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 http://i1214.photobucket.com/albums/cc482/notjustanothermini/DSCF7333.jpg

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

Think you can find a link to this treasure? I'm only able to pull up some 27 rounders for the Glock 21...hoping I'm not too late.

I'm guessing 27 45acp rounds equals 31 10mm rounds because the 10mm are narrower.

I have a couple of these for the 45, have ran good for me. Great at the range when I can load at home and shoot the whole time I am there. Might have to play with one and see if I can get it to feed for my 10s.

Awesome then. I was concerned about the Glock 21 magazines 'locking in', or whatever the proper word is, to my pistol.

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):

if you notice in the first pic, i put a factory glock base pad on with the locking plate. it still holds 30 rounds also.

how bout a KRISS +15 on the bottom of one of these. 45+1.

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"

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.

How heavy would 31 rounds of, say, 200 grain loads weigh? Does it affect the balance much?

I'm not sure about 31 rounds of 200gr 10mm, but 27 rounds of 230gr .45ACP feels really good. With my G21SF loaded up with 27 rounds, the balance feels AWESOME! It's like having a pendulum hanging from the bottom of the gun. It is balanced almost right on the trigger. If you put your finger under the trigger guard, where it meets the grip, it will just balance on your finger. I think it feels really good.

yes hand cycled both 10mm and 9x25, the tens's ran fine. the dillons set the bullet back every last one i tried, ruined 9 ultra expensive 9x25's.

i didnt live fire the 9x25's due to the fail of the hand cycle, but.. i did live fire 2 boxes of underwood 165g JHP's and all ran fine.

the mag seems to kinda want to open the lips back up, so i did some real tweaking to them to make them sit lower than they should, after a mag full the lips were perfect and arent opening up anymore.

we should be going out riding atv's today, as i was too sick to work. i had the "shoot gun fever" so i called off. ill try to make a video of the big sticks function. as well as the glock, ill have the MAT backup 10mm, and the megastar out also, maybe. but the glock and amt will be for sure. also i will bring the cz rami subcompact with a ruger p95 30 adapted for it as well as a p95 30rnd made for a sig pro 2022

I've modded the kriss mags for the 10mm. there is a problem with the transition between the extention and the mag body. additionally you MUST have a slightly thinner width spring to fit into the 10mm mag body correctly. would be a custom deal.

If I remember correctly we would probably need a whoel different setup for it to work, but a spring and a modded follower and beveled mag body would probably go a long way towards making the kriss magex work for the 10mm.

Have to play with the 27 rounder KCI tho.

who sells those?

12-06-2011, 20:41
notjustanothermini, its a shame you're not close by I would fix those 9x25's for you!
Set back could be a serious issue. I would tap them back out to the proper length with a kinetic bullet puller...if you took your time you might be able to do that just to be able to shoot them.

Hey if you have 9x25 brass you don't intend on re-loading, contact me about possible deal.

notjustanothermini
12-11-2011, 15:03
oh yeah with a bullet like the 9x25 i am not risking shooting a setback projectile.

i tried yanking them with a pair of channel locks and a vise, but i didnt want to smash up the bullet.

i did order a bullet puller.

Notjustanothermini, Be sure to measure the COL as you tap them back out easy. It would be nice if you had dies to re-crimp them. If you don't have dies maybe you could find some one with 357Sig dies that could re-set the seating depth and crimp of you. While you can really load the 9x25 properly with the 357Sig dies, it is possible to seat and crimp using them if you are careful!
Best regards!

i am on the fence of getting a complete lee setup.

i doo need a press as i shoot 10mm alot. and also i would like to shoot 9x25 more also. only way to feasibly shoot 9x25 in any volume is with a press.

Seems like you gents had better luck then me. Went out this morning to try my G20 with 30 rounds in my extended mag. I was only able to fire off 4 rounds.
Each time I shot, the magazine would fall out under the recoil. The 4th time the magazine blew apart. Never found the internal parts. Maybe the temp played into the failure, it was 25 degree's here in PA.

Merry Christmas and Happy Hanukkah to all !!

i used a 20" MAC 10 9mm spring in it, a two pack a machingun.com for 18 bucks. you all had to be wondering what spring i used, right? i know i was wondering on what spring i would use.LOL

i ran 37 rounds through it, i just wanted to see if it would feed past the "sepreation" of the mag body and the kriss extension. it did.

i also beveled the bottom inside of the 30 round mag body. and also used graphite powder rubbed into the mag body and follower untill they looked gray.


no to get that carbine upper....

That's because the notch on the mag body, where the mag release would grab, is not a deep and sharp edged notch. Look at how sharp the notch on 15 round mag is, then make it similar with a sharp tool. The full weight of 27+ round is too much for it when there's a recoil shock. Basically, the Korean mags are of inconsistent quality, sometimes rounded notch, so you'd have to fix each one.

Mine was a rounded notch, too.

To blend the KRISS mag extension with the Korean extended mag would require some major mods to the Korean mag, and I am satisfied with 30 rounds anyway.

Silly place put the mags on sale after I order 3 of them! lol

10 -10mm mags should get me by.

I like the Korean mags better than the Glock mags with the KRISS extensions on them. Easy to modify the feed lips to hold 10mm ammo. Will be turning the Glock mags to original length with the plus 5 Arredondo extensions (shown on the regular 15 round mags, bumping them to 20 rounds)

The KRISS extensions are headed to ArmsList.

Only two problems I can see...

THE MAGS ARE KOREAN!

YOU HAVE TO HAMMER THEM INTO SHAPE TO HOLD 10mm ROUNDS!!!

No thank you. I'll put my $99 toward standard mags or ammo and range time. I put my garbage out at the curb every Wednesday night if you want to dig around for some more junk. :)

I have 2 that came today. Bent the lips in. Then warmed the plastic around the lip to form to the New angles. Also had to clean the inside of the mags. Excess plastic snagging the carrier. Hand cycle great.have to shoot tomorrow maybe.

Loading that many rounds is a work out. My ccu comes next week or the week after. These will be my mags

Try a 10mm follower instead of .45acp if you have any problem. followers are about $4 each. They'll fit and run fine. Put a tad of Frog lube on the inside wall, hair dryer to warm and soak it up.

I heard they do have a surplus of 10mm CCU but they'd have to call the waiting list first. This means your CCU comes sooner rather than later.

They had no barrels. That is why I have waited an extra 4 weeks. Barrels came in last week. They were backlogged in the 10mm dept. Catching up now.

I will try the 10mm follower if it has issues. I don't think it will. Really cycles great by hand.
