I have a CZ 40P and wouldn't trade for it. I thonk that's the P-01 frame and a different slide. That slide is now used on their 40B frame that isn't as ergo.
It doesn't like blazer aluminum cases or real, real flat nose bullets.

I've never seen a CZ of any kind malfunction on specific ammo - you might want to send that one back to KS and let them take a look.
