Firearm comprising a trigger, a sear lever, a firing pin and a grip acting as a butt. The firearm has, as an extension of the grip (4), a skeleton frame (5) designed to accept, removably, a cartridge (6) that is able to act as a gun barrel and, conversely, the cartridge/gun barrel (6) and the skeleton frame (5) have complementary angular-indexing and locking arrangements of the 1/4-turn type. |
