Ignition Kit – Extreme Engineering Wide Spur(Bobbed) 5 Piece

Extreme Engineering Wide Spur (Bobbed) Ignition Kit

1911 / 2011 • 5-Piece Fire-Control System for Bullseye and Precision Shooters

Classic Wide Spur Style Combined with Modern Match Performance

First and foremost, the Extreme Engineering Wide Spur (Bobbed) 1911/2011 Ignition Kit blends timeless wide spur styling with modern, competition-grade fire-control engineering. Rather than forcing shooters to choose between classic aesthetics and performance, this kit delivers both. Additionally, precision machining, aerospace-grade materials, and optimized geometry work together to create fast lock time, consistent trigger feel, and long-term durability.

Moreover, unlike factory ignition systems that focus primarily on appearance, this kit prioritizes performance at every stage. As a result, your trigger pull stays clean, predictable, and stable through thousands of rounds. Therefore, it serves as an ideal upgrade for serious 1911 and 2011 shooters, especially Bullseye competitors who demand repeatable precision.

Why the Wide Spur (Bobbed) Ignition Kit Clearly Outperforms Factory Parts

Advanced Materials and Purpose-Built Heat Treatment

In many cases, factory ignition components rely on basic carbon steel with shallow surface heat treatment. Consequently, critical engagement surfaces wear quickly. Over time, trigger quality degrades, and shooters experience inconsistent pull weights, gritty breaks, slower lock time, and geometry loss.

By contrast, Extreme Engineering machines this ignition kit from a premium aerospace alloy originally developed for rocket booster engine applications. Because of this advanced material choice, the components deliver exceptional strength, superior wear resistance, and long-term geometry retention. Furthermore, after precise heat treatment to 50–54 Rockwell C, the hammer achieves an ideal balance of surface hardness and core toughness. As a result, the ignition system maintains consistent performance even under heavy competition use.

Wide Spur Design That Enhances Control and Confidence

Traditional Handling with Optimized Mass Distribution

On one hand, the wide spur profile increases surface contact and leverage. Therefore, shooters gain improved manual control and more confident hammer manipulation. In addition, this design enhances handling during rapid fire, gloved use, or high-pressure match conditions.

On the other hand, Extreme Engineering carefully optimizes mass distribution. Consequently, despite the classic spur shape, the hammer still delivers fast lock time and a highly responsive trigger feel. Ultimately, you benefit from traditional control without sacrificing modern competition performance.

Exclusive Thunder Mountain Custom Advantage

Precision-Tuned Standard Sear Spring Included

Notably, only Thunder Mountain Custom includes a custom Standard Sear Spring with this ignition kit. Because this spring receives precision tuning, it delivers a cleaner break, greater consistency, and improved reliability at lighter pull weights. Meanwhile, standard ignition kits rarely include this level of refinement. Therefore, this exclusive component further separates this kit from competing options.
