Hello everyone. I'm looking for a flap-style magazine pouch for the 21 round P320 magazines. Any recommendations? Thanks!

Off the top of my head I’d think a 20 round colt 9mm (Metalform) pouch would work pretty well, just about any 20 round 9mm pouch SHOULD work depending on how the baseplate fits.

Hardest part is gonna be finding single ones. Most comes 2/3.

Search for mp5 or p90 stick mags.

I know tactical tailor makes them as well as first spear. And I’m sure there are about a million airsoft options if quality doesn’t matter as much.

This TACO might work, since the flap is adjustable via a buckle.

Midway USA has their brand 6 mag pouch that is about $13.

I have some 5.11 tactical VTAC pouches that work with both the 17 and 21 round P320 magazines. It uses a Velcro flap.
