Abstract

Provided herein are an ambidextrous thumb safety and apparatuses for providing the same for a handgun. The ambidextrous thumb safety and apparatuses generally comprise right and left thumb safeties pivotally mounted in opposition to a handgun frame, means for pivotally interconnecting the mounted right and left thumb safeties on the handgun frame and means for initiating pivotal movement of the right and left side plates upon application of a force thereto. Particularly, a secondary pin with a threaded end extends from the sear contact surface on the right thumb safety and is connected to the left thumb safety via a screw at a counterbored hole through the left thumb safety.

Claims (30)

1. An ambidextrous thumb safety for a handgun, comprising:

a right side plate having a threaded pin engagement hole disposed therethrough counterbored at openings thereof on the inner and an outer surfaces of the right side plate;

a left side plate having a pin with a threaded end disposed on an inner surface thereof such that the threaded pin end is in alignment with the threaded pin engagement hole;

a screw engagable with the threaded pin end at the threaded pin engagement hole; and

right and left thumb pads independently disposed at the outer surface of the right and left side plates such that the right and left side plates are pivotable upon application of a force to said thumb pads.

2. The ambidextrous thumb safety of claim 1 , wherein the right-hand side plate further comprises a pin connector disposed thereon and the left-hand side plate further comprises a pin with a slotted end disposed thereon, said pin connector slottable into the slotted pin end.

3. The ambidextrous thumb safety of claim 1 , wherein the threaded pin extends from a sear contact surface disposed on an inner surface of the left side plate of the left thumb safety.

4. The ambidextrous thumb safety of claim 3 , wherein the sear contact surface has a length of about 0.350 inches to about 0.375 inches.

5. The ambidextrous thumb safety of claim 1 , wherein the right and left thumb pads each have a plurality of serrations disposed on upper surfaces thereof.

6. An apparatus for providing an ambidextrous thumb safety for a handgun, comprising:

a right thumb safety pivotally mountable to a handgun frame;

a left thumb safety pivotally mountable onto the handgun frame in opposition to the right thumb safety;

on a side plate of the right thumb safety, a threaded pin engagement hole disposed therethrough which is counterbored at openings thereof on the inner and an outer surfaces of the right side plate;

on a side plate of the left thumb safety, a pin comprising a threaded end, said pin disposed thereon such that the threaded pin end is in alignment with the threaded pin engagement hole through the handgun frame; and

a screw threadably engaging the threaded pin end through the threaded pin engagement hole.

7. The apparatus of claim 6 , further comprising:

on the side plate of the right thumb safety, a pin connector; and

on the side plate of the left thumb safety, a pin comprising a slotted end, said pin connector slotted into the slotted pin.

8. The apparatus of claim 6 , wherein the threaded pin extends from a sear contact surface disposed on an inner surface of the side plate of the left thumb safety.

9. The apparatus of claim 8 , wherein the sear contact surface has a length of about 0.350 inches to about 0.375 inches.

10. The apparatus of claim 6 , wherein the right and left thumb safeties comprise right and left thumb pads independently disposed on an outer surface thereof, said thumb pads having a plurality of serrations disposed on their upper surfaces.

11. An ambidextrous thumb safety in combination with a handgun frame, comprising:

the handgun frame;

a threaded pin engagement hole and a pin connector independently disposed on an inner surface of a right thumb safety on the handgun frame; wherein the threaded pin engagement hole is counterbored at openings thereof on the inner and an outer surfaces of the right thumb safety;

a sear contact surface having a pin with a threaded end extending therefrom and a pin comprising a slotted end independently disposed on an inner surface of a left thumb safety on the handgun frame, said threaded pin end in alignment with the threaded pin engagement point and said pin connector slotted into the slotted pin;

a screw threadably engaging the threaded pin end through the threaded pin engagement hole; and

right and left thumb pads independently disposed at the outer surface of the right and left thumb safeties.

12. The ambidextrous thumb safety and handgun frame combination of claim 11 , wherein the handgun frame comprises receiving portions for the right thumb safety and the left thumb safety, said right and left thumb safeties pivotally interconnectable upon being received through the handgun frame.

13. The ambidextrous thumb safety and handgun frame combination of claim 11 , wherein the sear contact surface has a length of about 0.350 inches to about 0.375 inches.

14. The ambidextrous thumb safety and handgun frame combination of claim 11 , wherein said thumb pads have a plurality of serrations disposed on upper surfaces thereof.
