Hi All,
I foolishly went to a local gun show with cash money in my pocket, figgering I would pick up some Tok 7.62x25 for my CZ52, and ended up bringing home a CZ 82 as well as the Tok ammo.

I am working my way up the CZ food chain, a 75B is really what I am looking for, but a CZ in the hand is worth two on Gunbroker, or something...
Anyway...
I have the 82 in the Mak round, 9x18. That part I understand.
But I see references to the 83 in 32 AND 380 (or as more properly noted, 7.62 and 9mm kurtz.)
I had thought that the 82 indicated the Mak cartridge, and the 83 indicated th 380 cartridge, but this apparently is not correct, the 83 comes in two flavors, 32 and 380?
My 82 has the polygonal rifling which threw me (and still does) for it looks like a smoothbore. If there is rifling in there, it must have been put in by laser etching BUT this appears to be the way the barrel is. The gun has holster wear but the rest looks very clean. Pix coming.
Can someone pls explain the 82/83 differences, and the nature of the polygonal barrel?
Oh, and how does one determine year of mfg.?
Thx!
