Good? They work every time.
Bad? they get dissed by ignorant people. That's actually good, in a way, because the price stays down.
Lots of commercial Maks out of Russia, Germans are getting hard to find and are the most colectable. Never that many Chinese imported. Bulgarian Maks are good, solid handguns.
They gun is designed around the 9x18, I can't see any advantage to having one in .380, except to be able to buy ammo at Wallyworld or the like. 9x18 isn't going to be everywhere, but by buying over the 'net ammunition is not a problem. I'm partial to S&B 9x18, not the cheapest, but boxer primed and reloadable. OTH, Wolf, Barnaul, and some of the Chinese still floating around are steel caseed, berdan primed ammo that you can blast away with and not worry about finding and retrieving your brass.
