Anyone tried this with a Glock 20 magazine?
I don't see why this wouldn't work. Lonewolf finally has these in stock. I have bent in the lips on the KCI 45 mags for 10 mm with success.
The KCI mags are a little fat in the quarter circle lowers. But they work fine in the pistols.
I ordered one to try out. Once it gets here I will let you know how it works with my G20 and G29.
I hope they work. 27 rounds of 10mm for my G29 would be fun. :o
I will. I will also try it with my G29 10 round mags. They ship a spring that is designed to work with the "full-size" magazine body, so it may not work well with the shorter G29 body.
There's a fellow that makes a good instructional video on YouTube on how to make these. Look up Alabama Arsenal.

Who cares. Put a x-grip on the top of your full mag part and stick the whole thing in your G 29.

I agree.
But, I was responding to this:

Since it is a 17 round extension, this implies that Blades doesn't have any 15 round mag bodies. For folks that don't have existing 15 round bodies, this would be nice if it worked with the 10-rounders.

The OEM G20/21 10 round mags are very different, body, follower, and spring. The metal case is creased inward into a narrow rail inside (making it single-stack-like), with a more narrow spring to fit. I don't see how the extender kits will work, without an extended spring designed for the G20/21 10 round mags. The G29/30 mags are different yet, so someone's gonna have to try that to know.
Yep, I was pretty sure this would be a no-go with full size mags limited to 10 rounds.
Which comes back to what I said I would test. Glock 29 10 round mags with the extender, giving a Glock 29 27 rounds.
I tell you I have had very bad luck with G20 Arodondo and Glockmeister extensions. I bought two of each, and only one of each of the 4 works with any reliability. Makes me not trust such extensions...............yet I remain wanting to try those!
These are supposed to be rock solid with Glock 21's. I read several reviews. No one had tried them yet with a Glock 20 and written about it that I could find.
Those reviewers echoed your experience with other mag extensions for Glock.
I found this site that has the KCI 45 and other mags for interesting prices!

Mine is out for delivery today...So, pics before bedtime.
Too tired for pics tonight. It installed according to directions and held 33 rounds. However, the spring is too wide for the 10mm mag body. It rubs enough that I don't think it will feed well. Gotta figure out how to squeeze the spring down some of make our buy a new one.
Sorry, this update isn't the pics either. Family is waiting for me, so this is quick
Spent about an hour total this morning including testing. Started by flattening each end with water-pump slip jaw pliers. This introduced a spiral into the spring, which I had to un-kink back out. When I was done, the spring would pass easily through the G20/15 round mag. I also spend some time with a file on the bottom opening of the mag. Factory is .800", which the G21 mag is .900 at that point, and the Kriss extension body is also .900. I opened mine up and round the edges.
Feeding from the mag with my thumb, there is still a slight hiccup as the follower transitions from the extension body to the Glock. I will work on it some more with files, then sand it up smooth.
All said, I think this is a workable solution for a 32-33 round magazine.

That video details in a very verbose fashion exactly what I learned over the last 18 hours. I went a different route on fitting the spring to the follower. I re-wound the top of the spring to match my G20 mag spring. And my vice would not mash the spring quite as easily, so I had to manually adjust the first 10 coils or so.
But, after buffing out with some 120 grit sand paper to get rid of file marks and smooth the transition from the KRISS to the G20 mag, it had-feeds just fine. I will make every effort to get a range test in in the next week or so.
The promised pics.
The first pics shows in the bottom two rows of parts, the KRISS body, liner and spring which come in the kit. The third row shows the follower, mag body and floor plate from a factory Glock 20 15 round mag. These three parts will be re-used in the KRISS system.
The top row shows the factory G20 15 round mag spring and insert, which are not used.

Clearly not a concealed carry option. But, great for my carry bag. I am gonna order up a couple more after I validate they run good. They will replace the three 15-round mags I currently carry in my computer bag.
Wow awesome. THANKS!!
Very nice let us know how they function, will be interesting. You had better work out a little build up some arm strength...step up to the press you gonna need more ammo! ;D
I did this mod for G20 last year....works like a champ.
This is a no-go for a G29 10-round magazine. The angle of the base plate to the rest of hte magazine is different than a 15-rd. Not much, just a few degrees, but enough that they 10 round body doesn't seat properly in the sleeve.
In other news, if the magazine spring from the KRISS magazine gets away from you during disassembly and propels the base plate into your monitor, you will need a new monitor. Don't ask me how I know. it is too soon. :-\
Someday I will laugh. Not today.
