Star with calling CZ-USA tomorrow and ask for the gunsmith. I have noticed if I press the trigger way off to one side the trigger safety will get hung up. I have been told there is a quick fix for those who have skills/tools - I have neither. On the other hand, after about 300 rounds I didn't feel it again, and it never once happened during actual shooting, only dry fire. But if yours is wide enough that it hangs up on normal firing, I'd have CZ look at it and narrow it down a skosh or two.
