Thunder Mountain Custom 1911 Firing Pin – 9mm / .38 Super

Upgrade your 1911 with a 1911 firing pin built for accuracy, durability, and consistent ignition. The Thunder Mountain Custom 1911 Auto Firing Pin for 9mm and .38 Super delivers smooth operation, correct weight, and long service life for serious shooters.

Precision Machined for Reliable Ignition

Thunder Mountain Custom machines each firing pin from 416 stainless steel bar stock to exact tolerances. This precision ensures proper fit and dependable ignition with all primer types. Because the weight is carefully balanced, the firing pin strikes hard enough for reliability without increasing lock time.

Heat Treated for Long Service Life

After machining, each firing pin is heat treated to 43–45 HRC. This process greatly increases strength and wear resistance. As a result, the firing pin lasts many times longer than standard factory parts, even under heavy use.

Mirror-Polished for Ultra-Smooth Operation

Every firing pin goes through an automatic micro-polishing process. This creates a mirror-smooth surface that reduces friction inside the firing pin channel. Therefore, the firing pin moves freely, resists fouling, and delivers consistent performance shot after shot.

Why Choose a Thunder Mountain Custom Firing Pin?

This firing pin improves reliability in several ways. First, the stainless steel construction resists corrosion. Next, the polished surface reduces drag. Finally, the correct weight ensures positive ignition. Together, these features make it a smart upgrade for competition, duty, or range pistols.
