Hello to all, I need yall's help

[p89ruger_9mm]

I have a mag a friend gave me, he got it with some other gun stuff from
he's friends family. He's friend passed away; my friend knows nothing
about the mag. I'm sending you all some pics. The mag(single stack) had some 4 or 5 380's in it. It looks to be a 10 + round mag.
I've asked everyone around gun friends, gun shows, gun shops and still no
luck. There aren't any proof marks on it. I haven't tried any Makarov
rounds, I think they'd fit. I'm not sure if 380cal dimensions are the same as 9mm Kurtz (I'm checking into that as well) I've tried every brand of pistol( old and new) with a bottom handle mag release. I measured and mic'ed( mm &
inch) the mag so that it might help identify it.
This is a puzzle I haven't been able to solve. Any help would be
greatly appreciated.

Thanks
Mark H

could we get some digital pics from a couple of different angles?

The 9 x 18 Mak ammo is 1mm longer than the 9 x 17 9mm kurtz, aka .380 auto. Could it be from a Bersa? Or an extended Walther PPK mag or something?

Here a comparison Picture

I use to have a Bryco 48 (junk) and I found one of my old mags. If you look at the length difference were the mag catch is it tells me the mag on the right has a much longer/larger handle on the mystery mag
