Here we have a very rare Interdynamic KG-9 semi auto open bolt 9mm pistol with aftermarket threaded barrel. These guns did not come threaded from factory, and I have not been able to find any others online with a threaded barrel making this possibly 1 of 1. The threaded barrel is removable. Only 3,000 of these were made before the ATF sent their letter of cease and desist on grounds of the easiness to convert to full auto. The value only goes up on these as the years go by.

The barrel's thread pitch is the same as a MAC-10, 3/4 x 10, so you can run a stage 2 Mac suppressor on this. Pictured is a fake suppressor for a the 9mm mac series, I just put it on for representation, not planning on including it in sale.

Condition of this gun is overall very good, it does have a bad area on the pistol grip, some light to medium scratch marks. They don't seem to be very noticeable to me, and almost seems like you may be able to get rid of them if desired. The gun has some minor light scratches in a couple other places but overall its in very good shape. Pictures tell the tale. Viewing the internals it looks to be shot very little. I polished up the bolt some when I got it, looks very nice. No box unfortunately, just the gun and magazine.

Price is $3,500. All cash offers considered. Feel free to ask any questions you may have, if you'd like a photo of somewhere specific I'd be happy to take them.

No trades, cash only. Don't want to sell but am in need of cash. If it doesn't sell on here it will be going to GB.

Very cool 8ps relic. I love the notch at the rear of the bolt slot . It's kinda like the safety on a Sten. Plain old run of the mill 9ps Tec 9s are getting close to a thousand these days. So this open bolt model should sell easily.

thanks, its been for sale for awhile. Looks like it'll end up on Gunbroker, was trying to avoid that but haven't gotten much interest in it on here. Well, everytime I update the listing someone comments on the roof shingles..... not even on my roof but people can't help themselves from commenting about it lol
 
Well ...I noticed the shingles and thought maybe it was on the dog house. But IF I was in the market for an open bolt it wouldn't bother me. It's definitely a relic from the good old days when the gun industry was wide open.

Yeah back when a polymer or plastic lowers were a brand new concept. Hell the ATF was ok with these guns (they were approved) but after criminal elements started to melt the serial numbers off with a hot butter knife and mark up the bolt to make them dump the mag in 1-2 seconds they sent their cease and desist. Interestingly enough, ATF never outright banned in writing the open bolt system. Current manufacturers decide to not push the buttons due to the letters ATF sent to RPB and Interdynamic back in the early 1980s.
