Wilson Combat Shok-buffs 1911 Government Pack Of 6

Prevents expensive frame damage when shooting high-pressure, major power factor loads. Replaceable, poly-fiber washer installs behind the recoil spring on any length guide rod. The shock absorbing action stops the slide from battering the frame during recoil by sandwiching a 1/10″ thick injection molded polymer buffer between the slide and frame contact areas. When you are shooting high performance loads in your 1911 style pistol, you want the extra protection that the original SHOK-BUFF provides.
