Understand that this pistol shoots 9mm
Makarov ammo, not the more common 9mm Luger round. Shooting Luger ammo in the -82 cold be disasterous. Mak rounds are slightly shorter but larger in diameter.
The most obvious weak point, to me at least, is the grips. Because they use a single screw attachment and no other pin to secure/position them, the grips tend to work loose during firing. The grips also had cracked support strips on both -82s I bought. Nothing that interfered with operation, but I chose to order wood grips from Marschals in Hungary.
Some have put a small "o-ring" under the screws to help keep them from loosening, but I've used thin (photo album) double-sided tape to prevent the grips from shifting.
Some have problems with the mag release being difficult. It disassembles easily and can be cleaned/polished up to help.
The CZ-82 uses the same part as the -83, the exception being the barrel and the slide lock lever. The -83 has a square trigger guard (which I don't like) but I believe it will fit the -82.
Expect the pistol to be gummed up, many are sprayed with a preservative. It takes a thorough cleaning to get it all out. A can of "non-chlorine" brake cleaner will do the job. Break down the mag(s) also. They can be pretty dirty inside. The bore is larger than a 9mm Luger (.365 to be exact) and you'll probably need a larger brush to clean it. I use a .40 brush with no problems.
Don't be alarmed if it looks like the rifling is all shot out. It will look like a smoothbore. That's normal.
There's no telling what wear and tear the recoil spring might have or # of rounds fired, so I'd suggest ordering a replacement recoil spring or calibration pack from Wolffs. It comes with a new hammer spring also, which is easily replaced.
I refinished mine with DuraCoat (see avatar), but it's by no means a requirement. Functionally, I haven't any issues with mine and it's gobbled up all factory ammo and reloads I run thru it. Great gun, my favorite shooter.
