Really?! I wouldn't have thought that 9mm ammo would work in a .40 S&W magazine.
I had to try it while posting this and just did. The 9mm ammo looks like it's really wanting to just slip through those feed lips. I'm not sure I'd use the .40 S&W mags with 9mm ammo for anything more than practice, like the other poster advised. I'll have to try this at the range to see how it feeds.
