A CZ will take +P ammo, but it'll batter the frame a little if you use the factory recoil spring. The factory spring is rated at 14 lbs. A 16 lb spring works well with normal pressure 9mm. An 18 lb spring generally works with normal pressure loads, but your may have malfuctions if you limp wrist. So, an 18 lb Wolff recoil spring should help quite a bit.
If you often practice with +P or +P+ loads, you could also install a Buffer Technologies recoil buffer made for the Hi-Power, but ONLY when you practice. The buffer is thick enough that it prevents the slide from locking back, but it'll save you excess wear on the handgun. I'd definitely take the buffer out when you leave the range.
