I saw a used CZ75B at a gun show this weekend. It appeared to be a Duo Tone with a satin nickel frame and a poly slide. The only problem is that the safety detent on the frame wasn't painted red. I doubt that it left the factory that way, and I've never seen one wear out, especially since the rest of the finish was 100%. I've never seen a satin nickel up close, nor a silver colored duracoat up close to say for sure, but to me it looks like a refinish. Any thoughts?
