I have a pair of Type II Conversion Revolver I purchased from Cimmaron. The first one had rubbing issues with the cylinder and the area of the frame under it, can't remember what that area is called. Sent it back to them and they worked on it. When I got it back, the drop for the related cylinder was all but gone. They worked on this area on my second one before they shipped it to me and it had the same issue. They told me back then, which has been a while I could just carefully file them to create the drop and put cold blue on them. I am not a gunsmith by no means. I am thinking about taking them to my local gunsmith to see what he can do. Would this be an issue for you if they were your guns? Or should I just live with it?
