Glock Factory Recoil Spring Assembly Gen4 .40 S W .357 SIG .45 GAP

The Glock OEM recoil spring assembly for Gen4 models 22, 31, 35 and 37 delivers factory reliability and consistent performance when you're maintaining .40 S&W, .357 SIG and .45 GAP service pistols, and it's the same quality-built component Glock installs in their ultra-reliable pistols. If you run duty, competition, or range sessions, swapping in an OEM recoil spring assembly keeps slide timing, felt recoil and lockup within factory tolerances so your pistol cycles like it was built to; operators and armorers will appreciate the tight tolerances and durable materials that hold up to high round counts and varied ammunition. This part is a direct-fit OEM item for Gen4 frames, so installation is straightforward and it restores original factory dimensions that aftermarket springs can alter. For armorers, hunters who carry a backup, or recreational shooters who demand predictable function, using a Glock OEM part reduces troubleshooting time and extends service life of slide and barrel components.
