Thunder Mountain Custom C4V (TiN) Titanium 1911 Firing Pin – .38 Super

Upgrade your 1911 with the Thunder Mountain Custom C4V (TiN) Coated Titanium 1911 Firing Pin for .38 Super. This precision part delivers faster lock time, smoother operation, and long service life. By combining lightweight titanium with an advanced C4V (TiN) coating, this firing pin outperforms standard steel or stainless designs.

Lightweight Titanium Improves Speed

Thunder Mountain Custom machines each firing pin from high-quality titanium bar stock. Because titanium weighs far less than steel, this firing pin is about 40–45% lighter than mil-spec stainless pins. As a result, lock time drops significantly. Therefore, trigger response improves and double taps become faster and more consistent.

Advanced C4V (TiN) Coating for Durability

After machining, each firing pin is heat treated and coated with C4V (TiN) using a PVD process. This coating is not a typical TiN finish. Instead, it provides:

• 2600 Vickers hardness for extreme wear resistance

• Low friction coefficient of 0.4 for smooth movement

• Ultra-thin 2-micron thickness to maintain precise fit

Because of this coating, the firing pin resists wear, cycles smoothly, and cleans easily. In addition, it maintains reliable performance through high round counts.

Why Choose a C4V-Coated Titanium Firing Pin?

This firing pin delivers real performance benefits. First, the lighter weight reduces lock time. Next, the hardened coating increases strength and longevity. Finally, the low-friction surface improves reliability and makes cleaning faster and easier. Best of all, Thunder Mountain Custom backs this firing pin with a lifetime guarantee.
