Glock's

The recoil buffer for the Glock pistol eliminates the metal slide from impacting the polymer frame. This repeated impact batters the frame where the two parts come into contact. When the buffer is inserted between the recoil spring and the slide, it eliminates the battering. Each time the action is worked or the weapon is fired the buffer comes into contact with the frame, not the metal slide. 

Installation of the Glock Recoil Buffer will result in reduced felt recoil, enhanced muzzle control and a longer service life. 

The Glock Recoil Buffer will fit models 17, 17L, 18, 19, 20, 21, 22, 23, 24, 24C, 31, 32, 34 and 35.
