Round Cookoff

[papaSR9]

Not that this happened nor have I heard this occur with a chambered round, except maybe for the news story on a woman storing a weapon in a stove.

I went to the range this weekend with my two sons and we went through two hundred rounds apiece with my SR9 and SR40c. The SR40c is my carry so when we got back to the car, I racked my carry magazine and chambered a round. The gun was still noticeably warm and as soon as I holstered it into my IWB holster I thought in the back of my head that I have a 'hot' gun confined between my body and jeans with little or no ventilation. Not thinking that it would happen but also not being the first test case if it did, I upholstered the 40c and cleared the chamber and put it in the side pouch of the drivers door to let it cool off.

I am not sorry if this sounds stupid or extreme but I error on the side of caution but thought I would post it here to get some opinions on just fired pistols and chambering a round afterwards.

The barrel would have to be way too hot to touch to even come close to a "cook off'. If it was that hot, you could not have holstered it comfortably.

well, if a hot gun were to be a cause for a round "cooking off", don't you think there would be more than a few million reported cases of the same from the battle fields of the last century or so?

Not so stupid. Anything for safety's sake is a valid thing to consider.

I witnessed a cookoff once. M-60 Machine gun which had been firing (demonstration on a range) for a while when a jam occurred, leaving a live round in the chamber and an open bolt. Round cooked off in a few seconds, sending the brass flying out the chamber (not sure where the bullet went, if it left the barrel or was stuck in it) and hit the guy standing next to me in the calf. It left a little welt, but did not cut his pants leg or skin. He did jump pretty high, though.

Primers can cook off at a lower temperature than gunpowder, I am told. About 540 Fahrenheit according to this video

There are others. Just do an internet search for "Primer Cookoff" and similar terms.

While I have literally blistered my trigger finger on the frame of my 44 Redhawk after a very quick USPSA 32 rd short field course, I am not aware of any handgun 'cook-off'.

I have seen an M16a2 cook off a round. The devil dog was told to get rid of several hundred rounds(500-600 IIRC). He put the rifle on burst and started running mag after mag through his weapon then kaboom. That's the only one I have ever seen and I have been blistered by machine gun barrels. I wouldn't worry about it.

1*, do as you see fit. I can't fault ya.

Error on the side of safety is not an error! ps

As noted I have never heard of a gun being hot enough to cook off a round except full auto weapons fired continuously enough to probably ruin the barrels. Im not sure it would even be possible to get a manually operated gun hot enough through continuous firing?
