Description

Discover the “sweet spot” for your full-size 1911 with the ISMI 15 lb. flat wire recoil spring. This is the ideal all-around performance spring for shooters who want to reduce felt recoil and achieve a smoother cycle with standard factory ammunition. The advanced flat wire design provides a premium feel and an exceptionally long service life, making it one of the most popular upgrades for any Government model pistol.

The ISMI Advantage: Flat Wire Technology

ISMI’s flat wire recoil springs offer a distinct performance advantage over traditional round wire springs, making them a favorite of custom builders and serious shooters.

  • Smoother Recoil Impulse: The flat wire design compresses more linearly than round wire, resulting in a smoother, less “snappy” felt recoil that helps keep your sights on target during rapid fire.
  • Exceptional Durability: Crafted from certified aerospace-spec chrome silicon alloy steel, these flat wire springs are rated for an incredible service life, resisting wear and taking a “set” far longer than any music wire spring.
  • Made in the USA: Proudly manufactured in the United States by ISMI, the top choice for high-performance firearm springs in nearly every shooting discipline.

Application & Tuning Guide

A 15 lb. recoil spring is a popular tuning weight, sitting just slightly below the factory standard (16 lbs.) for a 5″ Government model 1911. This makes it an excellent choice for:

  • Standard Factory Ammunition: Perfectly tuned to provide flawless cycling with common 230gr FMJ “hardball” ammunition, while offering a noticeably softer recoil impulse than a factory spring.
  • Improving Split Times: For shooters looking to improve their speed, the slightly lighter weight allows for a faster slide cycle, helping to reduce the time between shots.
  • General Range & Training Use: The ideal “do-it-all” tuning spring that enhances the shooting experience without sacrificing reliability with standard pressure loads.

1911 Recoil Spring FAQ

What’s the difference between a flat wire and a round wire spring?

Flat wire springs, like this one, compress more linearly, which can result in a smoother felt recoil impulse. They also tend to have a longer service life. Round wire springs are the traditional standard and offer a more conventional compression feel. The choice often comes down to the shooter’s preference for recoil feel.
