A main functional region () is between said impact base () and a rear end face () of said breech device. At least one percussion member () for firing a cartridge and also a surface of a cartridge slide () are in the main functional region (). The surface of the cartridge slide () is adapted to abut cartridges mounted in a magazine () in a neutral position of the breech device.

Breech device having an internally mounted functional member

In a trigger system () comprising a hammer () for firing a cartridge, a striker () adapted to accelerate the hammer (), and a sear () for releasably locking the striker (), which sear () can be unlocked by means of a release device () capable of being actuated by means of a trigger bar () that can be moved by a trigger (), wherein a front surface () of the striker rests against an end face () of the hammer for the purpose of accelerating the hammer () to initiate firing, protection of the cocked hammer () from external mechanical influences is made possible by mounting the hammer (), the striker (), the release device (), and also a main spring () adapted to accelerate the striker () for rotation about a common principal axis ().

Trigger system

A fire arm, especially a small caliber pistol, having a grip, a frame connected to the grip, a barrel unit fixed on the frame in the operating state of the fire arm, with a barrel tube and a bolt which can move relative to the frame and barrel unit such that when a shot is fired it can move to the rear against the direction of firing, the barrel unit and/or the frame having fastening means which allow detachable mounting of the barrel unit on the frame.
