Title: Can this Glock 21 magazine be modified for 10mm?
Post by: Pablo on January 02 2016 09:19:45 PM MST
Is there a mod to make a G21 magazine fit a G20?

I doubt it. But I want it.  ;D

The magazine will fit, you will need to bend the lips at the top to hold the 10mm.

It's as easy as that?

Well, sounds easy, but will need to hold the 10mm round "just right". It may not be 100% reliable, but may make a fun range toy. The follower may need to be swapped out also, just thought of that.

sqlbullet - are these adaptable to 10mm? How tough is it?

Bit of dremel work and some work with pliers.  They work great once done.

Here is the thread on the subject, starting on Page 2 where I describe what I did.  Dizzy Dean posted a link to a you tube video on the subject as well.

I have 4 of them now.  That is how adaptable I found it.  I can fit 32 rounds of 10mm in them.  Added together with my nine 15 round mags and two 10 round mags, + 1 each the the Glock 29 and Glock 20 tubes, I have 285 rounds ready to go in Glocks.  If I grab the Para's and Witness's I can run 500 rounds before I have to reload.

Is there a link? I'll search for Dizzy Dean.

Sorry, meant to paste that link.  I went to the work of finding it, then apparently forgot to ctrl-v.

That video covers it weil.

It's even simpler than that. My two mags came today. Just a gentle squeeze with my medium Knipex and the mags feed my Glock 20 perfectly.

If had known this option existed I would not have bought the GG AR lower. Oh well.

The magazine holds 31 rounds of 10mm.

Capacity depends on how much you squeezed the springs.  Before I did anything, my held 33 rounds, but the spring would hang up when it entered the Glock 20 body.

After I removed the lip with a file and bent the springs, mine hold 32.

Good to know. I obviously haven't shot mine yet. Nice option for the price.

Wait. Are we talking apples vs. oranges? What lip? Why mod the spring? I THINK you are talking about the mag extender. I'm talking about a straight up Glock 21 imitation mag, modified for 10mm.

Yeah, apples to oranges.

I used G20 mags with the extender and got 32.

Can this Glock 21 magazine be modified for 10mm?  - YES

Finally got the Glock 20SF-L to the range. The full extended magazine popped in perfectly. The balance seemed natural. And with 30 rounds of 10mm on a longslide not super heavy in hand. The magazine fed just fine.  (I was fighting with the slide jamming back, so no rapid fire).

All I did was slightly tweak the feed lips in.
