Yeah. Don't let the low price entice you. These are crude guns with few redeeming features. (A few owners will defend them, but compared to a Bulgarian Makarov, they are bad news.)
The few I've seen, handled, and the one I've shot, had horrible double-action triggers.
For a few bucks more you can get a used .22 for plinking or a Kadet Kit for one of your CZs. If you want a small concealed carry gun, look at the Kel-Tec P3AT.
PA-63? I wouldn't go there.
