I recently picked up a wilson combat shok buff kit for my S&W 1911. I was just wondering if anyone out there has used these and if they really make a difference. I don't expect anything dramatic, i just want to minimize wear on my Scandium alloy frame and internals. I bought the 2G kit which includes a much longer spring as well as 2 buffer pads. If you have used these with success, lemme' know about it. Thanks - Texmex
