Abstract

A firearm breech device (100) has a breech body (110) with a lower part with functional elements for interaction with an upper part of a handle part of the firearm. A firing pin (130) is linearly movable within a bore (120) of the breech body (110) with a leading end face (111) adjacent to the cartridge chamber (200) of a barrel of the firearm. The firing pin can be propelled by means of a pulse generator (140) which is also linearly movable within the bore (120) from a retracted basic position into an advanced firing position. In the advanced firing position, an ignition pin (138) of the firing pin (130) strikes an ignition element of a cartridge (300) to fire a shot.
