Extreme Engineering Ignition Kit – Marine Corps Spur Hammer – 3-Piece Set
A Proven Trigger Upgrade for the 1911
The Extreme Engineering Marine Corps Ignition Kit upgrades your 1911 trigger with strength and control in mind. It delivers a clean break, a positive reset, and dependable performance. As a result, your pistol feels smoother, more predictable, and easier to manage.
Strong Materials, Exact Fit
First, Extreme Engineering uses advanced aerospace-grade tool steel. This is the same alloy used in rocket engines. Because of this, the parts resist wear and keep their shape under hard use.
Next, CNC machines cut each part to exact size. Therefore, the engagement surfaces come correct from the start. In turn, you do not need to stone or polish critical areas.
What Comes in the Kit
Marine Corps Spur Hammer
First, the Marine Corps Spur Hammer delivers a solid, traditional feel. Its spur design offers positive thumb control for manual cocking.
At the same time, the hammer features correct hook geometry. As a result, the trigger break stays clean and repeatable. The added mass also promotes reliable ignition, even with duty ammunition.
Marine Corp Sear
Next, the Marine Corp Sear improves smoothness. Its contoured leg reduces drag on the sear spring. Therefore, the sear moves freely and resets cleanly.
In addition, Extreme Engineering heat treats the sear to Rc 50–53. Because of this, it delivers long life and stable engagement.
National Match Disconnector
Then, the National Match Disconnector speeds up trigger reset. Its reduced weight allows fast movement during cycling.
As a result, the trigger reconnects cleanly during rapid fire and controlled pairs.
