How to cause an out of battery discharge with a handgun (video and pictures).
I asked the question poorly I suppose. My question was/should have been, would a TRB have solved the malfunction? If no then the following thought is would it have produced the same effect (a round being fired)? If it hadn't fired then the next malfunction drill would have solved this.

It still comes back to me questioning yooper's modified technique as being flawed in my mind.

To try to quash yet another change in firearms terminology, “out of battery discharge” refers to the discharge of a cartridge when the slide or bolt is not fully forward and therefore the cartridge is not fully chambered. In that situation the cartridge can rupture because it’s not fully supported by the barrel chamber and can occur even with standard ammunition and normal pressures.

The term does not refer to having a cartridge rupture due to an excessive powder charge or other overpressure situation that causes the case to rupture even though the round is fully chambered. As Bruce Gray has demonstrated, it is virtually impossible for a true OOB discharge to occur with a P320.


Understood. Both of mine appeared to blow out the side of the cartridge and took out the right side of the frame module. I'm not sure how that could happen with a cartridge completely in the chamber but I'm no kind of firearms engineer.

"The designer of the gun had clearly not been instructed to beat about the bush. 'Make it evil,' he'd been told. 'Make it totally clear that this gun has a right end and a wrong end. Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with." -Douglas Adams

“It is just as difficult and dangerous to try to free a people that wants to remain servile as it is to try to enslave a people that wants to remain free."
-Niccolo Machiavelli

The trouble with fighting for human freedom is that one spends most of one's time defending scoundrels. For it is against scoundrels that oppressive laws are first aimed, and oppression must be stopped at the beginning if it is to be stopped at all. -Mencken

If a cartridge is chambered with the slide fully forward (“in battery”), it’s still possible for a catastrophic case failure to occur that will blow out the case head or web and vent gas down and into the magazine and grip. Sometimes the magazine and grip area are completely destroyed and the shooter can suffer some injury.

That occurs most commonly with overcharged ammunition and/or defective case, but could happen if there was a barrel blockage.

This photo is from an NRA article about the subject, and it shows what I’m referring to. That case web failure is much different from what is pictured above. Only the small, unsupported portion of the case is blown out as compared with a total rupture. It would be interesting to know what the cases looked like in your incident.

And I am not trying to be pissy about all this, but rather just trying to clarify some terminology.
