ISMI – 16 Pound 1911 Government Recoil Spring

ISMI 16 lb 1911 Government Recoil Spring

Keep Your Government-Length 1911 Cycling Smoothly and Reliably

The ISMI 16 lb 1911 Government Recoil Spring ensures that your Government-length 1911 operates smoothly and consistently, whether you shoot standard or full-power ammunition. From the first round to the last, this spring maintains proper slide speed, promotes clean feeding, and delivers reliable lockup. Consequently, your pistol functions predictably every time, whether you carry it for duty, use it for competition, or train at the range.

Moreover, ISMI manufactures each spring in the USA using advanced CAD design and aerospace-grade standards. Because of this precision, every spring delivers consistent performance, superior strength, and long-lasting reliability. Therefore, you can trust your 1911 to cycle flawlessly round after round.

Strength and Reliability You Can Count On

ISMI produces this recoil spring from premium chrome silicon wire, which resists heat, fatigue, and deformation. As a result, the spring maintains its rate over thousands of rounds. Consequently, slide timing remains consistent, and your pistol cycles smoothly every time.

In addition, ISMI applies multiple finishing processes to maximize durability. Each spring undergoes heat treatment to increase strength, shot peening to reduce surface stress, and full stress relief to prevent permanent set. Together, these steps maintain consistent tension while reducing wear on the slide and frame. Therefore, your 1911 continues to function reliably over extended use.

Why Upgrade to an ISMI 16 lb Spring?

Factory recoil springs gradually lose tension, which can cause inconsistent slide speed, feeding problems, and excessive frame wear. By upgrading to an ISMI 16 lb spring, you restore proper slide control and improve your pistol’s overall performance.

Furthermore, the 16 lb spring handles both standard and full-power ammunition safely. Because it effectively controls slide movement, it protects internal components while maintaining smooth, predictable cycling. As a result, you achieve consistent function and reduce the risk of component wear over time.
