I put the Hogue wood grips on mine, and it helped a lot with the sharp edges on the front and backstraps. I ran surplus ball ammo in mine for a while, then bought several hundred pieces of Starline 7.62x25 brass, and have been pushing Sierra 86gr RNSP pills over 1600 fps on top of a goodly amount of Accurate Arms No.5. But if you find one of these pistols, do yourself a favor and look for a "Z" on the triggerguard. If it's not there, clear the chamber and barrel, and put a No.2 pencil eraser first into the barrel until it seats against the breech. Cock the hammer, and, holding the muzzle upright, try the safety's decocker function (sweeping it up). If the pencil jumps out of the bore when the hammer falls during decocking, you have reason to pass up on the gun, or send it back to the importer, Century Arms International had a fix for them a while ago...
Otherwise, I love my CZ-52, it's stout, accurate (but I handload...), and can really knock over a steel plate at 50 yards like nobody's business!
