Abstract
A barrel positioning spring moves a barrel in a blow-back operating pistol earwardly when the slide recoils in order to position the chamber on the barrel to receive a further cartridge with the return of the slide. This spring in a Colt(.TM.) .45 caliber pistol may be seated on the recoil spring guide rod present beneath the barrel. A removable loading ramp extension is fitted to the frame in the space between the chamber end and the next cartridge to receive such cartridge as it is being chambered by the returning slide.
