Glock 40/9mm mags interchangeable?

I have heard you can use Glock 40 and 9mm mags in the opposite gun. Is this true?

Sure is.

Just dont put 9mm mags into a gun with a .40 chamber unless you're absolutely sure you've got the 9mm conversion barrel in there...

I ran my G19 with a 10 round G23 mag and had 1 to 2 malfunctions per mag.
