It is an MK9, but the frame is the matte finish, and the slide is the blackened stainless. I looked on the web site for the same pistol, but wasn't able to find it. What gives about the two tone?
I don't think I've ever seen a Kahr with stainless frame and blackened slide... I'd think that might be a custom jobbie... But the E9s had the black frame and SS slide... I think it also had a staked on (or somehow not dovetailed) front sight and were supposedly a bit rougher.
