ISMI – 11 Pound 1911 Government Recoil Spring

ISMI 11 lb 1911 Government Recoil Spring

Optimized Recoil Control for Light Target and Competition Loads

The ISMI 11 lb 1911 Government Recoil Spring delivers a precise solution for shooters running light target ammunition, competition loads, or reduced‑power setups. When standard recoil springs prove too stiff, this lighter spring allows the slide to cycle smoothly and consistently. As a result, your pistol functions reliably even with softer‑shooting ammunition.

Because light loads generate less recoil energy, a standard recoil spring may fail to drive the slide fully rearward. Consequently, feeding, ejection, and slide travel can become inconsistent. This 11 lb recoil spring addresses that issue by promoting full slide movement, clean feeding, and consistent ejection. Therefore, your 1911 continues to run smoothly shot after shot.

Built for Consistency and Long Service Life

This recoil spring is manufactured from premium chrome silicon wire. Compared to conventional spring materials, chrome silicon offers superior resistance to heat, fatigue, and deformation. As a result, the spring maintains its intended rate longer and delivers consistent performance over extended round counts.

In addition, ISMI’s tight manufacturing tolerances ensure smooth compression and predictable recoil behavior, which is especially important for competition and precision shooting.

Why Choose an ISMI 11 lb Recoil Spring?

An 11 lb recoil spring is an excellent choice when your goal is reliable performance with light ammunition. Specifically, it provides:

• Smooth cycling with light or reduced‑power loads

• Reliable feeding and consistent ejection

• Faster follow‑up shots due to reduced recoil impulse

• Less effort required when racking the slide

• Predictable operation for target and competition use

Because the spring rate is lighter, the slide moves more freely. As a result, short‑stroking is reduced and overall control improves. At the same time, felt recoil softens, which supports better accuracy and faster target reacquisition.
