A rotatable breech mechanism includes a bolt rotatably supported in a chamber housing by a bolt handle, and which in one rotated position thereof is locked to a barrel chamber sleeve and in a further rotated position thereof is unlocked from the sleeve. A spring-loaded extractor is arranged at a front end of the bolt. The extractor, in one rotated position of the bolt, grips an edge of a bottom of a sleeve of a cartridge inserted into a cartridge chamber, whereby upon a rotation of the bolt from the one position into a further position the chamber housing with the bolt 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 barrel chamber sleeve. In one rotated position of the bolt, a rear end of the pin is received in a forwardly open recess of a shoulder surface on the bolt handle, and upon a rotation of the bolt 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 bolt is movable to a rearward position.
