I have a CZ-83 in 9x18 mak.
The CZ-83 was available in .32, .380 and 9x18. The .380 is usually always available, whereas the other two come and go depending on the market.
The CZ-82 is basically the same gun as the CZ-83 in 9x18, except it has a "3" instead of a "2" and the trigger guard is round on the 82. I kinda like the round trigger guard personally, though my 83 has the hooked one.
The .32 and .380 barrels are rifled, the CZ-82 and 83-9x18 are polygonal rifled.
The mags are double stack, hi-cap. Because the 9x18 is a hair wider than the .380, you end up loosing one round in that caliber. It's 12 rounds in .380 and 11.75 rounds
(i.e. you get 11 and almost number 12 in there) in 9x18.
The gun is straight blowback, and the larger grip caused by the bigger mag make it easier to hold onto than the Makarov pistol. DA, cocked and locked, ambi controls, etc, typical CZ quality and design. Slightly bigger than the Makarov, but not Beretta 92 size. It's a fairly good size gun though, and not really a pocket gun unless you have big pockets.
Mine shoots heat. It's a very accurate gun, the trigger is very nice, the sights are nice and it works well with S&B and Hornady JHPs. It didn't like Wolf out of the box. A couple of the first rounds failed to close the action with Wolf. The Wolf didn't group as well, and overall my gun just didn't like Wolf. I tried out S&B (which is Czech as well, so they spoke the same language) and the gun sang. The Hornady JHP's were the most accurate of the three loads, and hit at the same POI as the S&B making practice cheap. There were no failures with any of the loads other than the couple early on with Wolf. It seemed like the extractor just wasn't snapping on over the rim on the Wolf. Eh, I just shoot the S&B now and use the Wolf in the Makarov.
There's stronger calibers to carry in a gun it's size, and there's smaller guns in the same class of caliber, but the CZ-83 likes to be shot. Frankly, it's a fun gun to shoot. I'd recomend one to anyone wanting something more refined than a Makarov, and really if you were in the market for a .380 you can't go wrong with one of these in that caliber either. I'd rather have the CZ-83 than a Beretta 84 personally. It just has more character to me.
Makarov.com are good folks from all I've heard. If you want one, the deal they have sounds like the ticket.
