As the barrel comes out of battery, the chamber drops down.What makes you say that? If the chamber is in spec, and the majority of the case is in the chamber, the firing pin is going to strike the center of the primer.

That's true but by then it should have disconnected.As the barrel comes out of battery, the chamber drops down.
True. But, if working correctly, the barrel will drop maybe a 1/16 of an inch before the trigger is disconnected. If timed correctly, the web of the case is still in the chamber with the exception of Glock manufactured barrels. For a non Glock barrel, assuming it is in spec, the pistol timing has to be off quite a bit to have an OOB ignition.The barrel and slide can only separate after the barrel has dropped.
If you look at a bunch of semi-auto, 9mm barrels, most are some form of unsupported, with some worse than Glock factory barrels. Plenty better, sure. But almost all lack some support in the feed ramp area of the chamber.True. But, if working correctly, the barrel will drop maybe a 1/16 of an inch before the trigger is disconnected.

They always look like this. Glock on the right.That's true but by then it should have disconnected.
This guy nailed it.If you look at a bunch of semi-auto, 9mm barrels, most are some form of unsupported, with some worse than Glock factory barrels. Plenty better, sure. But almost all lack some support in the feed ramp area of the chamber.
Yeah, an OOB with a glock would take disconnector defect or a double feed.This guy nailed it.
People look for all sorts of explanations that blame OOB or double charges or whatever. What OP had happen was a brass failure, and the failure point was probably at the feed ramp area of the barrel. Most of my guns won't even fire with slightly high primers. The likelihood that it went OOB with the case that far out of the barrel seems implausible, to say the least.
I've had brass blow out maybe 2-3x like this. If you habitually collect your 9mm brass and keep re-using it, it's going to happen. For the most part, I don't collect pistol brass because of this.
Is that true of the 9x19 Glocks? I know that the 40 chambers were revised some time around 2009 maybe. The dot in the hexagon on the barrel, indicating the revised chamber. I've never heard that the 9x19 chambers ever changed, nor that they ever had any issues with support.Outside of maybe some custom fully ramped bbls ( with the protruding ramp sticking out behind the bbl , and corresponding notch cut out of the frame ) , every semiauto will have at least a scooch for feeding .
Glock ( particularly 1st Gen ) simply has more than most .
Off the top of my head , up to 7 factors have to be just right ( wrong ) to have a case blow out. Glock chamber ramps are just a small factor , on just one of them .
I do the same thing at the range. I never pick up my own fired reloads to reload again. There is so much 9mm brass laying around and I just pick what other people leave laying under the assumption (and also my observation ) that most are firing factory ammo. If you belong to a range of any size and reload for 9mm you should never have to buy brass (except for some special loading) because there is so much free brass available.If you look at a bunch of semi-auto, 9mm barrels, most are some form of unsupported, with some worse than Glock factory barrels.

That said, I collect so much range brass and shoot so unoccasionally in comparison to what I collect, I might never worry about it. That said, I am mostly just not collecting my shot brass for 9mm. Most range trips I end up collecting 50-200 pieces of 9mm brass. Sometimes more (rarely, I'll skip collecting any brass or find any brass to collect).
About 1 in 2 trips I am shooting 9mm. And usually 50-100 rounds of 9mm a trip, sometimes 150. I've got about 1000 pieces of cleaned brass ready to load. About 1200 rounds loaded. And I've got a 2 gallon bucket filled with 9mm brass and another 2 gallon bucket maybe 1/3rd full. All dirty brass (mine or range brass). My math comes out to around 4000-4500 cases between those buckets.
I shoot probably 1200 rounds of 9mm a year. So I'll likely never run out if I just trash what I shoot.
Even with somewhat specialty stuff. I've got about 200 +p nickel plated cases W-W and around 140 FC of the same.I do the same thing at the range. I never pick up my own fired reloads to reload again.

Yes, I do collect my own 45 ACP cases for reload as that is a much lower pressure round; you'll probably lose them before they are no longer safe to reload. I wish more people shot 45 ACP at my range.Even with somewhat specialty stuff. I've got about 200 +p nickel plated cases W-W and around 140 FC of the same.
Not sure I really need it marked +p, but hey, I can load one or both up for rolling my own XTP loads.
Even 45acp, I don't collect much, but I still usually walk away with 10-40 cases a range trip. I do pickup my own .45acp, but I still probably collect as much as I shoot. Add in collecting some of my own and my 45acp brass collection keeps growing.
Lol, ditto. That and Euro 7.65 browning/.32acp.Yes, I do collect my own 45 ACP cases for reload as that is a much lower pressure round; you'll probably lose them before they are no longer safe to reload. I wish more people shot 45 ACP at my range.
