Extreme Engineering 1911 Hammer – Marine Corps Spur

The Extreme Engineering Marine Corps Spur 1911 Hammer delivers rugged reliability with classic military styling. It suits duty pistols, service‑style builds, and shooters who value proven design. In addition, it emphasizes strength, control, and long service life.

First, Extreme Engineering machines this hammer from solid tool steel bar stock. They avoid MIM and cast parts. Because of this, the hammer offers excellent strength and durability. Then, they heat treat the steel to Rc 53–55, which resists wear and maintains proper geometry under heavy use.

Next, the Marine Corps–style spur profile provides positive thumb control. This wide spur allows confident manual cocking, even with gloves. At the same time, the design maintains proper mass for reliable ignition with duty ammunition.

In addition, the hammer features chamfered edges. These smooth transitions reduce stress and help prevent cracking. They also promote smooth cycling during operation. Likewise, the precise geometry supports clean and repeatable sear engagement.

Furthermore, Extreme Engineering machines the .1565″ pivot pin hole with tight tolerances. This precision improves alignment inside the frame and reduces uneven wear. Consequently, the hammer delivers consistent performance over long-term use.

Moreover, Extreme Engineering backs the Marine Corps Spur Hammer with a lifetime guarantee against breakage when left unmodified. This guarantee reflects confidence in both materials and machining quality.

Finally, the Marine Corps Spur Hammer is Made in the USA. It works well for service pistols, historical builds, and hard‑use 1911s. Proper fitting by a qualified gunsmith ensures the best results.
