Archived [ARCHIVED THREAD] - Will Gen 1/2/3 Magazines Work in a Gen 4 Glock 21?
Posted: 1/12/2021 2:06:38 AM EDT
I know, look it up on the internet.  But I got two different stories by doing this. And so I return to the source of firearms knowledge, ARFCOM.

So will Gen 1/2/3 magazines work in a Gen 4 Glock 21s?

Not an issue.  Also not sure there are necessarily generations of G21 mags.

Yes they will work as long as you don't turn the mag release around to the right side of the gun.

There are 20+ iterations of Glocks mags.

If you want to identify Glock mags for G21 using "generation",
all G21 mags will work in a G21 gen 2 through G21 gen 4.
ETA: Not 100% true but 98% true. It's very doubtful you will
hit 2% category LOL.

There is NO G21 gen 1.
