My brother just bought a S&W mod.457 45 auto and I was wondering if any of you out there have had any experience with it. It looks easy enough to carry concealed, but I haven't shot it yet and my wife has a hard time racking the slide, so I don't think it would be a good ladie's model. My brother paid around $400.00 for it used from the original buyer.Is this a good price for it?
