Abstract: A hand firearm, such as an automatic pistol, has a butt or handle in which a magazine is mounted. The magazine is retained in position by a locking member which can be actuated from either side of the pistol by the hand of the user holding the firearm. The locking member is a spring-loaded lever which has a projection received in an opening in the wall of the magazine to lock the magazine in position. An actuating member extends on both sides of the firearm and is operatively connected with the locking lever so that actuation of the actuating element will pivot the lever to unlock the magazine.

Abstract: A hand firearm has an axially movable firing pin which can be secured against axial displacement and a pivotable hammer which is retained in its cocked position by a safety lever. Upon actuation of the trigger a trigger arm first engages a release lever to disengage the firing pin from axial securement and subsequently engages the safety lever to release the safety lever from the hammer so that the hammer under the action of a spring moves from its cocked position to the firing position. The free end of the trigger arm is provided with longitudinally and laterally mutually offset abutments which sequentially engage the release lever and then the safety lever.
