G18 Magazine In "Regular" Glocks?

[Jelly]

Wouldn't this work just fine and give you over a thirty-round capacity?

[JohnKSa]

Identical.

[Jelly]

Thanks John.

Is this a common modification made by Glock owners?

[jesse485]

It most certainly is. Usually for HD use and range use as the mags are a tad long for carry, even as a back up mag. One of these days, I'm gonna get one for range use. I'd use it for HD, but my gun is a .40 cal, and the 9mm conversion barrel is only range reliable (99%).

How would inserting a mag in a mag well constitute a modification?

[WillBrayjr]

It doesn't. The nice thing about Glocks, the magazine are interchangable. The 33rd G-18 magazine will fit all the 9mm Glocks.

[JohnKSa]

Is this a common modification made by Glock owners?It's commonly done but I also wonder--How would inserting a mag in a mag well constitute a modification?There's really no modification involved to either the frame or the magazine. The G18 and the G17 use the same frame. In fact, ANY 9mm Glock will accept magazines from the higher capacity 9mm Glocks.

In this case, one could argue that the "G18 magazine" is really an extended G17 magazine that also fits the G18. ;)

I like having the ultra-capacity magazines. In addition to the Glock, I have 30-round magazines for my S&W 59 & 5906 and Beretta 92F along with 20 round magazines for my 1911. They are even somewhat functional for CCW if carrying the gun in a horizontal shoulder rig.

[WillBrayjr]

The G-17 and G-18 do not have the same frame. They are designed differently.

[JohnKSa]

Interesting--I didn't realize that. You're right, the frame rails are different. It's only done to prevent parts interchange between the 17 and 18 as far as I can tell...

Anyone know of any other differences? As I read it, if the frame rails were NOT different, one would be able to put a G18 slide on a G17 and have a working machine pistol.

[Hkmp5sd]

The magazines are the same though. :)


I wonder why they have different rails yet Glock makes a conversion for the 17 to make it full auto. Why not just make everything interchangable?

According to Jeff Cooper as well as myself and others, to hit what you are aiming at is much more important than the big hi caps. Why fill the air with ordinance ifyou can't
hit what you are looking at?

[JohnKSa]

to hit what you are aiming at is much more important than the big hi caps.Sure, but being able to hit what you aim at more than 30 times without reloading is better yet.

HAVING 17 or 33 rounds on tap doesn't obligate you to put them all in the air.

Also, I find it amusing that there's always this assumption that having a hi-cap gun means one can't shoot. Having a hi-cap gun doesn't make one a poor marksman. And having a lo-cap gun doesn't make one a good marksman.

[WillBrayjr]

HKmp5sd,

From what I read there are slight internal differences so a G-18 slide could not be installed on a G-17 frame making it full-auto or vise-versa. In other words a G-18 slide will only work on a G-18 frame.

[JohnKSa]

a G-18 slide will only work on a G-18 frameWill,

The rails on the G18 frame are raised slightly and the slots milled in the G18 slide are also a bit higher to match. That makes it impossible to get an 18 slide on a 17 frame. But at least one source implies that if the rails were NOT different, one could turn a G17 into a G18 by simply swapping slides.

[WillBrayjr]

That was trying to say :rolleyes:

[Zekewolf]

Glock does not make a conversion for the G17. There are aftermarket f.a. kits available, but are generally not legal in the U.S.

HKMP5SD: Where did you find 20 round 1911 mags that are reliable? I've never found any over 10-11 rounds that would function as intended.


jesse485: I think Sherer makes 29 round .40S&W mags for the Glocks.

[Hkmp5sd]

I came across some stainless no-name 20-rounders at a gun show just before the '94 AW ban went into effect when people were making >10 round magazines for every firearm they could think of.

With a 33 Round Mag for a Glock 17/19/26, who needs a Tec-9. The Glock system is much more reliable. At least thats the way I see it. Plus it is more compact.
