I wanted one ever since I saw it in the reference book W.H.B. Smith's "Small Arms of the World" in the 1960s. I thought it was exotic. Still do. Maybe I had low expectations as to practicality, so I was overall pleased with it once I shot it. It is not an ideal weapon, but I bought it as a historic collectible back when they were 129.00 with holster, 2 mags, cleaning rod, and lanyard (ca 2004).
I use the decocker to release the hammer, with the thumb of the offhand blocking the hammer fall, and never lower the hammer on a loaded chamber anyway. And JIC I bought two spare firing pins but normal use (live fire, no dry fire) does not seem to be a problem.
I shoot it occassionally in modern military matches and accuracy depends a lot on the ammo. Some lots of military surplus are all over the paper, others shoot better. Ever so often, I shoot S&G 7.62x25 boxer-primer factory ammo from the bench to collect empties to reload for my old broomhandle C96. In fact I have carried the CZ 52 as a woods walking sidearm on the mountain.
Like Ash above I got a batch of good looking 1986 surplus ammo that at least every magazine there is one round at least that requires a second strike. It is great at the range for curing a case of the flinchies: I learn to hold through and not anticipate recoil, to avoid the embarassment of dipping or heeling when the hammer goes click instead of the round going bang. Commercial ammo from the same manufacturer with boxer primers runs perfect in the CZ52, so I suspect a batch of ammo intended for slam-fire open-bolt SMG use (packed 70 rounds per box, berdan primers, PPU headstamp). I got the same effect with a different pistol by reloading with small rifle primers instead of small pistol primers.
