Manufacturer: Wilson Combat 2
The Wilson Shok-Buff prevents the slide from battering the frame during recoil by sandwiching a 1/10" thick poly fiber 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. The object of the frame to slide buffer is to protect the pistol from wear; if the buffer is not soft enough to take the damage instead of the pistol, what have you accomplished? We feel the original Shok-Buff is the optimum balance between shock absorption and longevity. Easily replaceable after absorbing up to 1,000 rounds of repeated firings, the Shok Buff slides over the recoil spring guide between guide and spring.
Due to space constraints, Wilson does not recommend Shok Buff buffers in Colt Officers, Springfield Compact or Para-Ordnance P12 pistols.
