ABSTRACT:
A pistol and cartridge shaped barrel insert is described that makes use of a unique center-fire cartridge shaped barrel insert that can be used as the barrel of a pistol and as a rimfire cartridge insert for a large bore weapon. The pistol body includes a frame with an extensible nose piece that allows insertion and removal of the cartridge insert. The cartridge insert includes an internal secondary firing pin that can be actuated to fire a rimfire cartridge by a hammer on the pistol frame or by the usual hammer and center fire mechanism of a large bore weapon. A resilient pad within the insert yieldably urges the secondary firing pin away from the breech end of the barrel.
