Abstract

A frame assembly for facilitating disassembly of a striker-fired pistol is disclosed. The frame assembly facilitates removal of the slide from a striker-fired pistol without trigger manipulation and with minimized potential for a round to be chambered. The frame assembly includes a takedown safety lever and a takedown actuation lever. Movement of the takedown safety lever causes the sear to be moved such that subsequent slide motion will not result in the storage of striker energy. Movement of the takedown safety lever is only possible while the slide is refracted beyond the point at which a chambered round would be ejected. Removal of the slide does not require pulling the trigger. The positioning of the takedown safety lever motion for disassembly may be precluded by the presence of a magazine in the gun, thereby eliminating the possibility that a round could be chambered during subsequent slide motion.

First claim

What is claimed is:

1. A frame assembly for a striker-fired pistol, comprising:
a takedown actuation lever;
a takedown safety lever operatively coupled to the takedown actuation lever, the takedown safety lever configured to be moveable with respect to a frame of the pistol between a shooting position and a takedown position responsive to manual movement of the takedown actuation lever; and
a sear tab extending laterally from the takedown safety lever, the sear tab configured to engage with a sear of the pistol and, in response to movement of the takedown safety lever, disengage the sear from a striker pin of the pistol.

2. The frame assembly of claim 1 , wherein the sear tab is configured to depress the sear downward with respect to the frame and out of engagement with a striker hook of the pistol while the takedown safety lever is in the takedown position.

3. The frame assembly of claim 1 , further comprising a cam coupled to the takedown actuation lever and configured to rotate about a lateral axis of the pistol in response to like movement of the takedown actuation lever.

4. The frame assembly of claim 3 , wherein the takedown safety lever is configured to engage the cam such that rotation of the cam causes the takedown safety lever to move longitudinally with respect to the frame.

5. The frame assembly of claim 1 , further comprising a magazine tab coupled to the takedown safety lever and configured to prevent a magazine, by mechanical interference therewith, from being installed into the pistol while the takedown safety lever is in the takedown position.

6. The frame assembly of claim 1 , wherein the sear tab is movable longitudinally with respect to the frame in response to like movement of the takedown safety lever.

7. The frame assembly of claim 1 , wherein the sear has an opening formed in one side thereof, and wherein the sear tab is further configured to engage and slide upon an inclined inner surface of the opening during movement of the takedown safety lever, thereby causing the sear to move downwardly out of engagement with a striker hook of the pistol in response to a downward depression of the sear by the sear tab.

8. The frame assembly of claim 1 , further comprising a takedown safety lever return spring operatively coupled to the takedown safety lever and configured to bias the takedown safety lever forward toward the shooting position.

9. The apparatus of claim 1 , wherein the takedown actuation lever is pivotably coupled to the frame of the pistol.

10. A frame assembly for a striker-fired pistol, comprising:
a takedown actuation lever;
a cam coupled to the takedown actuation lever and configured to rotate about a lateral axis of the pistol in response to like movement of the takedown actuation lever;
a takedown safety lever having a front portion, a mid-portion, a rear portion, the takedown safety lever configured to be moveable with respect to a frame of the pistol between a shooting position and a takedown position, the front portion configured to engage the cam such that rotation of the cam causes the takedown safety lever to move longitudinally with respect to the frame; and
a sear tab extending laterally from the rear portion of the takedown safety lever, the sear tab configured to engage with a sear of the pistol and, in response to movement of the takedown safety lever, disengage the sear from a striker pin of the pistol.

11. The frame assembly of claim 10 , wherein the sear tab is configured to depress the sear downward with respect to the frame and out of engagement with a striker hook of the pistol while the takedown safety lever is in the takedown position.

12. The frame assembly of claim 10 , further comprising a magazine tab coupled to the mid-portion of the takedown safety lever and configured to prevent a magazine, by mechanical interference therewith, from being installed into the pistol while the takedown safety lever is in the takedown position.

13. The frame assembly of claim 10 , wherein the sear tab is movable longitudinally with respect to the frame in response to like movement of the takedown safety lever.

14. The frame assembly of claim 10 , wherein the sear has an opening formed in one side thereof, and wherein the sear tab is further configured to engage and slide upon an inclined inner surface of the opening during movement of the takedown safety lever, thereby causing the sear to move downwardly out of engagement with a striker hook of the pistol in response to the downward depression of the sear by the sear tab.

15. The frame assembly of claim 10 , further comprising a takedown safety lever return spring operatively coupled to the takedown safety lever and configured to bias the takedown safety lever forward toward the shooting position.

16. The apparatus of claim 10 , wherein the takedown actuation lever is pivotably coupled to the frame of the pistol.

17. A kit comprising:
a takedown actuation lever;
a takedown safety lever configured to be operatively coupled to the takedown actuation lever and a frame of a pistol, the takedown safety lever configured to be moveable with respect to the frame between a shooting position and a takedown position responsive to manual movement of the takedown actuation lever; and
a sear tab configured to attach to and extend laterally from the takedown safety lever and engage with a sear of the pistol and, in response to movement of the takedown safety lever, disengage the sear from a striker pin of the pistol.

18. The kit of claim 17 , further comprising a cam configured to be coupled to the takedown actuation lever and to rotate about a lateral axis of the pistol in response to like movement of the takedown actuation lever.

19. The kit of claim 17 , further comprising a magazine tab configured to be coupled to the takedown safety lever and to prevent a magazine, by mechanical interference therewith, from being installed into the pistol while the takedown safety lever is in the takedown position.

20. The kit of claim 17 , wherein the sear has an opening formed in one side thereof, and wherein the sear tab is further configured to engage and slide upon an inclined inner surface of the opening during movement of the takedown safety lever, thereby causing the sear to move downwardly out of engagement with a striker hook of the pistol in response to the downward depression of the sear by the sear tab.
