I was just at a gun shop and saw a new 586 3in chambered for 38/357and 9mm with moon clips. The cylinder was milled? out to accommodate 9mm para. It also had a ported barrel.He said it was from S&W that way. I can't find it on the S&W web site. Anybody seen this? It was a beautiful revolver. Could you take a 586 or 686 to a gunsmith and get this done to it?
