Abstract: Disclosed is a magazine catch for a pistol. The catch is reversible for operation from one or the other side of the pistol to release the magazine from the pistol. The catch includes a pin carrying a pair of projections. One of the projections engages a slot in the side of the magazine to retain the magazine in the pistol handle. The pin has a radially offset chamber which receives a locking screw. A spring in the chamber biases the screw and the pin axially away from one another. The screw carries a locking cam which projects through a slot in the pin for engagement in a locking grooves carried by the seat. By pressing the button on the end of the pin, the projection is displaced from the magazine slot to release the magazine. To operate the magazine catch from the opposite side of the pistol, the locking screw is rotated to withdraw the locking cam from the locking grooves. The catch is then axially removed from its seat, reversed in orientation, and inserted into the seat from the opposite of the pistol.
