Recoil spring assemblies wear over time with normal use. If your pistol exhibits sluggish cycling, light primer strikes, or inconsistent performance, a worn spring may be the culprit. Replacing it with a factory assembly restores your pistol to like-new operation.
This is essential maintenance for any serious shooter who depends on their Glock for sport, training, or personal protection.
