I wouldn't be too tempted to buy the CZ52...I've owned two of them, they tease you from afar but once you buy one its like a mirage and you realize the beautiful woman in the picture is an ugly old hag up close.
Gritty, gritty, gritty trigger.
Brittle firing pin almost certain to snap on you in a short amount of time
Big and heavy and not particularly well designed ergonomically
European style magazine release is a pain in the rear
Its just not that fun of a gun...even when it was cheap (I got my first one for $99.99). If you want to shoot the extremely affordable 7.62x25mm round then pick yourself up a Tokarev TT33, there's a gun that delivers all the goods.
