Extreme Engineering Ignition Kit – Speed Demon II Hammer – 5-Piece Set

Premium Extreme Engineering Ignition Kit Upgrade for Match, Carry & Duty Use

Upgrade your 1911 platform with the Extreme Engineering Speed Demon II Ignition Kit, a complete 5-piece fire-control system engineered for shooters demanding an ultra-clean, crisp, and consistent trigger pull. These components are manufactured from the same advanced alloy used in rocket booster engines, offering exceptional durability, stability, and precision. Every part is CNC-crafted to exact tolerances, eliminating the need for stoning, polishing, or hand-fitting of critical engagement surfaces.

Designed for shooters who want the smoothest, cleanest trigger break while maintaining reliability for concealed carry, competition, and general range use. This ignition kit is a major upgrade for Kimber, Springfield, Colt, STI, SV, Para, and virtually all standard 1911-pattern pistols.

Included Components

• Extreme Engineering Speed Demon II Hammer

Lightweight, ultra-precise hammer with perfect hook geometry. No stoning or modifications required. Delivers a fast lock time and crisp break.

• Extreme Engineering Ultra Low Mass Sear

Built from the same premium die steel as Extreme Engineering’s Ultra Match Sear, with tensile strength of 265 KSI and yield strength of 245 KSI. Heat-treated to RC 50-53.
Features a contoured leg design that reduces friction against the sear spring, promoting:

• Smoother sear movement

• Faster reset and engagement

• Cleaner, more consistent trigger feel

• Extreme Engineering Low Mass Race Disconnector

Engineered for extremely light and fast trigger pulls. Reduced mass ensures a shorter reset time, minimizing the risk of non-reconnect failures during rapid fire and double-taps. Compatible with Kimber, Springfield, STI, SV, and Para 1911 models.

• Thunder Mountain Custom 1911/2011 Light Sear Spring (Exclusive)

Only Thunder Mountain Custom includes a Light Sear Spring specifically tuned for enhanced trigger performance. Competing kits include standard Colt-style springs not optimized for precision trigger setups.

• Thunder Mountain Custom 17 lb Wolff Mainspring

Manufactured by Wolff Precision Gunsprings for reliable primer ignition and consistent trigger feel.

• No stoning or polishing required
