CZ-82 not Polygonal rifling?

I just bought my first gun (CZ-82) a month ago and love it. I have some questions and concerns. First, I paid $185 for it. It has some nicks and scratches, but in very sound shape. My question is the rifling. I am reading I should not be able to see the rifling since its "hills and valleys" but I can clearly see the lands and grooves.

So my question is: Is it polygonal and just not worn in yet? Did I perhaps get a gun that had an "aftermarket" or replaced barrel? The barrel number and the number on the slide are the same. Did I get ripped off by not getting it polygonal? Now I know im new and I wont notice a difference but what about resale? Basically I just want to know what it is that I have here. Thanks! picture below!

That is not a factory 82 barrel or at least one I have ever heard of. I think the supply of 82s dried up as I had not seen them for the super cheap prices they had been going for so this my be why they have come back on the market in the 170-180 range. You just bought the best value in the gun market so I would not worry aout it to much as long as it shoots. Can I ask who imported the weapon?

A lot of them were redone or built from parts by CAI, as far as I know they were the only people putting after market barrels on them.

It was a gun dealer here in Indiana, I think it was Leathers Unlimited or something, but he had it sitting around from a trade so I didn't need to pay a shipping/importing fee.

Is it .380 or 9x18? I've never seen a 9x18 cz82 with traditional rifling, and I'm pretty sure that's not factory. But if I'm not mistaken the .380 cz83s are traditionally rifled. Maybe somebody modified a makarov barrel to fit. I dunno.

You can tell by the trigger guard that its an 82. It prob has an 83 barrel in 9x18 as they do make an 83 in that cal

For what ever reason, Century Arms International sold a huge number of CZ-82's with AFTER MARKET rifled barrels, don't know why they replaced them would like to pick up the removed barrels, but they did.

I've read many accounts by new owners of CZ-82 pistols who mistakenly believed they chanced into a pistol with a worn/shot-out barrel, not realizing the barrels were in fact polygonal rifled.

I wonder if Century Arms made this mistake as well for a short time.

My cz 82 has a rifled barrel also. <shrug>

Ya'll have me curious now. I bought my CZ-82 via mail order and though I've cleaned it, I never really inspected the bore, though I had seen the "Don't worry, it's not shot out" warning over at AIM Surplus :).

Now I gotta go check the thing and make sure :).

(slightly) Off-topic: Is the longevity of a polygonally rifled barrel higher or lower than a barrel with "standard" rifling?

Higher.

Not that it matters in a pistol.

The CZ 82 9x18 barrel is also chrome lined to add to it's life span and ease of cleaning especially with corrosive ammo.

Lets hope it's not 9x17 barrel. The only difference between CZ82 and CZ83 is proly the barrel. Shooting 9x18 in such barrel would lead to disaster.
If this is .380 then $185 is very good price;) and ammo can be bought at Walmart for $2 less then 100 pack of .45ACP FMJs.:eek:

PabloJ, you can't chamber a 9x18 in 9x17 barrel - 9x18 is thicker.

Boris, you give our rednecks and general idiot WAY too much credit,
if it doesn't work at first, get a bigger hammer.

that said, I know many people who shot .380 out of a 9mak, cause.... IDK, and I don't think they did either, as they claimed, it was the same, and that the gun sucked...

you got a fine weapon.. Is it 9x17 or 9x18 ?? Regarding resale the brrl is not an issue with that gun, as long as it shoots and chambers well

I agree he got a fine weapon but IMHO if he ever has to sell it it is worth less than a CZ82 with a polygon barrel. I would be pissed if I received one that had a replacement barrel.

Part of the appeal of the CZ82 is the poly barrel IMHO I would pay less for a rifled barrel vs a poly.

I agree!.....Some may like the rifled barrel though, if they they're gonna reload cast bullets.

However, I do think that's a shady practice to not specify that it has a replacement barrel. Is it the distributer or the dealer? I don't know but either way it's BS.

CAI is the importer...

Yes, CAI is the import marks on mine also.

I wasn't trying to insinuate the dealer put the barrel on. I'd assume it's the importer or the exporter doing that. If it's the importer and they don't mention that to the dealers, well :rolleyes:

Hell, my dealer had no idea they even had poly barrels till I mentioned it to him. He really didn't know much if anything about the CZ-82s till I asked him to order me one. He bought several of them at that same time though, to resell. I doubt the OP's dealer is to blame here.

Yes, it is a 9x18 Mak. Says on the slide and the bullets chamber fine. I am dissapointed that is isn't poly but I didn't know it was supposed to be until after I bought it.

Its all good if it fires you will be fine. If it was me I would have sent it back. I have a C&R so no transfer issues would have come up for me. If the seller advertised it as a poly barrel I would ask for a replacement or some money back. It might not be worth it if you have to pay for a transfer.

Thanks everyone! This seems to be the biggest forum for a reason! I did not have to get it shipped, and he never advertised it as poly, so I will let it slide. Its a good deal regardless I think. Now if I ever go to sell it I will have some info on it.

I just bought a CZ82 with a US made barrel*for $239, same company was offering an original with polygonal barrel for $199. I don't know if I get the better deal or not, I will be getting another (poly). I am very inexperienced anyoneone have inpput on the barrel differences.

Unless you are a reloader who wants to shoot unjacketed lead bullets through your gun, I don't see the reason to get a CZ-82 with a replacement barrel. Polygonal barrels have a longer life and are supposed to be more accurate. Having the original barrel also increases the collectors value of your gun.

Even with Unjacketed lead, it only matters if you

THEN (as in after shooting lead, WITHOUT CLEANING THE LEADING)

Shoot jacketed bullets

I passed the first time I'd seen one because of this, then I learned it was called "oval" rifling. Different than polygonal rifling -- you can clearly see the lands and groves in a polygonal rifled Glock or other gun.

Use the search, there are threads about it here.

Great little pistol enjoy mine, but I got it mostly for the unusual barrel. If you put a bore light in the chamber and "walk" the reflection up the side of the barrel you can see it "spiral" as the bore diameter changes to make the twist.

When I was ordering at the JG site I just assumed the slightly more expensive one would be better for some reason ( a naive assumption). As it was the the thing arrived almost 100%, tiny bit of finish wear on left front of slide. It gave off lots of oil, leaked in fact. Does the CZ USA versions of the same gun have different barrels from the the surplus ?
I was going to get another one. Considering the difference in accuracy should I ditch the one I have an get a couple of polys ? Being an army brat, FMJ is shorthand for ammo and is all I have ever used over .22 cal.

The Polygonal bore was a design feature as it was supposed to use a light Sintered IRON bullet, with would and does eat conventional rifling, and is loaded about 25% hotter than standard mak ammo (if you see a PA 63 with a eaten bore it was probably a package deal with 9x18 vz.82 ammo)

As for accuracy, it is one of the most accurate pistols I have shot, even my brother did well with it. And most of his gun time is programming them in computer games.

If the box in this photo (found on http://en.valka.cz) represents sintered iron ammunition, then I'm certain I put many through an IJ-70 about a decade ago as I recognize the box and may still have some.

I believe the bore on the Russian commercial Mak was chrome-lined and perhaps that saved it from complete ruin, but I probably ran a couple hundred through that Makarov (that I no longer own, so I have no worries).
It's nice to learn new things; I had no idea these weren't typical lead core... I simply presumed they were corrosive and cleaned accordingly.

How common is sintered iron ammo now ? If I bought what 9x18 that commonly available to shoot in my new barreled cz82 will it damage the rifling ? Is this replacement barreled CZ82 a pig in a poke ? The discussion is leading me to think that I have to shoot premium ammo through the non poly barreled 82s.

Everything you're going to find on the net will be fine. Realistically a TON of that 9mm Mak ammo you see is going to be shot through PA-63's, P-64's, and regular old Makarovs, none of which are designed for the oddball "sintered iron" rounds (which you're unlikely to ever encounter). The reality is that the majority of guns out there have conventional rifling and they work just fine.

You should be fine to shoot whatever you want.

The sintered Iron is still made and USED by the Czech Army...
But due to Clinton, it is banned as "armor piercing" Ammunition, and therefore no long importable to the US.

So In the US
I would say it's pretty rare to find a small amount of a relatively obscure caliber, that was imported 15-20 years ago, and NOT SHOT in the said 15-20 years...

HUH
first, I have yet to find any true military surplus 9mak
second, most of it is either made by 'boutique' manufacture like Buffalo Bore or Hornady that manufacture high end defensive loads, OR from MAJOR EUROPEAN MANUFACTURES, who, much like Olin (Winchester, lake city and a few others) also manufacture for their countries defense industry.

Any Ammo in a colored box is fine, if you find a cardboard box like that ^^^^^^^, that says "vz. 82" on it,
and has brass cased BLACK BULLETS That looks like the above, BUY IT
then sell it on the Internet to a guy like me for 2-3x what you paid...
as we would love to have some of the 'real' stuff to go with our gun.
