I LOVE my CZ-52....but it took some time and money to gain my affection. As issued, the edges of EVERYTHING are sharp. Painful sharp. The trigger was heavy, it misfired on all surplus (ran fine with my handloads, though) and I couldn't shoot it for crap.
But, there is something neat about the roller-locking and I decided to try to make it better. Wolff 18lb recoil and new hammer spring, extended slide release, hardened rollers, H&R firing pin, ghost-ring rear sight, new grips and a thorough de-fanging of the entire pistol with files and sandpaper resulted in a real gem!
The pistol now feels SO much better in the hand, doesn't rub or bite at all. Accurate and MUCH easier for me to hit with the ghost-ring vs. the tiny rear sight. Trigger much improved and the function nearly 100% with the affordable surplus ammo. Only the very occasional 'click' on a stubborn cartridge that needs a second hit to fire.
So, the finished pistol is a fine one. The stock pistol needs a LOT of work to be acceptable...at least by me. If you like to tinker, the CZ-52 is for you! If you want to shoot it out of the box and do nothing to it....like the others have said, you will probably be happier with something else.
