Glock 23 gen 3 mags vs. gen 4 mags?

[Rush2112]

Will gen 3 mags work in a gen 4 G23?

[Posit]

Yep - but the Gen 3 mag doesn't have cutouts required if you reverse the mag release button.

The Gen 4 Glocks have a 'reversible' mag release. If you reverse the release and install it on the right side, you need the newer mags which have a cutout on both sides.
