pair of slide rails extending forward from the support frame with respect to the firearm.

6. The device of claim 1 , wherein the trigger control unit is configured to be removably installed on each of a plurality of grip frames and installed between each of the plurality of grip frames and each of a plurality of slide assemblies such that:
at least two of the plurality of grip frames have different sizes, different colors, or different sizes and colors, or
at least two of the plurality of slide assemblies have different sizes, different colors, different calibers, or any combination thereof.

7. A firearm, comprising:
a grip frame;
a slide assembly containing a striker-firing mechanism therein; and
a trigger control unit configured to be removably installed on the grip frame and installed between the grip frame and the slide assembly, the trigger control unit comprising at least:
a trigger pin; and
a trigger pivotable around the trigger pin when pulled,

wherein, responsive to the trigger being pulled by a user when the trigger control unit is installed between the grip frame and the slide assembly, a firing pin lug of the striker-firing mechanism in the slide assembly is released thereby allowing a striker of the striker-firing mechanism to move forward with respect to the slide assembly, and
wherein the trigger control unit is secured to the grip frame at least by the trigger pin such that removal of the trigger control unit from the grip frame requires removal of the trigger pin, and
wherein a serial number of the firearm is displayed on the trigger control unit.

8. The firearm of claim 7 , wherein the trigger control unit further comprises:
a trigger mechanism housing; and
a trigger bar coupled between the trigger and the trigger mechanism housing,
wherein, responsive to the trigger being pulled by the user when the trigger control unit is installed between the grip frame and the slide assembly, the trigger bar causes a sear in the trigger mechanism housing to lower relative to the slide assembly such that the firing pin lug is released.

9. The firearm of claim 8 , wherein the trigger control unit further comprises:
a support frame having a first distal end and a second distal end opposite the first distal end,
wherein the trigger is pivotably coupled to the first distal end of the support frame with the trigger pin traversing through the trigger and the first distal end of the support frame, and
wherein the trigger mechanism housing is coupled to the second distal end of the support frame.

10. The firearm of claim 9 , wherein the support frame is made of a polymeric material, metal or a composite of metal and polymer.

11. The firearm of claim 9 , wherein the trigger control unit further comprises:
a pair of slide rails extending forward from the support frame with respect to the firearm.
