Well, I have only fired 80 rounds through it, but my new 75compact 9mm was reliable with the the twenty Hydra-Shoks that went through it, and accurate, puching a 10 round, 1.5" group at 7 yards in a two hand hold, dead centered on the bull. It doesn't like Win-clean much, but loves SB range ammo, as well as the Geco stuff. Working at a range gives me access to much testing ammo, and the work will go on today. Only problem I have is it won't drop mags free when they are empty, with all three mags I've tried. I am thinking of taking it to our gunsmith, but hate spending money on something I ought to be able to fix!
Regardless, I am very happy with this gun, and will buy more CZ's in the future.
