Master the 1911 Trigger: Competition-Grade Chrome Silicon Mainsprings

Unlock the full potential of your 1911 or 2011 platform with our Competition-Grade Mainsprings. Engineered specifically for shooters who demand a refined, high-performance action, these springs provide the ultimate solution for customizing your ignition system. Whether you are looking to lighten your trigger pull for a crisp "glass rod" break or optimize your hammer fall for specific primers, these springs give you the control necessary to fine-tune your pistol’s performance with ease.

The Chrome Silicon Advantage

In the high-stakes world of competitive shooting, consistency is everything. That is why our mainsprings are manufactured from premium Chrome Silicon alloy. Unlike standard high-carbon steel, Chrome Silicon is legendary for its:

• Extended Service Life: It resists "taking a set" (losing length or power) even after thousands of rounds and years of being kept under tension.
• Fatigue Resistance: It maintains its exact weight and tension profile throughout the heat of a long match day, ensuring your trigger feels the same on the last stage as it did on the first.
• Superior Ignition Reliability: The uniform energy release provides consistent hammer strikes, which is critical for ignition reliability when using lightened competition setups.

Universal Compatibility

Designed for a seamless drop-in fit, these springs are compatible with the vast majority of full-size 1911 and high-capacity 2011 models. They are the preferred choice for USPSA, IDPA, and Steel Challenge shooters who need to calibrate their firearms for maximum speed and reliability.
