I don't like the idea of carrying one for defense due to the lack of a decocker. If you're carrying a defensive sidearm there should be a round in the chamber. With the CZ, the only way to get the hammer back down after chambering a round is to pull the trigger and control the hammer (like one might for a revolver). I'm personally not very comfortable with that, even if I did it before leaving the house out in the yard with a safe backstop.
Arma, I am in the same opinion. I also have a CZ-82. Love the pistol but am not comfortable lowering a hammer on a live round. The CZ-83 is the same way.
