Abstract

To prevent inertial forces from inadvertently releasing the slide of a semi-automatic pistol into battery, a slide stop retention mechanism is mounted on the frame. A finger extends from the mechanism and pivots under the force of a biasing spring into engagement with the slide stop when the slide is in the open position. The finger supports the slide stop. A force applied to the slide stop, either manually or via a cam on the slide when the slide is pulled back and released, will move the finger out of its supporting position and allow the slide to move to battery.

First claim

What is claimed is:

1. A pistol, comprising:
a frame;
a slide mounted on said frame, said slide being reciprocably movable relatively to said frame between an open position and a battery position;
a catch positioned in said slide;
a slide stop movably mounted on said frame, said slide stop being movable into engagement with said catch to hold said slide in said open position, said slide stop being movable out of engagement with said catch to release said slide for movement into said battery position;
a housing having a base for mounting said housing on said pistol, a back wall extending transversely to said base, a sidewall contiguous with said back wall extending substantially parallel to said base, a cavity positioned within said sidewall in spaced relation away from said back wall;
a body movably mounted on said housing, said body comprising a finger having a first end positioned adjacent to said cavity and a second end extending outwardly from said housing, a lobe mounted on said first end of said finger extending transversely thereto, said lobe being received within said cavity;
a spring positioned within said housing acting between said back wall and said first end of said finger for biasing said body to a position angularly away from said base for engagement of said body with said slide stop so as to hold said slide stop in a position of engagement with said slide, said body being movable toward said base to release said slide stop and permit disengagement of said slide stop from said slide.

2. The pistol according to claim 1 , wherein said spring comprises a coil spring.

3. The pistol according to claim 1 , wherein said finger has a contact surface on said second end thereof, said contact surface being angularly oriented relatively to said frame, said contact surface engaging said slide stop when said finger is biased angularly away from said frame.
