This is a genuine Glock factory recoil spring assembly for the Glock 20, 20SF and 21. The recoil spring controls slide travel and returns the slide to battery, and it wears with use, so replacing it on schedule keeps the pistol cycling reliably. A factory assembly drops in as a direct replacement for the original.
