Glock Magazine Sizes

[particle]

Let me start off by saying I don't own any Glocks and have never really had any interest in them so I know very little about them...

I'm currently offering holsters for Glock 19/23/32 and Glock 26/27/33 models, and am about to order dummies for the G36 and G17/22 models. My question is this - if I'm making mag pouches for these guns, do I need to have a different magazine for EACH model? Or are the external dimensions of each group of Glock mags the same, so I only need one mag per "cluster" of guns? I see Rings sells a dummy magazine for each and every different Glock model, so I'm assuming they all have different external dimensions but wanted to ask the good folks of this forum before I place my next order.

Particle: I have had pretty good luck getting demensions from the guys on calguns.com.

Also I have called rings blue guns, the tech dept there has been very helpful in giving me info as they are very aware that their guns are being used by many holster makers. You might give them a shout, I'm sure they will help you.

I had the same question not to long ago. I found this thread http://leatherworker.net/forum/index.php?showtopic=25035&st=0&p=158535&hl=+mag%20+pouch%20+glock%20+mold&fromsearch=1entry158535

"If your pattern is not too tall, you can make the same mag holder for the models 17, 17L, 19, 22, 23, 24, 26, 27, 31, 32, 32, 34, and 35 (and I believe the 37, 38, and 39 as well) off of one dummy mag. Another dummy will be necessary for models 20,21, 21SF, 29, 30, and 30SF. The model 36 will require a dummy mag all its own."

Thanks! I've seen that post, but forgot all about it. I appreciate you tracking it down and linking to it.

Using that information, along with the dummy gun list from Rings, I added a bit of information to the model table. Basically, "H1" means "Holster Pattern #1". Likewise, "M1" means "Magazine Pattern #1". Can anyone provide any clarification off-hand regarding the models with an "X" for the pattern indicator? Will those guns/magazines work with any of the other models?

Yes, I'm a geek. And bored - I'm out of leather.

G20 is the same physical size as the G21, uses the same sized mags. G29 is the same size as a G30, and uses the same size mags. For all practical purposes, the 20/21 is the same gun with a different size hole in the barrel. Same thing for the 29/30. Yes, Im a Glock freak.

+1 to what woolfe said & linked to. Just to add a little something though...

A 9mm Glock mag will fit into a .40 cal, or .357 Sig Glock pistol of equal or smaller size (and vice versa), but just out of curiosity I did some measurements with my calipers awhile back. I found a small (but consistent across a decent sample size) difference in size between 9mm & .40 mags.

Note: Height was measured from the tip of the forward end of the mag follower to the underside (not the very end) of the base plate (i.e. the dimension of interest to a holster maker).

9mm

Width - .9"

Length - 1.309"

Height - (G17 = 4.4") (G19 = 3.9") (G26 = 3")

.40 S&W

Width - .9"

Length - 1.3"

Height - Same as for similar 9mm frame sizes

Although the difference is arguably insignificant, the .40 mags are slightly smaller in length (the bullet length dimension). With that in mind, I use a .40 mag (G22) for all standard frame Glock mag pouch making. I just drew two silver sharpie lines on it that correspond to the smaller mag sizes.

On the .45 GAP and .380 pistols, I am 99% sure that they are the exact same size as their 9mm, .40, and .357 Sig counterparts. They are pretty rare though, especially the .380 which isn't sold in the US. If you ever get a holster order for one of those pistols, mark it on your calendar, cause it likely will never happen again.

The G29 & G20 are the exact same size as the G30 and G21, respectively. I am also 90% certain that the .45 ACP SF "slim frame" models only differ in the length of the grip (i.e. the bullet length dimension), and that all other dimensions are the same. Thus a holster made for a G21 or G20 should fit a G21 SF (and vice versa)

FWIW

Thanks for the input fellas! I have updated the graphic based on the information y'all have provided. If anyone sees any mistakes, please feel free to let me know and I'll update it in case this graphic is of benefit to anyone else.

I can confirm that the G36 mag will not fit in a pouch tightly molded for a G22 mag. The G36 mag (single stack) is somehow fatter than the G22 (double stack).

One other little nugget that may or may not be of any help - I made a couple of mag pouches recently for my CZ 75 Compact 9mm 14-round mag and a coworkers G22 (.40 cal), and though the G22's mag was just slightly thicker, the same pattern worked fine for both.

Im just nit-picking now, but the SF designation is for "short frame" The difference is from the backstrap to the trigger, it has about a 5mm shorter reach than the standard model. Some of them have ambi mag releases. Some of them have picitinny rails in lieu of the Glock rail. Everything else is the same. 10mm and .45acp have the same cartridge OAL. The biggest snafu when building a 21SF holster will be the rails.

You're right. I even knew about this common misnomer and still got it confused. At any rate, at least were on the same page for what it means. It's good to see confirmation that it is only the grip length along the bullet axis that is different, as I may need to build a holster for a 21SF in the near future, and I own a G20 to use for molding. As far as the rails go I think I'll be safe using the G20 with standard Glock rail for making a holster for a Glock with a picatinny rail, there just wont be molding depressions in each picatinny notch when the 21 SF gets holstered. Although using a picatinny railed pistol as a holster mold for a pistol w/ standard rail might result in too tight a fit. That's my thought anyway.

When you said that 10mm and .45 ACP were the same OAL that sounded wrong and prompted me to look it up. I load for the 10mm but not for .45, & I was curious more than anything. Not only were you right, but the max COL for .45 is actually longer than for 10mm, 1.275" vs 1.260 according to LEE's 2nd edition. Go figure. I would have expected the 10mm to be longer than the .45 to about the same degree the 9mm is longer than the .40. (1.169" vs 1.135").

Take care

Can anyone confirm that a Glock 37 mag carrier can be molded with a Glock 19 mag?

Ive never had my paws on a 37 or it's mag, so I cant go over 99% certainty.

I buy stuff from these guys all the time...
