Just bought a used CZ 82 at my local gun store. I guess used by Checz police. Nice gun. It uses the 9x18 ammo. What is that equivelant to? 380? I find that it is harder to get and more expensive. I have a regular 9mm Ruger 89 but this was a small carry gun. Seems to be well built and smooth. Figured I couldnt go wrong for $219. with holster, extra clip and cleaning rod. But worried about the ammo. How does it compare to a 38.?
