First things first - was the trigger catching on the bottom protion of the trigger guard in the return stroke? If so, contact CZ-USA, it's one of the very first that had this problem. If not, call 1-800-955-4486, ask for Mike Eagleshield, and talk to him - he'll take care of it for you. Please letus know what the issue is, when it's found. Thanks!
Edited for clarity - I meant to say, some of the very first P07s had an issue with the trigger catching the inside bottom of the trigger guard, and they already fixed that issue on all subsequent guns.
