I said tell sig did not say anything about sending in the gun.
From other posts, it seems that other sigs are blowing up also.

Yup, if you don't know what you had, you don't know what you have.
I am very skeptical of the notion of "out of battery" firing in a gun with Browning tilting barrel lockup. By the time it is far enough out of battery to expose case wall, the firing pin no longer aligns with the primer.
I have a couple of range pickups that look like "out of battery" events. There is a light indent near the edge of the primer. Thing is, the bullet is still there, the cases are fine, there was no "out of battery" DISCHARGE, gun design prevented it.
Load was 3.8gr of w244.
I was wrong on the bullet weight, it was a 124 grain hoosier lead round nose.
Coal 1.05 to plunk in his shortest chamber.
Guess i was also remembering the velocity wrong, those were running right at 1000.

Well, that is a normal, even light load. If that was what was really in THAT round. But we have no way of knowing and getting a handle on it would mean pulling the rest of that batch of ammo down to look for overloads. And maybe not finding another.

LoonWulf, do you know when was your M17 made? I ask because I recently picked one up. I haven’t shot it yet, Im curious in the unfortunate case that I have an issue too.
I’m glad you weren’t severely injured.
Its not mine, but i know it was purchased in 2018
We kinda did pull em all down.......
Handloads using thinwalled economy brass, no idea of proper crimping to prevent setback (mil spec requirement IIRC) SWAG on what powder, projectile? Primer?
I've read these reports for over 20 years the one thing I never hear is the name of reloader, contact information, and wording on their guarantee for liability. In most cases its not the same name as the one etched on the slide.

Glad you are OK.
Purchased this RIA 1911 45 ACP new
It constantly ejected the magazine when chambering a round, or when shooting. I called RIA they sent me a new magazine release
With the new magazine release, the magazine was held too low. I could feel a bump, bump as rounds were fed into the chamber. And, chambering a round multiple times, the bullet would get seated deeper and deeper into the case.
One day, shooting ammunition that chronographs and shoots like this in the RIA
(I do not consider 800 fps loads high pressure in a five inch 1911)
a round blew a case head, blowing the magazine out, and stuffing bullets in the magazine, into the case.
primers look normal, but primer condition is very varible.
I wondered if I double charged the ammunition I used, and I shot up the rest of it without incident. I then loaded several hundred rounds more, with mixed cases, same primer, same bullet, but with 7.5 grs AA#5 and that load is just over 700 fps. I was super careful on my reloading procedures.
Shooting the 7.5 grs load I had an over pressure event, the slide jammed back, the primer was extruded into the firing pin hole, and that was the point I decided the problem was gun related.
I purchased an EGW extra high magazine release, spent an afternoon filing it to file my RIA 1911, and to date, the pistol is running well. Instead of a double bump for the cartridge going in the chamber, I get a single bump.
Don't discount bullet seat back. I do have my own chronograph data with a 9mm where the bullet was set back, and I fired it, and it was hot. Real hot.

Why would there be a name etched on the slide?

I just had a thought or a recall of arsenal loaded military ammo blowing up guns. IIRC the scenario towards the end of the powder reservoir used on the loading machine, a lot of fines from the power get loaded that is similar to range trash and that can take most any gun apart. This is from cases of .308/7.62x51 getting blown up from surplussed ammo.
Under rushed conditions even factory ammo could be dangerous when new production lines are setup and run 24 hours a day.

Was the case bulged and then "busted" before resizing?
Not that im aware of, tho i think these were rhe "processed" cases i got from one of the more prominent once fired vendors.....ill check and update if im wrong

In August of 2017, SIG began adding disconnectors to the P320's. It was also part of the Voluntary Upgrade Program. There was a class action pertaining to OOB's in 2018 and it was settled last year.
Does the gun in question have a disconnect?
That said, your photos appear to me to be a run-of-the-mill blowout which isn't uncommon in 9 Major. Shoot factory ammo and see if the problem persist.
The gun has never been back to sig, of that much I'm sure. I don't know if it has a disconnect or not.
Untill The beginning of 2020 pretty much all the 9 mm we shot was factory. Id guess we probably put somewhere close to 5 or 6,000 rounds down range from when the gun was purchased till we couldn't get 9 mm here.... not all was shot through the M17, but It was at every outing, so I guess it's seen at least a thousand rounds of factory ammunition.
Since we've been running hand loaded ammunition we're probably up to about 4 or 5,000 rounds processed and fired. Again a fair percentage going through that M17 and to date that's the only (near) catastrophic failure.

Glad all the digits are still intact and you’re ok after that!
Stay safe.

I am glad you’re okay @LoonWulf
One lesson that I learned here from your experience is that the reputation of Blazer Brass “brass” isn’t all that good for reloading. I have at least several hundred pieces of that brass mixed in with 3000-4000 pieces with other head stamps.
I haven’t had any issues, but…
I have a very strict rule of not shooting other people’s hand loads in my guns. I used to buy remanufactured ammo years ago until one day I got some that had numerous light loads and one pretty stout one. That day was “lesson day” for me. No more after that.
I know you said it wasn’t your gun, but still, they are “reloads” regardless of whether they’re made by a buddy on his press or from a company that sells to the public.

I too, am glad you’re okay @LoonWulf. Been there, done that in my CZ P-07. Blew out the slide stop, safety and spring, and the mag out of the gun, and there were some light powder burns. All the parts were right on the bench, and the case was stuck. At home, I drove out the case, reassembled and all was well. I attributed it to no case/cartridge gauging in my reloads leading to an out of battery situation, but ever since, I gauge all my loaded rounds and have had no further such incidents. I had not given thought to bullet setback, so I guess this too could have been the cause???
