I had a Pachmayr Combat Special years ago. I would like to know more about guns build by Wetstein that are marked AUTO SHOP. The one I am looking at is build on a 1980 full size series 70 .45 Colt. But it seems a bit different than the one that was for sale on this forum. Main differences are : real beavertail , single finger grove , one piece mag well, regular thumb safety, black carbon fiber trigger, frame seems to have undercut bellow trigger guard Gun is 99% +.
