I was thinking of dragging it to the range just for shiggles. But, it's only got one magazine, I think...I'm not even sure how to tell 9mm from 7.65 magazines apart. Anyone know?

There are different spring strengths for the .30 and 9mm versions but I've been using them interchangeably for years without any noticeable isssues.

I've got a handful of Mecgars in 9mm, and a couple of original aluminum bottomed mags in 9mm, but my lone 30 Luger mag has a wood bottom...I'd prefer not to use it, along with the other 9mm luger mags I have with wood bottoms. Those all sit in a nice pile away from everything else.
