I own a CZ-52 because I find the roller locking action of historical interest and because I can't own an MG42
.I find it irritating to shoot because of lousy trigger,poor sights,poor grip,and a safety that insists on engaging during a string of fire.I do like the round,however,so I also bought a Norinco Type 54-1 Tokarev and I have had zero problems with it.It is reasonably accurate.Great flash/blast for range fun.I stick to S&B ammo.I tried some South African stuff and it was really bad.I wouldn't go near the corrosive combloc ammo for SMG's.
