TMC C4V‑TiN Titanium 1911 Firing Pin – .45 ACP

Upgrade your 1911 with the TMC C4V‑TiN Titanium 1911 Firing Pin. Designed for .45 ACP, this part improves lock time, trigger response, and overall performance. By combining lightweight titanium with a C4V (TiN) coating, it outperforms standard steel or stainless pins in speed, durability, and reliability.

Lightweight Titanium Reduces Lock Time

Each firing pin is precision-machined from high-grade titanium bar stock. Because it weighs 40–45% less than steel, your 1911 experiences faster lock time, quicker double taps, and smoother trigger response. Therefore, it is perfect for competition shooters and high-performance builds.

C4V (TiN) Coating Boosts Durability

After machining, the pin is heat-treated and coated with C4V (TiN). This coating provides:

• Hardness of 2600 Vickers for excellent wear resistance

• Ultra-low friction coefficient of 0.4 for smoother cycling

• Thin 2-micron layer to maintain precise fit

As a result, the pin runs smoothly, stays reliable, and cleans easily even after thousands of rounds.

Strong, Reliable Design

The combination of lightweight titanium and hard C4V coating makes this firing pin faster, stronger, and more reliable. It also maintains proper function longer than standard pins. Thunder Mountain Custom backs it with a lifetime guarantee.
