Abstract
A firing mechanism which allows a reduction in the overall length of a handgun by making use of space longitudinally forward of the breechface, beneath the barrel. The firing element is longitudinally slidable and has a projection which cooperates with a firing pin. A rebound spring acts on the projection and allows compatibility with a self cocking trigger. The required longitudinal space is further reduced by a longitudinal aperture through the firing element which allows the firing element to pass over the front of the driving spring guide.
Claims20
In a firearm having a frame;
- a firing mechanism comprising:
- a. a firing element having a radial projection which abuts on a firing pin;
- b. said radial projection being located substantially toward the rear of said firing element;
- c. a firing element driving spring which extends into said firing element from the rear;
- d. a guide rod which extends into said firing element driving spring, said guide rod having greater length than said firing element;
- e. a longitudinal through hole in said firing element which said guide rod may pass through;
- characterized in that said firing element is longitudinally slidable relative to said frame and relative to said guide rod.

In a standing breech firearm having a trigger;
- a firing mechanism comprising:
- a. a slidable firing element having a sear catch and a plurality of longitudinal through holes;
- b. said firing element having a radial projection which abuts on a firing pin;
- c. said radial projection providing said firing element with a substantially L shaped appearance;
- d. a firing element driving spring capable of storing potential energy for propelling said firing element;
- characterized in that rearward trigger motion is capable of increasing the load of said firing element driving spring.

In a firearm;
- a firing mechanism comprising:
- a. a slidable firing element having a sear catch and a radial projection;
- b. said radial projection being located substantially toward the rear of said firing element;
- c. a firing element driving spring capable of storing potential energy for propelling said firing element toward a position which results in firing;
- d. means for rebounding said firing element away from said position which results in firing;
- e. the rebound means incorporating a rebound spring located above said firing element driving spring;
- characterized in that said rebound means acts directly upon said radial projection.
