Very nice guns, well made, nice fit and finish. Dan Wesson guns are very good quality. I don't have one but I have friends who do. It is a true "Officers ACP" size gun with a 3.5" barrel same as the original Colt Officers ACP (Commanders have a 4.25" barrel, a Commander slide on an Officers frame is a CCO), and it is light weight thanks to the aluminum frame. I imagine they're using something like Wilson's flat wire recoil spring set up, to get that kind of life out of it, often the normal round wire recoil springs are only good for a couple of thousand rounds in the shorter guns. I haven't heard any complaints about them and the reliability issues of short 1911s are pretty much a thing of the past, I've never had any trouble with mine.
