I know I'm new to this forum and posted a question about nitrated paper, but I would like to pass on what I know about this particular subject. Unless looking for historical accuracy, I would avoid brass frame revolvers. Perhaps, in re-enacting only firing blanks, they're OK and, on the plus side, the brass won't corrode as quickly on the frame if forgotten to get cleaned after an event. If you plan to use for 'live firing' (shooting bullets) some of these brass frame revolvers will actually beat themselves up from the recoil/pressure from shootings balls/bullets. Some manufacturers use softer brass than others which only accelerates the problem. The problem is the recoil slams the cylinder back against the frame and, over time, will cause enough 'slop' in the fit of the cylinder to frame that the gap increases between the cylinder and barrel to make jump fires a real problem. Before all you owners of brass frame revolvers desend upon me, I own a brass-frame Pietta '51 Navy that, with some machinework, I converted to a Dance Brothers revolver, which I use ONLY with blanks at events. I 'live fire' my steel-frame '60 Colt .44s and '59 Remingtons only, which I also use at events with blanks. I also try to clean them after every battle, if possible, or as soon as I get home. Buy what you want, or can afford, but remember if you want to 'live fire' a brass frame, it can ruin your pistol in the long run.
