Gen 2 Glock 19 Question

[AR15fan]

I have an early Glock 19, Gen 2.

I’ve had it forever and it probably has 7500 rounds through it.

I’ve shot everything from Factory +p defense rounds to cheap relapse you buy at the gun show.

Lately - I’ve experienced case blow out. See attached.

I’m wondering if I’ve just been luck for 25 years of ownership (as I’ve never experienced this prior to this year) or if I’ve just gotten a crappy lot of reloads?

In short, is the barrel shot out? Or should I just stop shooting reloads? Crazy thing is I’ve shot these same reloads out of my Springfield Armory 9mm loaded and not had any blow outs.

This is not a 1911 vs Glock thread. Looking for some knowledge.

Thanks!

Gun is probably fine. You just had that one in a brazillion bad reload. Rare but it happens

So you think it's just a bad batch of reloads? This happens once every 30 rounds or so. But hasn't happened yet in my SpringField 1911. That's my only concern about the gun.

Most likely I'll just get rid of these reloads and shoot only factory. But it sure does sting when one of these cases lets go!!!

1 in 30??? Where did you get this ammo from? That is a ridiculous failure rate! Glocks are known to not have full chamber support but unless you can see an obvious defect in the chamber I seriously doubt it's the gun.

Thanks to both you guys!

I was already thinking I would just trash these reloads.

I ran 100 rounds of Factory (Magtech) ammo through it today with no problems. But literally one every two magazines of these reloads would rupture and blow the mag out of the bottom of the gun and sting my hands.

Not worth it.


Thanks!

Youre just limp wristing it.

I had a Gen 2 g23 before. Really liked the gun. I only shoot my own reloads. I noticed that the barrel didn't support the cases as well as Gen3 model barrels did. It left a bulge in most of the cases at the bottom. That's the only reason I sold it, because I didn't want to wear out my cases prematurely. Never had a blowout or malfunction with it though.

I would say you got a batch of reloads with old worn out brass, and the reduced case support of the Gen 2 enabled the cases to blow out. I think it's the brass, not the gun. Never know how many times the cases were reloaded before you got the reloads.

Glock chamber has less case support than the 1911 barrel by a small amount. Ammo sounds like the culprit.

If you are not getting the same failure rate with factory ammo its the ammo.

Out of curiosity I would measure a few of the re-loaded ammo case and see how they compare to factory loaded ammo. I wonder if they inadvertently used a .380acp sizing die to size 9mm brass, not sure its possible, but maybe, causing it be a bit undersized for your Glock barrel.

My thoughts...

There's tons of info on the net about Glocks bulging brass.
The bulge can be removed with a special sizing die but the case is still weak where the bulge was.
If the case is weak and then fired in a Glock style chamber again, it may fail.
I'm not bagging on Glocks here, I think this batch of brass was already worn out.

WOW, sticking a case like that is likely pushing 60,000 PSI or so!

... In short. This reloaded ammo is crap.

People who sell reloads are going for a profit. They get a bad case they will still load it.

I reload but the first step is case inspection and if it is cracked or well worn I toss that piece of brass.

Are they reloads made by you? Or did you buy them. If you bought them, please let us know from what company. So we can avoid them.

In my opinion, with 40 years of reloading experience, it was too much powder, wrong type of powder, worn out case or any combination.
