Mine (urban gray) is a P01. I'd had it maybe 6 months when I noticed the front sight glow was gone. It worked Sunday, Tuesday or Wednesday I noticed it was "out". I e-mailed CZ USA, got a reply later that day, got the return authorization stuff in an e-mail the next day and shipped the stripped slide (took it off the frame and removed the barrel and recoil spring/guide) to them. FEDEX lost/messed up that label and that took it about 3 extra days to get back to CZ USA.
CZ USA fixed it and shipped it back to me about 3 days after that. No issues with it since.
No idea about the finish. I'm one of those guys that dings it if I carry/use it, so mine are going to get marks in the finish anyway.
