Somewhere in the middle East, that's for sure.
For years, the only pistols we saw like that were those brought back by the few tourists who visited those areas. But today, we have thousands of soldiers in that general area who are banned from bringing back enemy weapons as souvenirs, but who have money and want some kind of firearm as a trophy. The result is an influx of those guns, ranging from ones made as serious firearms to guns that could not possibly fire and were never intended to. FWIW, I think that one might fall into the former category, but it is so crude that no attempt should be made to fire it.
