a good rule of thumb is always to treat milsurp ammo as corrosive, do that and you will never go wrong. Nice CZ btw, I have a few of those guns and they are fun plus, you never know when you might neet a round that will penetrate kevlar easily. Crooks are wearing body armor more often these days and this is the only pistol round readily available that will consistently penetrate it.
Also, when I got mine I went ahead and ordered a replacement forged firing pin and a new slide release. The original pin can be brittle and I like having the option to release the slide with my thumb... just a few thoughts.
I love my CZ-52! It's a great pistol, mine hits waaaay low and left though. If I'm shooting at targets in the 50 yard range I have to aim several feet away from the target to hit it. I think it might need a new barrel. It's still a lot of fun to shoot though!
