I think the P-10C is an outstanding design and a breakthrough for CZ. I did sand down the front and back straps slightly, but just enough to take the edges off. My first poly CZ, the P-07 DUTY also had very harsh checkering, and it "sanded" my fat gut while being carried concealed, so I thought I might go proactive to avoid a similar problem. After light sanding, no worries. My slide stop is still very stiff after 300 rounds, but I use the over the top method taught in our Academy, mostly, so not much of an issue. Everything else is loosening up. I do hope Cajun Gun Works comes out with a nice flat trigger with flush mounted trigger safety, but that's my personal take. The trigger is excellent the way it is. I have has one failure to feed, but that was one of my reloads, and most likely the cause of it.
