One other thing, my friend:
The CZ mags are not top of the line by any means, but they are not junk, either.
Your CZ should function just fine with the factory mags and, if it is not, it is your ammo selection during the break-in period.
First of all, never ever ever use Wolf ammo in a semi-auto pistol. It's the same damn price as WWB for pete's sake.
One FTF in 300 is not bad during break-in, so I wouldn't trash your mags.
Put 1,000 rounds of Win-Clean or WWB FMJ through her, and then shuffle some HP's. I think you'll find your problem solved. If the mag really is too high on the rear of the follower, the spring is in backwards. Remove the base plate and invert the spring - it is canted and angled one way, and the highest end of the spring faces the front of the mag.
I'd double check all that, and then send CZ back the bad mag if it doesn't solve the problem. They'll give you a new one no questions asked. But I bet any mag problem is a reversed spring.
The Mec-Gar's are better, but like I said, you should have reliability with the factory mags.
