Just put 50 rounds through my new(1954) CZ52. What a sweet shooting gun! The range manager asked to fire a few rounds and was impressed. Accuracy is spot on and he loved the trigger.
Just don’t trust the decocking function, and get a couple of spare firing pins. I don’t leave a round chambered at all, safety or not. It is so easy to work the slide that I just leave it empty. And get some Serbian “Golden Bear” hollow points. They expanded in my basic “shoot into sand” tests to the same .50 cal diameter as my 9mm hps.
PS: Look for good original milsurp mags, with the slotted sides. They function much better than the aftermarket ones. Some of the aftermarket mags cause rounds to bind up, especially the hollowpoints, due to their length and the geometry of the bullet ogive. Make sure of your mags and ammo, and you are good to go. Also, if you like the pistol, get some nice tropical wood grips from Hogue. The commie plastic grips are ugly, and the striped tulipwood or other wood grips make the pistol pretty, and feel better. They are worth the $50 or so bucks, IMHO, strictly from a cosmetic POV. The metal grip retaining clips can also break, you might pick up a spare.
