Fine-tune your 1911 Commander for softer shooting ammunition with the ISMI 14 lb. round wire recoil spring. This premium spring is a critical component for any shooter looking to optimize their pistol's cycling for target loads. Engineered for an incredible service life and unmatched performance, this is the go-to choice for serious shooters and gunsmiths.
The ISMI Advantage: A Lifetime of Performance
Not all springs are created equal. Unlike standard factory springs made from music wire that require frequent replacement, ISMI recoil springs are engineered for extreme longevity.
- Incredible 100,000-Round Service Life: ISMI springs are crafted from certified aerospace-spec chrome silicon alloy steel. This advanced material is heat-treated, shot-peened, and stress-relieved, allowing it to withstand hundreds of thousands of compression cycles without losing performance or taking a "set." This is a true "buy it for life" upgrade.
- Corrosion Resistant: Each spring is protected with a rust-preventative coating, ensuring reliability in all conditions.
- Made in the USA: Proudly manufactured in the United States by ISMI, a trusted name in high-performance firearm springs.
Application & Tuning Guide
A 14 lb. recoil spring is lighter than the standard factory weight (typically 18 lbs.) for a 1911 Commander. This makes it the ideal choice for:
- Target Loads: Perfect for tuning your pistol to reliably cycle standard velocity or reduced-power "softball" target ammunition.
- Shooters Using a Compensator: If you have a compensator installed, a lighter spring is often needed to ensure the slide cycles correctly.
- Reduced Recoil Feel: Pairing a lighter spring with lighter loads can lead to a smoother shooting experience with less felt recoil.

1911 Recoil Spring FAQ
When should I replace my recoil spring?
While standard music wire recoil springs found in many 1911s should be replaced every 2,000-3,000 rounds, ISMI's premium chrome silicon springs are in a different class entirely. They are engineered and rated for a service life of up to 100,000 rounds, making them one of the most durable and cost-effective upgrades you can make for your pistol's long-term reliability.
What's the difference between round wire and flat wire springs?
Round wire springs are the traditional, proven standard for the 1911 platform. Flat wire springs are a newer design that can offer a longer service life and a smoother compression feel. The choice often comes down to gunsmith or shooter preference. This spring is a conventional round wire design.
