Both my wife and I have CZ-75Bs. We use 115 grain FMJ ammo for all our shooting. We have fired 5,000+ rounds through each of the guns with no jamming, FTE (failure to extract), or misfires. We have been super happy. We enjoy shooting at clay targets most of the time, although we also use splatter type paper targets. Since we live in the desert, we need only go a few miles to burn a box or 2 or 3 of ammo.
Hope you enjoy yours as we have enjoyed ours.
