Wow, that looks like it's in great condition! Any idea how old it actually is? Interesting that you have it in 9x20mm, as I have a book that says most of them that were in the US had been modified to take .380 ACP ammo instead. However, it doesn't say if the ammo capacity is different that way like the 7.65mm ones(8 round mags). I'm assuming the .380 ACP ones take the same amount(7 rounds) as yours does.
Nice piece of history you have there!!! :ugeek:
