Hey Gunnutz,

We finally had some time to do a run of Glock 21 +0 mag extensions. These fit all the full size Glock 10mm and .45 ACP pistols.

As always these are Canadian legal +0 magazine extensions. That means you can add them to your magazines without having to re-pin your mags! Installation works exactly the same as a factory Glock magazine and uses the factory retention methods so you can be sure they will never fall off during use. Other than making your pistol look awesome they also make fast mag changes a breeze! The extra length makes seating a full mag on a closed slide easy, even with our 10 round "Canadian" mags.

Our Glock 21 mag extensions also fit the Glock 20, 20SF, 21SF, 37, 40 and 41.

We also make Canadian legal +0 mag extensions for almost every model of Glock pistol, CZ-75, Shadow 2, Tactical Sport and Czechmate, Sig P320 and more. Head over to our website to have a look around!

Those look amazing. Are they going to be a stocked item or just done in limited runs?

We will keep them as a stocked item.

Since we manufacture all of our own products in house it makes it easier to keep them as regularly stocked items. Sometimes we do run out of stock but we do our best to get them back in stock as quick as possible!

Thank you,

Are these like the oem ones with metal sleeves on the inside ??

Hey SoftBoys, I'm not exactly sure what you're referring to.

Our mag extensions and base pads mount just like the factory Glock base pads. They use the normal Glock mag insert, not the Glock mag extension insert. If you have a Glock mag with the thin plastic base pad, then these will be a direct replacement.

If you have any questions, please let me know!

Thank you,

Sorry disregarded. I read it wrong, thought your company made a a glock 21 mag with 10 rds with no pins plus the plate so it feels more flush . That's why I ask abt the metal sleeves inside as oem mags have them vs other companies made out of plastic like ets . I just quickly read it and miss the important information which is a base plate. The picture threw me off lol.

Will these fit on Glock 20 and Glock 29 mags

They will fit perfectly onto G20 mags and be inline with the mag body.

For the G29 however, they will fit onto the mag but since the bottom of the mag is on a different angle, the mag extension will not be inline with the mag body.

If you have any other questions, please let me know!

Thank you,
