Finally...after several phone calls and much internet digging, I got my P10c hitting where I want it to.
I purchased a new P10c and the factory sights were way off...hit 3" high at 7yds...repeated phone calls to the Mothership did not give any hope for an easy solution, until I contacted the guys in the Custom Shop...they sold me a new front sight ( fiber optic) which I prefer anyway, and it was the next size taller to help with the elevation issue.
Next range session was much better, with the new sight hitting POA-POI
I'm happy I was able to resolve the issue, but a bit disappointed CZ did not comp me the sight...I mean it left the factory with an unacceptable issue that they should have covered...but the new sight was not expensive and it fixed the problem, so we are good to go.
