Abstract

A pistol has a frame, a barrel slidable on the frame and having a cartridge-receiving rear end, and a breech slidable on the frame and engageable over the rear end of the barrel to form a cartridge chamber. A standard slide carries the barrel and breech. A firing element and a firing pin operatively linked thereto are movable on the breech toward and away from the barrel between a rear position in which the firing pin is out of the cartridge chamber and a front position with the firing pin projecting forward into the cartridge chamber for firing a cartridge in the chamber when the firing element moves from the rear to the front position. A relatively strong firing spring braced against the firing element urges same into the front position and a relatively weak spring braced against the firing element urges same into the rear position. A trigger movable on the frame between an actuated and an unactuated position and an abutment engageable with the firing element and displaceable backward on the frame are linked together so as to displace the firing element back into the rear position on displacement of the trigger from the unactuated to the actuated position and to displace the abutment out of operative engagement with the firing element on displacement of the trigger into the actuated position for displacement of the firing element by the springs into the front position.

Claims6

Dependent claims

In a pistol, including

a frame having a longitudinal axis and a barrel mounted in the frame;
a slide mounted on the frame so as to be slidable forwardly toward the barrel into a closed position in which the slide is in contact with the barrel, and rearwardly out of a closed position, a recoil spring for biasing the slide into the closed position;
the slide including a breech block, the breech block closing off a cartridge chamber in the closed position of the slide;
a firing pin being mounted longitudinally movable in the breech block and having a nose projecting toward the frame, a firing pin spring for biasing the firing pin, the tension of the firing pin spring being releasable in a direction toward the barrel;
the frame further including a trigger mechanism with a trigger means and an abutment, the abutment being movable by the trigger means from an initial position initially parallel to the firing pin so that the firing pin nose engages the abutment and is moved and the firing pin spring is tensioned, the abutment being further movable in release direction until the abutment and the nose are disengaged;
the slide defining control means which during firing cause the abutment to be moved from the released position into the path of movement of the nose;
the improvement comprising,
the frame including positive guide means serving for maintaining the abutment in the path of motion of the nose of the firing pin at least in a portion of the initial movement of the abutment parallel to the firing pin.
