Can handgun ammo "cook off" from a hot barrel?

[black22rifle]

Is it possible for a handgun to cook off a round from a hot barrel? I always wondered about this while at the range. I usually shoot around 300 rounds when I go and at times I like to practice my draw from appendix. It makes me a little bit paranoid.

If its hot enough to cook off a round it going to be way too hot to stick in an appendix holster, think glowing red barrel.

I think you need sustained full auto to get it that hot. Ignition temp is around 500F so if it's below that, your safe. You can't get a pistol that hot shooting semi, and reloading.

Unless your handgun is belt fed, no.

Even if you could get it hot enough to cook a round off, it would be too hot to hold onto with your dick beaters without burning the shit out of them.

So this seems to be a non issue to me.

There don't appear to be any cook offs here.

669 nearly continuous rounds on a Glock 17 with full auto sear. Other stuff starts melting down first.

In 6 1/2 years in active-duty SF units, I saw literally millions of rounds go downrange. I remember ONE cook-off out of all of those rounds. It was in a badly maintained Thai M-60 on a very hot day, and the round sat in the chamber due to a broken extractor for several minutes before it finally cooked off.

Even in balls hot North Carolina summers shooting between 700-800 rounds and constantly holstering with a round in the chamber while I jam mags/tape targets/eat a sandwich, I have thankfully not blown my dick off from a round cooking off, nor have I ever seen a handgun actually cook a round off.

I'd be more concerned about burning said dick than anything else.

Slight hijack to the thread but....

Has anyone ever witnessed or seen the aftermath of an open breach detonation?

I think there is one at 4:40. His finger is off the trigger and it goes bang. I'm not a pro video reviewer and just watched it on an iPad, so I could be wrong. The video is fun to watch though! Thanks!

Howdy,

Might be possible with a Glock 18 and a dozen beta mags fired full auto.

Back in the "Day" I can remember rounds going supersonic when firing a suppressed MP-5 during weapons training. It usually happened after firing several mags pretty quick then letting a round sit in a hot chamber before firing it.

I just watched that a few times, and it's probably a cook-off. He was whacking the slide at the time, but I suspect it cooled off since if the striker assembly and safeties failed badly enough to send the firing pin home, it wouldn't have continued to run so well after.

[voiceofreason]

have run many many mags through a G17 as fast as possible wearing gloves with the metal burning hot; didn't cook any off toward the end when hands were tired and slower

[Ned Christiansen]

I agree, highly unlikely.

But I would not risk righty based on it..... why not err on the side of safety. Take a break and let it cool down.

On range days with the pistol we have cook offs all the time!!

They just take place after shooting when me and the wife are comparing ideas on how long to leave the lamb chops, t-bones or pork ribs on the grill...
