The CZ-52 was a huge disappointment to me. For ~$100, I got a large, uncomfortable, inconsistent, potentially unsafe, jammomatic range frustration (not toy, definitely) that was unpleasant to shoot for long strings because of the recoil impulse and sharp trigger edges. In comparison, for $135 I got a Makarov PM that was more reliable, accurate, useful, and able to be converted to .380ACP w/o the skills of a gunsmith. The only kind of 'tank' the CZ-52 resembles are the WW2 vintage ones that Saddam buried in the Iraqi sand. I wouldn't take a CZ-52 now if you paid me.
