TMC 1911 Firing Pin 45 – Stainless Steel – .090″ Tip

Thunder Mountain Custom 1911 Firing Pin – .45 ACP

Upgrade your 1911 with the Thunder Mountain Custom 1911 Firing Pin. This part gives you precision, reliability, and long-lasting performance. Thunder Mountain makes each pin from premium 416R stainless steel bar stock and machines it to exact tolerances. Then, they heat-treat the pin to strengthen it and extend its service life. You get a firing pin that works smoothly, ignites reliably, and performs consistently shot after shot.

Precision Engineering for Reliable Ignition

This firing pin weighs exactly the right amount for positive ignition with any standard .45 ACP primer. After machining, Thunder Mountain micro-polishes each pin to a mirror finish. This smooth surface reduces friction inside the slide and lets the firing pin move freely and consistently. As a result, your 1911 fires faster, cycles smoother, and delivers cleaner double taps.

The pin has a .090-inch tip. Minor fitting may be needed depending on your firearm.
