Oh yeah sorry I mixed up my words, the 10 round ones that are for capacity compliant states and Canada. I think they also sell a 13 round one but this one just has 10 vertical slots for ammo countSingle stack? G21 mags are staggered, double stack. They come apart like every other Glock mag, but if they have never been apart, they can be a bear.
It uses this interesting limiting mechanism where there are ridges on the inside of the mag body. They are not quite single stack but less double stack than the regular ones. These limited ones only show 10 holes vs the reg capacity mag with 13 holes.Single stack? G21 mags are staggered, double stack.

Do you have a picture of the magazine? I'm guessing your magazine looks like the magpul 10rd mags for the Canadian market where you have to pinch both side of the mag to drop out the large baseplate assembly.Anyone have a special trick with these? I have the 45 acp 10 round magazines the single stack, no luck getting the base off. Usually I use a punch and pinch the sides, that’s what works with my normal and extended ones. Any advice would be appreciated!
