Abstract
A firing mechanism for a striker-fired, magazine-fed semi-automatic pistol includes a linear cam that is attached to and moves with a slide. The linear cam moves a cam follower that pivots a reset bar. The reset bar bears upon a trigger bar projection, moving the trigger bar projection out of engagement with a lower end of a sear lower arm as the slide closes. Interference between the reset bar and the trigger bar projection prevents a second pull of the trigger from releasing the sear and moving the sear to the firing position to fire a second round until the pistol is in battery, while allowing the shooter to achieve a high rate of semi-automatic fire.
Claims19
A firing mechanism for a semi-automatic pistol having a slide, the firing mechanism comprising:
- a) a trigger;
- b) a trigger bar operably attached to the trigger, the trigger bar having a configuration for a movement in a first direction upon activation of the trigger;
- c) a sear, the sear being movable by the trigger bar from a sear cocked position to a sear firing position in response to the movement of the trigger bar in the first direction, the sear being configured to release a striker to fire the pistol when the sear moves from the sear cocked position to the sear firing position in response to the movement of the trigger bar in the first direction;
- d) a linear cam, the linear cam having a cam profile, the linear cam having a configuration to reciprocate in a reciprocating movement with the slide when the pistol is fired;
- e) a cam follower, the cam follower being configured to follow the cam profile in response to the reciprocating movement of the linear cam;
- a reset bar, the reset bar being attached to the cam follower, the reset bar having a configuration to move in response to the reciprocating movement of the linear cam, the reset bar being configured to move the trigger bar in a second direction opposite to the first direction when the linear cam reciprocates and to define a limit on the movement of the trigger bar in the first direction when the linear cam reciprocates.
