Ignition Kit – Extreme Engineering Classic Commander 5 Piece

Extreme Engineering Classic Commander Ignition Kit

1911 / 2011 Fire-Control Upgrade – 5-Piece Set

Classic Commander Styling Combined with Competition-Grade Performance

The Extreme Engineering Classic Commander Ignition Kit upgrades your 1911 or 2011 with a refined fire-control system that seamlessly blends timeless Commander styling with elite match performance. Moreover, this ignition kit focuses on shooters who prioritize speed, consistency, and durability rather than cosmetic changes alone. As a result, it delivers a trigger pull that feels cleaner, resets faster, and remains consistent through extensive round counts.

Too often, shooters focus only on the trigger shoe. However, the true character of a trigger pull comes from the hammer, sear, disconnector, springs, and their precise geometry. Therefore, even the most expensive trigger shoe cannot compensate for poor internal fire-control parts. Because of this, the Classic Commander Kit replaces every critical wear component with aerospace-grade, competition-proven parts designed for long-term performance.

Why the Classic Commander Ignition Kit Excels Over Factory Parts

Advanced Materials and Lasting Geometry Stability

Most factory ignition systems rely on basic carbon steel with shallow induction heat treatment. Consequently, hardness wears quickly and limits safe tuning. Over time, shooters often notice gritty breaks, inconsistent pull weights, geometry degradation, and trigger weight drift.

In contrast, Extreme Engineering machines every component from a premium aerospace alloy originally developed for rocket booster engine applications. As a result, this advanced material provides exceptional strength, superior wear resistance, and long-term geometry stability. Furthermore, because all parts arrive fully precision-machined, gunsmiths avoid stoning hammer hooks or sear faces altogether.

Engineered for Consistency Under Heavy Use

Because these components retain their geometry even under aggressive tuning, the trigger pull stays stable and predictable. Therefore, shooters experience a cleaner break, a faster reset, and a significantly longer service life compared to factory or imported ignition sets.

Classic Commander Appearance with Ready-Out-of-the-Box Performance

Clean Pulls Supported by Fast Lock Time

Right out of the box, this ignition kit delivers a clean 4-pound trigger pull. Additionally, with only minor sear spring adjustment, shooters can easily achieve a consistent 3-pound competition pull. As a result, the trigger maintains stable geometry without pull-weight drift while also supporting ultra-fast lock time and precision shooting.

Moreover, Extreme Engineering manufactures every component in the USA and backs the kit with a lifetime warranty against breakage. Compared to imported ignition kits that rely on inconsistent steel and heat treatment, this system delivers dramatically higher durability and long-term consistency.

Exclusive Thunder Mountain Custom Advantage

Precision-Tuned Sear Spring Included

Only Thunder Mountain Custom includes a precision-tuned Standard Sear Spring with this ignition kit. Consequently, shooters gain a cleaner break, lighter pull potential, improved consistency, and enhanced long-term reliability. Standard ignition kits simply do not include this upgrade, which clearly separates this package from the competition.
