[ARCHIVED THREAD] - 357sig Glock mag-will .40 work in it?

Posted: 4/19/2017 5:16:27 PM EDT

A friend of my daughter's recently bought a glock 27. I have an old Glock 31 mag I'm gonna give him, will .40 work in a Glock labeled 357Sig mag? I know in Sig Sauer it's the same mag, wasn't sure if Glock is the same system.

I use 2 of them in my G27...By accident I bought them in a bin of used mags & didn't notice. The follower is different but they seem to work fine.

If you compare the two mags, you'll see that the only difference is the follower.
Loads and feeds interchangeably. I have several 357sig mags for use in my Glock 23c and they work without a hitch.

Some people report the .40 follower isn't 100% with 357. I've never had a problem with my .40 mags at the range so I never fooled with the followers. The issue seems plausible so I do only use 357 mags for carry in my G32. I've never heard any issue with .40 in 357 mags.
