Extreme Engineering Ignition Kit – Speed Demon II – 5 Piece

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

Premium Ignition Upgrade for Match, Carry, and Duty Use

To begin with, the Extreme Engineering Speed Demon II Ignition Kit upgrades your 1911 with a clean, crisp, and highly consistent trigger pull. At the same time, this complete 5-piece fire-control system delivers professional-level performance for shooters who demand precision, speed, and long-term reliability.

Moreover, Extreme Engineering machines every component from the same advanced alloy used in rocket booster engines. Because of this, the kit provides exceptional strength, dimensional stability, and extended service life. In addition, CNC machining to exact tolerances removes the need for stoning, polishing, or hand-fitting of critical engagement surfaces. As a result, you gain consistent performance straight out of the box.

Furthermore, this ignition kit enhances trigger performance without sacrificing the reliability required for concealed carry, competition, duty, and routine range use. Consequently, it serves as a dramatic improvement over factory fire-control systems found in Kimber, Springfield, Colt, STI, SV, Para, and most standard 1911-pattern pistols.

Included Components

Extreme Engineering Speed Demon II Hammer

First and foremost, the Speed Demon II Hammer delivers precise hook geometry combined with reduced mass. Therefore, it produces a faster lock time and a sharp, predictable trigger break. Additionally, the hammer installs without modification, which means no stoning or polishing is required.

Extreme Engineering Ultra Low Mass Sear

Likewise, Extreme Engineering manufactures the Ultra Low Mass Sear from premium die steel with a tensile strength of 265 KSI and a yield strength of 245 KSI, then heat-treats it to RC 50–53 for optimal hardness. Furthermore, the contoured leg design reduces friction against the sear spring. Consequently, it improves sear movement, accelerates reset, and delivers a cleaner, more consistent trigger feel.

Extreme Engineering Low Mass Race Disconnector

Meanwhile, the Low Mass Race Disconnector shortens reset time and supports extremely light, fast trigger pulls. Because its reduced mass cycles more efficiently, it minimizes the risk of non-reconnect failures during rapid fire and double-tap sequences. Additionally, it remains fully compatible with Kimber, Springfield, STI, SV, and Para 1911 pistols.

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

In contrast to competing kits, Thunder Mountain Custom includes a Light Sear Spring that is specifically tuned for enhanced trigger performance. As a result, this spring improves engagement geometry, refines reset characteristics, and increases overall trigger control beyond what standard Colt-style springs can provide.

Thunder Mountain Custom 17 lb Wolff Mainspring

Finally, the included 17 lb Wolff mainspring, manufactured by Wolff Precision Gunsprings, ensures reliable primer ignition. At the same time, it maintains a smooth, consistent trigger feel across a wide range of ammunition.

Why This Kit Stands Out

• Above all, it eliminates the need for stoning or polishing

• Additionally, it supports carry, tactical, competition, and range use

• Furthermore, it delivers an ultra-clean break with adjustable pull weight

• Moreover, it uses aerospace-grade materials for durability and consistency

• As a result, it improves speed, longevity, and trigger control

• Ultimately, it dramatically upgrades factory 1911 fire-control systems

Compatibility

• 1911 pistols (Commander and Government models)

• Kimber

• Springfield Armory

• Colt

• STI / Staccato

• SV

• Para Ordnance

Notes

Although most installations are straightforward, some pistols may require fitting. Additionally, installation may require refitting or replacement of the thumb safety.
