A Glock can't fire out of battery.

So the four people in this thread who made the suggestion it can, need to go back and have a close look at a Glock so they can understand how it actually works and we can stop crying "OOB" every single time someone has a gun blow up.

True OOB are extremely rare because the vast majority of guns are designed so they cannot fire OOB. When a gun blows up, most likely an OOB is the very last thing we should contemplate not the first.

My opinion it's a bad reload. We sometimes have issues accepting that it was us, bit unless you can 100% validate that your reloading system never makes an error, that's what it probably was. For you not to notice a sound error when a round blew out the bottom to me is the weird bit. I notice the change in sound from one powder to the next in my 3 Glocks.

I reload too but not a fan of tight group powder; it burns too hot and it's really easy to overcharge or double charge a case because you need so little of it vs other powders.

Ps never an issue with my 9mm loads and Glock 17

This is why I have mostly moved away from Titegroup and now use HS6 for most handgun applications. Nearly impossible to double or overcharge.
 
Had similar thing happen on my g17 the case had bulge . I did not see it when loading my magazine . Blew out my magazine when I pulled the trigger . Luckily I didn't damage my frame .

Apparently if you don't maintain (read clean) it properly it can/will fire before completely in battery. Not like all the way but partially due to the firing pin safety plunger staying in the "depressed" state.

I highly doubt that. The striker is maintained in an uncocked position. It is the act of pulling the trigger that "cocks" and then releases the striker. The striker plunger is somewhat irrelevant to that process. The striker plunger only prevents the striker moving forward in the event the gun is dropped muzzle down.

In my case the primmer was not flattened at all.

Well if your primer wasn't flattened then it certainly wasn't high pressure. Also if your primer corners are nice and round then I would suspect a high primer. Are you 100% confident that you seat your primers well? I always swipe my finger over the base of the bullet once all is done, if a primer is high or flush, I seat it further.

Quite possibly an overcharged reload but given the lack of full case support with Glocks it makes the overcharge damage potential so much greater. I have double charged my Ruger 1911, fortunately at minimum charge. It worked out to be approximately the proof load charge. There was no damage and I have since fired thousands of rounds through this gun. The lack of full case support really highlights any case weakness there may be.
 
Frames are serialized - I will be very surprised if the answer is anything but 'no'.

But! Just pick up a gen 4 model 20 and you can use your slide on it - then you have two calibers available.

Thk Lately I have been wondering why the strong opinions on something that is impossible to have happen. Ok, highly unlikely {read: never}.

The firearm behaved as per the engineering. There was an overcharge, the powder blew through the case where it is unsupported and the gas blew down enacting on the mag. It was likely the mag release's positive engagement with the mag that cracked the frame...there is a lot of expanding gas trying to get out in a hurry, in this instance the entire magazine was forced downward, had there only been one round in the mag the psi would have likely forced it to the bottom of the mag against the spring first; whether it would have only had the energy at that point to pop the mag plate off the bottom or still had enough potential to force the whole mag out we'll never know.

Because the vast majority of people haven't got a clue and don't want to bother to get one so they just blindly parrot back something they have heard somewhere that superficially seems to explain the occurrence. Same effect can be seen in the global warming mess.

A properly working Glock cannot fire out of battery, but shyte happens and sometimes things operate in ways they weren't designed to.

OP, could you try to measure how much of a case is unsupported in your barrel, and compare that to the blown out case?

No. A Glock CANNOT fire out of battery. It was specifically designed not to.

Once again, for those not paying attention, the striker is not under tension, not cocked until the trigger is pulled. The trigger bar doesn't contact the striker when the slide is out of battery. Thus it is impossible for the striker to be propelled forwards under spring tension when the gun is out of battery. Thats just the start. On top of that is the striker block pin which prevents the striker moving forward until the trigger is pulled, which pushes the pin up and frees the striker.

In the case of the striker block pin being stuck in the up position, and all the stars align perfectly, there is the remote possibility in the event the gun is dropped muzzle down the inertia of the impact could drive the striker forward and if the round has a soft primer etc etc the gun could fire in an out of battery condition. But this could NEVER occur from the case of the trigger being pulled, which is what occurred in the OP.

Is this something that has changed ? My understanding of Glocks were that you had to rack the slide to set the striker hence no second strike capability. I have Sigs and 1911's and revolvers so no experience with striker fired units. Not that this has any bearing on how this gun blew up. Don't want to derail but inquiring minds need to know.

Racking the slide causes the trigger bar to be reset. Hence no second strike without the slide being racked. During normal trigger pull the trigger bar draws the stiker back, compressing the spring. The trigger bar then drops down and releases the striker.

So it's a DAO trigger no pre-tensioning of the striker by the racking the slide?
