Ignition Kit – Extreme Engineering – Tactical II – 5 Piece

Extreme Engineering Tactical II Ignition Kit (5‑Piece)

Skeletonized Commander Hammer for 1911 and 2011 Pistols

Upgrade your 1911 or 2011 carry or tactical pistol with the Extreme Engineering Tactical II Ignition Kit. This five‑piece system delivers proven Extreme Engineering reliability at an accessible price point. At the same time, it improves lock time, sharpens trigger response, and maintains long‑term consistency. Because the kit uses a skeletonized Commander‑style hammer that weighs less than the standard Tactical hammer, it enhances performance without sacrificing control or durability.

Why Internal Fire‑Control Parts Matter Most

Many shooters focus on the trigger shoe alone; however, the hammer, sear, disconnector, and springs actually define trigger quality. These components control crispness, smoothness, reset feel, and long‑term consistency. Therefore, even a premium trigger shoe cannot overcome poorly designed or low‑quality internal parts.

For that reason, the Tactical II Kit replaces every critical wear component in the ignition system. As a result, your pistol delivers a clean, stable trigger pull that remains consistent through thousands of rounds.

Why the Tactical II Kit Outperforms Factory Fire‑Control Parts

Most factory ignition components rely on basic induction heat treatment. Consequently, they develop only shallow surface hardness that wears quickly. Once shooters tune these parts, they often remove the hardened layer entirely. Over time, this causes gritty breaks, geometry wear, inconsistent pull weight, and trigger drift.

In contrast, Extreme Engineering manufactures the Tactical II Kit from a premium aerospace‑grade alloy originally developed for rocket booster engine applications. Because this material offers exceptional strength and wear resistance, it preserves precise geometry under hard use. Furthermore, Extreme Engineering precision‑machines every component, so you do not need to stone hammer hooks or sear faces. As a result, the system delivers a cleaner break, faster reset, and longer service life than factory or imported ignition sets.

Ready‑Out‑of‑the‑Box Performance

Straight out of the box, the Tactical II Ignition Kit delivers a clean and predictable four‑pound trigger pull. Additionally, with minor sear spring adjustment, you can tune the system to a consistent three‑pound competition pull. Because the components retain their geometry, the trigger pull stays stable without weight drift. At the same time, the lightweight skeletonized Commander hammer produces fast lock time and a more responsive shooting cycle.

Extreme Engineering manufactures all components in the USA and backs them with a lifetime warranty against breakage. Therefore, compared to imported kits made from inconsistent steel and heat treatment, this system delivers significantly greater durability and long‑term value.

The Thunder Mountain Custom Advantage

Only Thunder Mountain Custom includes a custom Standard Sear Spring with this kit. Because this spring is precision‑tuned specifically for the Tactical II system, it produces a cleaner break, supports lighter pull weights, and improves long‑term consistency. Standard ignition kits do not include this upgraded component.

What’s Included in the Tactical II Ignition Kit

Tactical II Skeletonized Commander Hammer

This chamfered, low‑mass hammer weighs only 0.7 oz. As a result, it delivers one of the fastest lock times available while improving trigger response and shot‑to‑shot split times. Extreme Engineering heat treats the hammer to 50–54 Rockwell C and designs it to fit Colt, Kimber, Springfield, STI, SV, Para, and Springfield Prodigy pistols.

Tactical Precision Sear

Extreme Engineering manufactures this sear from the same aerospace‑grade alloy used in its premium hammers. It heat treats the sear to 44–46 Rockwell C to ensure geometry stability and prevent follow‑down. Consequently, the sear excels in both defensive and competition‑oriented pistols and has proven itself in match guns nationwide.

National Match Disconnector

This lightweight disconnector improves reset consistency and enhances reliability during high‑speed cycling. As a result, it performs smoothly during rapid double‑taps and extended firing strings.

Thunder Mountain Custom Standard Sear Spring

This exclusive spring delivers a crisp break, stable light pull weights, and a smooth trigger feel. Because it outperforms standard factory sear springs, it significantly improves overall trigger consistency.

Wolff Precision Mainspring

Choose a 15 lb, 17 lb, or 19 lb mainspring to balance trigger feel and ignition reliability. Wolff Precision GunSprings provide consistent pressure and long service life, making them the industry standard.

Compatibility

The Tactical II Ignition Kit fits 1911 and 2011 platforms from Springfield, Colt, Kimber, STI, SV, Para, and Springfield Prodigy, as well as custom 1911 and 2011 builds.

Important Fitment Notes

Some pistols require thumb safety fitting. Additionally, certain setups require a new thumb safety for proper sear engagement. Therefore, a qualified pistol smith should perform minor fitting to achieve optimal performance.

Built for the Serious 1911 and 2011 Owner

If you build or upgrade a serious carry or match‑ready pistol, the Extreme Engineering Tactical II Ignition Kit delivers faster lock time, a cleaner break, lighter and more stable pull weights, and superior wear resistance. Because it combines aerospace‑grade materials, precision machining, a lifetime warranty, and an exclusive Thunder Mountain Custom sear spring, this kit delivers elite‑level fire‑control performance that stands up to hard use.
