I've got a nice looking combat master in layaway at my LGS. Its to be an early Seattle, WA gun, serial #187**. It looks stainless but I'm not entirely sure, could be chrome or nickel. The rear sight is fixed and it has the flat pachymayer MSH. What I want to know is what Mark is that pistol? Is that chrome, nickel or stainless? To me it looks stainless because it didn't have that super shiny, chrome bumper look and it didn't have that warm, tan hue that nickel seems to have. From what I've read if it is stainless then it is a Mk V, but if it's nickel then it is a Mk II. Also it comes with two magazines that I believe are original, they are marked Detonics 45 ACP and they fit flush.
