Poor quality - Wilson Combat Shok-Buff Recoil Buffers

Guide rod is not smooth as you would expect, rough and bumpy. While I don't think it will cause any issue mechanically, you get a nice scraping sound of the spring on the guide rod. A standard Beretta plastic and metal guide rod both feel smooth and are virtually silent once lubed. Perhaps after a 10,000 rounds the roughness of the guide rod will smooth out from the scraping.

Guide rod diameter is also much thinner than a stock rod which visually looks odd and I if I used my pistol in adverse conditions I would be worried about dirt getting into the end.

All downsides to this product over a stock with the only plus a supposed possible spring life increase...
