Abstract
A takedown lever assembly for a striker-fired handgun. The takedown lever assembly includes a takedown actuation lever operable between a firing position and a takedown position, and a safety bar operatively coupled to the takedown actuation lever. The safety bar moves longitudinally along the frame in response to moving the takedown actuation lever from the firing position to the takedown position, thereby causing the sear to disengage from the striker.
Claims25
A takedown lever assembly for a handgun, the handgun having a grip module, a frame disposed in the grip module, a barrel, a slide displaceable along the frame, and a fire control group with a sear and a striker, the takedown lever assembly comprising:
- a takedown actuation lever operable between a firing position and a takedown position;
- a safety bar operatively coupled to the takedown actuation lever, wherein the safety bar moves distally along the frame in response to moving the takedown actuation lever from the firing position to the takedown position, thereby causing the sear to disengage from the striker.
A handgun frame assembly comprising:
- a frame extending along a bore axis from a proximal frame end portion to a distal frame end portion, the frame defining an upper portion of a magazine well and a takedown pin opening extending laterally through the frame;
- a fire control assembly attached to the frame, the fire control assembly including a trigger,
- a striker movable along the bore axis between a cocked position and a firing position, and
- a sear operable between a first position and a second position, wherein the sear is configured to engage and retain the striker in the cocked position until the sear disengages from the striker due to pulling the trigger;
- a takedown actuation lever with a lever shaft extending through the takedown lever opening and having a first end portion, a second end portion, and a lever wing extending transversely from the first end portion for operation by a user, wherein the takedown actuation lever is rotatable about the lever shaft between a firing position and a takedown position;
- and
- a safety bar extending longitudinally along the frame and operationally coupled to the takedown actuation lever, the safety bar having a distal end portion and a proximal end portion, wherein moving the takedown actuation lever from the firing position to the takedown position moves the safety bar distally, thereby causing the sear to disengage from and release the striker when the striker is in the cocked position.
