The Wilson Combat SHOK-BUFF for the Beretta 92 prevents the slide from battering the frame during recoil by sandwiching a 1/10" thick injection molded polymer buffer between the slide and frame contact surfaces. When shooting high performance loads in your Beretta 92 style pistol, you will want the extra protection that the SHOK-BUFF provides. By slowing slide impact, the Beretta 92 SHOK-BUFF also tames the felt recoil impulse and reduces muzzle flip. The SHOK-BUFF is ideal for all uses but especially high round count practice sessions or when firing +P ammunition. Mfg: Wilson Combat
