ABSTRACT:
Disclosed is a firing mechanism for revolvers having a firing pin and a limit pin each movable by the hammer to engage the cartridge and cooperable to limit the extent of penetration of the firing pin into the cartridge. The limit pin engages the rim of the cartridge casing substantially simultaneously as the primer cup is struck and the cartridge is fired. The extent of penetration of the firing pin into the primer cup is predetermined and does not vary between long and short cartridges. The limit pin further retains the cartridge casing in the revolver chamber initially upon firing to permit maximum radial expansion of the casing while the cartridge casing lies fully seated in the forwardmost position in the chamber. Upon postfiring rebound, the cartridge casing elastically recovers sufficiently to provide a clearance space between the walls of the casing and the cylinder chamber to prevent jamming of the casing in the chamber.
