Locking device for installation in a frame assembly of a firearm, and also a frame assembly equipped therewith and a firearm equipped with the frame assembly

Abstract

A locking device for a firearm, the locking device includes a slide lock for installation in a frame assembly. On the slide lock is a first guiding part to be received in a first receiving slit of a frame of the frame assembly. Also on the slide lock is a second guiding part to be received in a second receiving slit of the frame of the frame assembly. The slide lock can be received in the frame displaceably between a locking position and an unlocking position. Further, the slide lock interacts with a barrel of the firearm such that the slide lock can be received in the frame displaceably in a transverse direction between the unlocking position and a self-holding position. Still further, the slide lock, when in the self-holding position, is secured to prevent it from being displaced of its own accord into the locking position.
