SPECS: Most 1911 handguns on the market use one of three different diameters of firing pins. Standard .45 ACP/USGI 1911 is .093”. Most Springfield Armory Pistols use .075” Current Production Wilson of all calibers and many others uses a .38 Super/9mm pin regardless of caliber of .065” diameter. If the firing pin diameter needed is unknown, check the hole size in the recoil face or measure your pin diameter to determine the caliber firing pin needed for your slide before ordering.
