Tanfoglio Witness FCP

The FCP (Fast Cycling Pistol) uses a Tanfoglio polymer frame with some similar firing mechanism parts. The slide is fixed in place. The rear portion forms a standing breech and the forward part houses a fixed 4-inch barrel. The barrel has no chamber. A large port occupies the space between the standing breech and the rear of the barrel. A special 'tube chamber' containing a loaded cartridge can be inserted to fill this space, with additional loaded chambers in the magazine below. The FCP can only be fired double-action, as nothing reciprocates to cock the hammer. When the cartridge in the tube chamber is fired, some gas from that shot is diverted back to expel the spent cartridge and tube chamber.
