Extreme Engineering Comet – 1911/2011 Ignition Kit (5-Piece)

Classic Commander Look with a Twist • Elite Fire-Control Performance – Ignition Kit

The Comet Ignition Kit provides a Classic Commander style hammer with the standard round hole with a tapering comet tail instead of the standard round hole.  This Ignition Kit provides an upgrade for your 1911 or 2011 competition pistol with that Extreme Engineering Classic Commander Look with a unique twist—a precision-engineered fire-control system built for shooters who demand speed, consistency, and long-term reliability.

Most shooters focus only on the trigger shoe. However, the true quality of your trigger pull is determined by the hammer, sear, disconnector, springs, and their geometry. These are the components that control crispness, smoothness, reset feel, and consistency. Even the most expensive trigger shoe cannot compensate for low-quality internal fire-control parts.

The Comet Kit replaces every critical wear component in your ignition system with aerospace-grade, competition-proven components designed to deliver a clean, stable trigger pull that stays consistent through thousands of rounds.

✅ Why the Comet Kit Outperforms Factory Fire-Control Parts

Most factory ignition components rely on simple induction heat treatment, resulting in shallow surface hardness. This limits durability and prevents safe tuning without cutting through the hardened layer. Over time, this leads to:

• Inconsistent trigger pull

• Gritty break

• Geometry wear

• Trigger weight drift

The Extreme Engineering Patriot Kit is manufactured from a premium aerospace alloy originally developed for rocket booster engine applications. This advanced material provides:

• Exceptional strength

• Superior wear resistance

• Long-term geometry stability

• Unlimited service life under competition use

All components arrive fully precision-machined—no stoning of hammer hooks or sear faces required. The result is a cleaner break, faster reset, and longer-lasting trigger pull than factory or imported ignition sets.

✅ Classic Commander Look with a Twist – Ready-Out-of-the-Box Performance

• Delivers a clean 4-lb trigger pull out of the box

• With minor sear spring adjustment, achieves a consistent 3-lb competition pull

• Maintains stable trigger geometry without pull-weight drift

• Designed for ultra-fast lock time and precision shooting

Extreme Engineering components are 100% made in the USA and backed by a lifetime warranty against breakage, offering unmatched long-term value. Compared to imported ignition kits made with inconsistent steel and heat treatment, this kit delivers dramatically higher durability and consistency.

✅ Exclusive Thunder Mountain Custom Advantage

Only Thunder Mountain Custom includes a custom Standard Sear Spring with this kit. This spring is precision-tuned to deliver:

• Cleaner break

• Lighter pull potential

• Improved consistency

• Better long-term reliability

Standard kits do not include this upgraded sear spring.
