A quick question for those with revolver experience. I know the brass frame revolvers stretch after a lot of shooting but I'm wondering if its because of recoil or the pressure applied when loading? I have a brass frame colt and was aware of the problems with them but I'm a casual shooter with limited opportunities to get out to the range. Even with the brass frame it will be a few years before I have a stretching problem. Any way, will loading the cylinder off of the frame prolong the life of the gun? Your humble and considered opinions welcome.
