CDNN has some asian military super extended cap. glock mags. they had them in 9,40/357, .45. so i ordered up 3 for the .45 and bent the feed lips in to match my factory g29, and g20 mags. they feed flawlessly. i took all of them out to the woods after work and filled them to capacity which by the way is 31 rounds.

fed fired and ejected 100% proper with 10mm rounds, when i switched to 9x25 they would only feed right if i loaded 25 or less. but i am not hosing away with no 9x25's anyway.

here it is


9x25 setup below


the mags were only 18 bux, and like i said just three or so light but firm hammer stikes on each side is enough to hold the 10mm in there just like the factory mags. get them while you can!!!!

her it is, it is a little

I have one of them. It's the 27-round .45ACP magazine. I have LOVED mine for my G21SF. It's the KCI Korean mag that everyone calls crap. Mine has been amazing. It has 1,200 rounds through it with two FTFeeds. The second was my fault. I didn't fully seat the magazine. Here's the one issue with those mags. That time I didn't fully seat it, I fired the first round, it fell out of the gun, and it blew apart! The base plates are not well designed, and do not lock on well. If you drop it fully loaded, the base plate's coming off. Mine came off, dumped the remaining 26 rounds on the ground, and launched the spring about 50 feet off into the woods. Luckily, GTRhino saw where it went, and we found it. Other than that, it's been perfect.

I loaded mine up with 10mm and tried it once (they will just barely hold 10mm rounds as they come stock). It held 31 rounds and worked about 70%. However, I didn't bend the feed lips. I might buy a few more to modify. They are built well, despite the bad reviews. They look just like Glock mags on the inside. They are fully metal lined, and made just like the Glock mags. They are INSANELY hard to load to capacity at first, and come with grease inside them. If you buy one, wipe the grease out, load it to capacity, and leave it for a few days. After the spring takes a set, they are easy to load, and work perfectly.

Here are some pics I took with 10mm loaded up when I first got mine (July):

Do the Magpul Magex 17 round extensions (13+17=30) that attach to 13 round G-21 mags work on G-20 mags too?

Update: There is a review of it on the Top Glock web site that says the spring is too short for the G-20 mags. Wolf gun springs does not make a spring for this extension.

any mag accesories for the g21/30 work on the G20/29

this is just a range mag, and a reloads for the Apocalypse.LOL

FWIW, i tried 2 of the 3 i modded for the 10mm, and every single round feed fine.

i was thinking use the 27 rounder, add the mag pull thing for and extra 17, then addapt a kriss 15 round extension. add some pogo stick feet on the last base pad, and i could effectively ride my glock like a pogo stick.

id shoot the gun on the decompression stroke of the "pogo mag"

these are jokes.......maybe.

hell. anyone with a g21 owes it to themselves to try oune of these mags out. they do work.

as 21carrier said, they are INDENTICAL inside, from the shape and placemtent as well of mounting of the metal insert, dimmensionally they are the same. they drop free. whats not to love.

anyone should try them before they automatically brand them as "unreliable"

I just got a couple more in the mail, makes nine for me. I just cant justify buying extensions when they cost more than a mag does from b0tach...
That's where I got most of mine as well. I started with 2 and since joining GT, I now have a total of 8. I'll probably get a few more and call it quits. 10 should be plenty.....damn this forum makes me spend a lot of coin!!

I agree. Mine has been perfect in my G21SF. Notjustanothermini, have you LIVE FIRE tested yours, or just hand-cycled them? I say that because mine would hand-cycle 10mm fine (without bending feed lips), but was only about 70% reliable in live fire testing.
