Can anyone identify this magazine? It appears to be a 9mm 7 round. I guess it could be a .380. I bought it at a flea market. It's built really well but absolutely sterile of markings. It had 6 rnd of 9mm in it, I didn't give any more than the bullets were worth. Thanks. I have the hardest time with pics. By the time it accepts them they are so heavily pixelated it's ridiculous.
