The flat wire spring for 1911 handguns is an essential upgrade for both serious shooters and enthusiasts. Made from durable chrome silicon alloy, it offers superior spring longevity and load retention. With a service life up to ten times longer than conventional coil springs, it delivers improved cycling and works well with a wider range of loads. Designed for use with our flat wire guide rod system, it's recommended to replace the spring after 30,000-40,000 rounds. Note that it is only compatible with the flat wire guide rod and plug, not with standard recoil spring components.
