1911 Firing Pin

1911 Replacement Firing Pin

The firing pin is the small rod inside a 1911 slide that the hammer strikes, driving its tip forward into the cartridge primer to fire the round. Over many rounds a pin can wear, peen or break. A worn pin can cause light strikes, where the primer is dented but does not ignite. This United Defense firing pin is a replacement part for owners and gunsmiths servicing a 1911-pattern pistol or rebuilding one from parts.

Features

• 1911-Pattern Firing Pin — Made for the 1911 design, it rides in the firing pin channel at the rear of the slide.
• Tapered Forward Shank — The body narrows gradually toward the front so the tip passes through the breech face to reach the primer.
• Rounded Striking Tip — The front end is radiused to dent the primer cleanly when the hammer drives the pin forward.
• Stepped Rear Shoulder — A raised collar near the rear gives the firing pin spring a seat to bear against, which pulls the tip back out of the breech face after each shot.
• Reduced-Diameter Rear Tip — The short nub behind the collar engages the firing pin stop, the plate at the back of the slide that holds the pin in place.
• Dark Finish — The pin has a dark, uniform finish along its full length.
• United Defense Manufacture — Produced by United Defense, a maker of replacement parts for the 1911 platform.

Fit And Installation

1911 firing pins are not universal across calibers, so check that this pin matches your pistol's chambering before ordering. The pin installs from the rear of the slide with the firing pin spring and firing pin stop. Replacing the spring at the same time is common practice. If you are unsure about fit or headspace on your pistol, have a gunsmith install it and function check the gun.
