Ultimate Arms Gear Shock Recoil Buffer For Glock Pistols(Not for Gen.4). Polyurethane buffer cushions the impact and absorbs the shock of the slide against the polymer frame during recoil, resulting in less wear to the gun, less fatigue on the hand and arm, and less muzzle rise. Reduces felt recoil so you can get back on target quickly for faster, more accurate follow-up shots. Each buffer is precision CNC cut from a sheet of ultra-tough, tear-resistant polyurethane. Drop-in installation without any permanent alteration to the firearm-slides over the recoil spring guide between guide and spring. Will fit models 17, 17L, 18, 19, 20, 21, 22, 23, 24, 24C, 31, 32, and 37. It will not fit Generation 4 Glocks. Rated to last up to 1000 rounds of repeated firings and is easily replaceable
