I had two separate issues with my sample size of one. I bought one of the early serial number P10c's and experience the "striker rotation" that some people were having. The gun would be prevented from going into battery because the striker would rotate in the channel. Called CZ shipped the gun to them and they fixed it. After I got it back I put probably another 500 rounds through the gun and the striker broke just like the pictures from CGW. Same thing called CZ shipped it and it came back fixed.
From reports I've seen the new ones are G2G but the low serials like the one I had are where the problems seem to occur. I chalk it up to teething issues with a brand new gun. CZ did the same thing with the P07 Duty/ P07 (front cocking serrations model) where the "gen 1" came out had some issues they fixed it and rolled out a pseudo "gen 2".
