Ah...the CZ-52.
This is a great gun to shoot (if you can get past the bad ergonomics and the recoil.)
These things are real tack drivers, I've hit steel targets at 100 yards with them.
Since the round has a high velocity and light bullet, the gun tends to shoot very flatly, just point and click.
If you do pick one up, though, I would recommend that you mosey on over to
www.makarov.com and pick up one of the Harrington firing pins, along with an 18.5 lb Wolff recoil spring.
The recoil spring is a must, especially if you shoot hot ammo through it. The ones that come with the pistol are kinda cheesy, and will allow the roller mechanism to beat itself against the inside of the slide, which will eventually knock the roller loose.
These are excellent pistols, they just need a little bit of TLC, and they won't disappoint you.
