Glock blows up

[Che762x39]

This was shown to me in person at the shop I go to.

Thank you for sharing.

Glock warranties a lot of stuff, even if ammo related, so I would venture an educated guess and say yes. They may warranty it free of charge or charge him a couple hundred dollars. I've seen it both ways.

It was my understanding that reloads void warranties.

So some idiot blew up his Glock with a bad reload. How does this have anything to do with Glocks and 9mm vs 40? Could happen with any cartridge or firearm with the wrong powder or overcharged round.

Just in a Glock, or any 40S&W gun?



.

in any .40

to be clear, I am not saying that .40 can not be safely reloaded - what I am saying is that .40 is all that forgiving, especially when compared to 9 & 45.

if you look at the pressure curves the .40 shoots sharply & abruptly straight up where as the 9 & 45 are more of a gradual curve.



***so I googled looking for some links to pictures of the actual charts & found some interesting pictures;

this one was fitting

a bit amusing

and then just what I searched for

A more appropriate thread title would be 'hand load blows up in aftermarket barrel, Glock saves the day with containment'.

You're not supposed to reveal all the information in the title.

this is actually why I try to discourage people from reloading 40 - the pressure curve is more of a pressure spike & you can go from safe to catastrophic failure in no time flat.

Correct. .40 powder, especially in heavy boolets has a Bell Curve that is unforgiving in small mistakes in powder charge. You are spot on.

Is it fair to state that most kabooms came from .40 caliber?

Yes, mainly because the G 22 was the choice among police departments and more guns equals more reported problems.

BTW that can be completely fixed.

Haha.... Funny stuff

owner didnt pay attention to a squib load?

More likely an overcharge IMO.

I was gonna say .40 + Titegroup but I won't...

Yep. You know and understand.

Yee campaign manager?

Haha...that would work..

Early on since the 90s Glock had a few problems with reloaded range ammo. Mostly because these police departments would buy reloads for practice in .40 caliber. The problem was the reloaders didn't realize that the .40 powders were very sensitive to mistakes in weight. More and more Kabooms in the .40 caliber were reported. Over the years, Glock changed the barrels to a tighter support at the 6 o'clock position, where most case failures happened.

See this photo:



I have to agree with Quiet. This aftermarket barrel was a KKM. About .007 thousandths tighter than a factory Glock barrel and considered a very good barrel. To blow up like the photo indicates, it would have to be a double charge.

Reloading .40 you have to pick a powder that fills the case and makes a double charge Obvious. But some powders that are fast only fill the case 40% and a dangerous double charge can go unnoticed.

This is why we know this was an overcharged case. I reload 10 MM and we pay attention to case support in various barrels. I purposely run powders like AA # 9 and Longshot that fill the case to avoid double charges.

Here are some barrels with case support that is obvious.

You are a wealth of knowledge Bob!

YAY!!!! FINALLY, someone that doesn't want to tell me that I am full of s**t and that they load .40 all the time and never had any problems... and that because they never have had an issue, that it safe for everybody.

I have a tendency to actually listen to older, much more learned people what have all told me to stay the hell away from .40

Supposedly Federal makes their 40 S&W brass cases thicker to better resist bulges and blowouts. I have not cut one in half and compared it to Winchester or Remington. Speer, and Blazer, brass are owned by the same company (ATK) that owns Federal, and their brass is all made on the same machines except with different head stamps, so I think Speer, and Blazer, brass is also thicker. I Use Federal 1x fired police range brass to reload 40 S&W.

All the money saved on reloads and, oops, time to pay for a new gun...

[Bill Steele]

Here is my take:

It wasn't bullet setback.

It wasn't a light overcharge.

It has nothing to do with the aftermarket barrel.

It has nothing to do with 40S&W being any more dangerous to reload than any other pistol cartridge.

It was almost certainly a double charge.

A less likely chance, but still a chance, is it was a light charge (squib) that had enough energy to drive the bullet past the throat (not just a primer only thing), and then the shooter racked the slide on what he thought was a light strike and didn't realize only an empty case was ejected, then chambered the next round and kaboom was the result.

That was a big kaboom, by kaboom standards.

PS - If you think you can't get a double with factory ammo, a guy over on the GT forums just posted a story about his brother shooting a double charge with some WWB factory ammo. The extractor came off the slide and struck him in the eye, which he lost. But I will grant anyone that there are a lot more kabooms with amateur reloads than factory...

Improper reloads will blow up any pistol. I am not defending Glock because I don't like them but it isn't the pistol's fault.
