Glock magazine splitting

[kidicarus13]

Has anyone ever seen a Glock magazine split like this? This is a magazine that I sold to a friend circa 1997. He has kept it loaded in a climate controlled environment all this time. I know it's an older generation magazine but I'm hoping that mid-1990's Glock polymer is not prone to this type of deterioration. Thoughts?

I'm not sure how a magazine goes from 'just fine' loaded in a climate controlled environment to that in 18 years while being completely undisturbed.

But I've seen crazier things.

Any idea what rounds he had in them?

It was used before I sold it and it did/does have a +2 extension on it + a Wolff extra power spring. It did not look like that when it was sold to him.

I also know that the mag had not been dropped on a hard surface.

Never seen that before. However i'm sure one might hear glock mag horror stories here

Looks like pressure from the inside, OR like it was crushed from the side.

That is an old non full metal lined glock mag. They were prone to splitting like that. That is why glock switched to fully metal lined mags.

Maybe the mag was squeezed while putting the +2 on, my memory is not that good.

I've heard of Glock taking pity on folks a few years back, and warrantying them. At least Glock has some of the least expensive factory mags.

I'm not implying or trying to infer anything, just reporting what it looks like from photos.

Can't say I've seen one either. Damn.

It'd be worth seeing if Glock will replace it.

ETA: Seems it's been know to happen to other folks as well.

The cracked mags all seem to be the U-shaped mags like yours.

I Googled "older glock magazines cracking" and got tons of pictures of exactly the same thing, even with FML mags. It obviously happens, even with Glock Perfection.

I was looking at some of my older mags that aren't cracked but I did notice some weird "swirl" paterns from hole to hole as seen on the left column of holes on the third mag from the left...

I'm willing to bet that is where they will eventually crack...

[Wulf202]

I posted about this somewhere here. Its going to happen with any first gen mag left loaded

Sucks that it cracked. Probably darn near 20 years old anyways. Toss it and spend the money on a new one. Maybe the new one will last another 20 years or so.

While that is possible right now in CO with a 15rd mag, imagine being in a state (or point in the future) that doesn't allow new mags over 10rds. Although I understand the "mags are consumables" theory, we are getting to a point where that might become problematic.

You read my mind. I have a mix of metal/plastic AR mags.

Pistol mags are all metal (Sigs) except for some extensions. I have replacements for those.

I am more worried about a loss event though. There is nothing in the law that allows me to repurchase mags I owned in the event of theft/fire/etc...

That law needs to die!

[kidicarus13]

The magazine is a 15rd + 2 so I guess ow it's, according to Colorado law, a 15rd magazine. When this happens to a G17 mag it won't be such a simple solution.
