ABSTRACT:
A gas-fired gun having a handgrip defining a chamber for receiving a gas-containing cartridge and a lever coupled to the handgrip at its lower end for pivotal movement between positions opening and closing the chamber. The lower end of the lever carries a seat on opposite sides of which are first and second cam surfaces. The first cam surface cams the cartridge into an operative position in the chamber with its upper end in engagement with a cartridge piercing mechanism upon movement of the lever from the first to the second position. The seat enables the cartridge to back off the piercing mechanism when the lever is in the second position to improve the gas flow from the cartridge into the gas-fired gun. The second cam surface displaces the cartridge from the chamber upon movement of the lever from the second position toward its first position. A limit surface, forming part of the flat lower end of the handgrip, abuts a limit shoulder on the handgrip body to prevent movement of the lever in a direction away from the grip past its first position.
