A rotatable breech mechanism has a chamber which is rotatably supported in a chamber housing by a chamber handle, and which in one rotated position thereof is locked to a chamber sleeve and in a further rotated position thereof is unlocked from the chamber sleeve. A spring-loaded extractor is arranged at the front end of the chamber, which extractor, in the one rotated position of the chamber, grips in front of the edge of the bottom of the sleeve of a cartridge inserted into the cartridge chamber, whereby upon a rotation of the chamber from the one position into the further position the chamber housing with the chamber automatically carries out a movement away from the cartridge chamber during which the extractor releases the cartridge from the cartridge chamber. The chamber housing supports an axially movable pin which is supported at its front end on the chamber sleeve, in the one rotated position of the chamber, the rear end of the pin is received in a forwardly open recess of a shoulder surface on the chamber handle, and upon a rotation of the chamber out of the one position the rear end of the pin slides out of the recess onto the shoulder surface, and the chamber housing with the chamber is hereby moved rearwardly into a first position.
A rotatable breech mechanism comprising a chamber which is rotatable in a chamber housing by a chamber handle, and which is locked in the one position to a chamber sleeve and is unlocked in a further position from the chamber sleeve, comprising a spring-loaded extractor arranged at the front end of the chamber, which extractor grips in the one position of the chamber in front of the edge of the bottom of the sleeve of a cartridge set in the cartridge chamber, whereby upon a rotation of the chamber from the one position into the further position the chamber housing with the chamber automatically carries out a movement away from the cartridge chamber, during which the extractor releases the cartridge from the cartridge chamber, wherein the chamber housing supports axially movably a pin, which is supported with its front end on the chamber sleeve, in the one position of the chamber the rear end of the pin engages a forwardly open recess of a shoulder surface on the chamber handle, and upon a rotation of the chamber from the one position the rear end of the pin slides out of the recess onto the shoulder surface, and the chamber housing with the chamber is hereby moved to the rear into a first position.
