The 7.62x25 is a fire-breathing monster with severe over penetration potential. Couple this with a single action only pistol with a goofy and often broken safety that was tacked on and you've got a very poor SD gun. Don't forget that commercial ammo for that is pricey.
And I would add that the surplus ammo is corrosive, and they're not horrible to field strip, but I wouldn't call it easy either.
The SA trigger pull is awful. The ammo is anemic and dreadfully expensive for what it is. These guns are only good to "complete the look" if you're a Russian collector.
This is a great gun for beginners or as a SD gun / BUG.
The CZ-82 is cheaper to shoot is you go with Silver Bear ammo. It's really a joy to shoot because of the decent trigger and accuracy. Finish on most is crap, but hey, it's under $250 for a CZ.
The CZ doesn't have a decocker so you have to carefully lower the hammer after loading.
After shooting my CZ, Doggymama's dad had me order him one from AIM. His was nicer than mine! I do like the "automatic safety" if you will, that engages a block such that the trigger has to be pulled fully in order for the hammer to come in contact with the firing pin. Just a little extra bonus if it's dropped.
