TMC 1911 Firing Pin 9mm/38 Super – Stainless Steel – 25 Pack

Thunder Mountain Custom 1911 Auto Firing Pin – 9mm / .38 Super (25‑Pack)

The Thunder Mountain Custom 1911 Auto Firing Pin deliver consistent ignition, smooth operation, and exceptional durability for 9mm and .38 Super 1911 pistols. Designed for professional builders and high‑volume shooters, this 25‑pack offers premium quality with long service life.

First, Thunder Mountain Custom machines each firing pin from solid 416 stainless steel bar stock. This material provides excellent strength and corrosion resistance. Next, heat treatment to 43–45 HRC increases durability, allowing these firing pins to last many times longer than standard factory pins.

Then, each firing pin goes through an automated micro‑polishing process. As a result, the surface achieves a true mirror finish. This ultra‑smooth finish reduces friction inside the firing pin channel, promotes faster movement, and improves reliability—without the use of coatings that can wear or chip over time.

In addition, these firing pins maintain proper mass and balance. Because of this, they deliver positive ignition with all common primer types while still cycling smoothly in competition or duty pistols.

Moreover, Thunder Mountain Custom machines these firing pins to exact tolerances. Tight dimensional control ensures proper fit, consistent tip alignment, and dependable performance shot after shot.

Just as important, Thunder Mountain Custom backs every firing pin with a lifetime guarantee, reflecting confidence in both material quality and machining precision.

Important Notes on 1911 Firing Pins

Before ordering, confirm the correct firing pin size for your slide:

• Typical .45 ACP 1911 firing pin tip diameter: .095″–.096″

• Typical 9mm / .38 Super firing pin tip diameter: .065″–.070″

Additionally, not all modern 9mm or .45 slides use the same firing pin diameter. Some 9mm slides use the larger .090″ firing pin, while others require the smaller .070″ size. Therefore, always measure your existing firing pin or check the breech face hole diameter before ordering.
