ABSTRACT:
A firearm, comprises a gun housing having a side opening and a gun barrel supported in the housing with a projectile bore which is alignable with a cartridge chamber of a cartridge holder. The cartridge holder is mounted on a bearing member which is journaled in the housing at a position overlying the barrel. A charge handle projects out of the housing and it is guided on the bearing member and is movable relative to the bearing member to cause rotation of the bearing member with the cartridge holder in order to project the cartridge chamber out of the side opening of the housing to a cartridge ejection and loading position. In the cartridge ejection and loading position, an injector pin, which is under the force of a compression spring, is actuated to drive an ejector pin through the chamber and eject any cartridge which may still remain in the chamber as a result of a misfire. The return movement of the charge handle under an action of a compression spring causes return of the cartridge holder, with a new cartridge positioned in the chamber, and it also effects the loading of the ejector pin for the next operation.
