Cook off temperature ~151 degrees Celsius = 303 degrees Fahrenheit.

Basically only firemen have to worry about guns and heat. Although for them it is a real concern.

There is no minimum temperature concern. At least nothing any of us would live through. Maybe at 300 below the sear might shatter or something. But I doubt even that.

Yeah, unless the firearm is being left on the dashboard, it should be fine. As for cook off temp, bullets are firecrackers outside of a a chamber. almost zero danger to anyone, but it'll chew up your gun.

The problem is you likely keep your car gun with a loading magazine in it.

Lube has the potential to thicken up in extreme cold and slow down moving parts. It’s not going to break anything, but can affect reliability under certain conditions.

Both of my trunk guns are doing okay, one polymer lower, one aluminum lower.

Phoenix.

No optics on them. Just flipup aluminum sights.

The ammo should be able to take almost anything except being submerged under water for extended periods. Keep your gun oiled, some lubricants can evaporate off in the heat.

I used to be worried about this too. But then I realized that the US military conducts operations in the middle east where it can get over 110+ degrees F and they probably don't keep their huge stock piles of ammunition in air conditioned units either. Yet I have never heard about US soldiers getting injured or killed when ammunition randomly exploded due to heat. So if ammunition doesn't blow up randomly in the middle east, it won't blow up here either.

As far as winter goes, you could get condensation on the gun and ammo if it is cooled overnight and then warmed when you start your car. This condensation can cause rust and probably damage the ammo over time.

Best not to leave your firearms in your car. They can get stolen more easily that way and they don't do you any good. Keep your handgun at your waist. Your rifles are better at home than in your car.

It gets hotter than that inside the crew areas of the abrams tanks and we never had any rounds cook off in there.

I thought so, but I didn't want to exaggerate. Man that must have sucked to be in that tank. Thank you for your service.

Summer temps are 100+ for a lot of July and August

I doubt I'll ever understand why people live in such places. "Wait, summer temps are 100+ for a lot of July and August? Goodbye hellhole!"

Everything i want to do is within a 2 hour drive. You get used to it after a couple years.

Edit: Also, I don't need a jacket for half the year.

I remember being drenched with sweat at 8 am, with -20F during the winter. Tolerated it until I was old enough to move. Now I'm just generally intolerant of inferior stuff and people across the board.

That's most of the US right now. Where do you live?

Close enough to the pacific that patches of fog are coming in and overhead right now (7 pm). Temp is 65F. IMO, the most perfect weather and location combination in the US. Granted, it is the "most unaffordable" place to live, but I'm not interested in hardship just because it's cheaper. I did live in horrific weather conditions as a kid up into my 20s (-20F in the winter, +100F at 95% humidity), so I'm quite familiar with what that's like.

Those 100+ degree days are my favorite part of the year, pussy. Fucking 100% humidity too.

You're welcome to them. I lived in a place like that until I got old enough to move. If you've never lived in a nice place, you should check it out sometime.

For some reason... That makes me remember this:

Good evening, I would like to begin by introducing myself. My name is Hydrogen, and I come from a low-income neighborhood where life is not very comfortable. I have stolen many things and been in many altercations, most of which have ended in gunfire. In addition to this, I have had sexual intercourse with a great number of the opposite sex. In contrast, and despite the lack of legitimate evidence, I believe you to have been involved in a fair amount of homosexual activities; activities I and my companions look down upon. I am so much stronger than you, and my powers of rhetoric so much greater than yours, that you could employ an army of some sort to aid in your fight with me; but I, of course, would prevail because I am stronger than you. I'm sure I needn't remind you of my place of birth, wherein as I explained before, the living conditions are much worse than in your aforementioned city of residence. I would like to stop here for a moment and remind you that I am orating with little or no prior preparation (an act commonly referred to as "freestyling"). Once again, and I think this bears repeating, I would like to restate my claim that I am, in fact, much stronger and have endured a larger number of hardships than you; hardships that have left me with aggressive behavior and an imposing demeanor which I believe frightens you. I know of a woman with whom you have had sexual intercourse. I too have had sexual intercourse with said woman, and she complained to me of your less-than-exemplary performance in bed. She went on to explain to me, in graphic detail, the dimensions and particulars of your genitals; and I tell you what she said was NOT very generous, sir. In conclusion, I would like to leave you with a brief summary of my argument: you, sir, are a weak, timid, and untrustworthy homosexual.** The city in which you live is not nearly as difficult to live in, nor is in such a high state of disrepair, as mine.** I am the superior monologist in this debate, and any claim to the contrary will result in physical violence and perhaps even death.

And a good day to you too, sir. I would like to rebut your previous claims in an improvisational and rhythmic manner. I was given the name Boost by my peers. The alleged "facts" you have uncovered in regards to me are unfounded and without merit. My birthplace is not only vastly inferior to yours, but my neighbors are much more resilient. In terms of your claim to my sexuality: Sigmund Freud theorized that in some cases the semiconscious mind manifests repressed desires, therefore leading me to believe that you, sir, are indeed the homosexual. In fact, I once had a romantic rendezvous with your biological mother in which fellatio was performed forthwith and without explanation. The encounter lasted several hours, and many unspeakable acts were implemented. I paid her for her services and no subsequent contact, either verbally or physically, has been made. I brandish a nine-millimeter pistol which I stole from a man involved in a gang related turf war. I fired the pistol several times and, in some cases, critically wounded those with whom I was in contest with. I would like to inform the audience that I engage in the sale and consumption of illegal narcotics on a regular basis. Speaking candidly, I am in no form intimidated or fearful of your actions, as I have been involved in countless altercations which have ended less than favorably. In summation, your argument denotes a lack of intellectual honesty on your part. It is my contention that this matter would best be solved with fisticuffs; I believe I will be victorious in this regard.

Rap battle translated.

SHOULD be fine. I used to have to do the same. Granted the hottest I have ever seen in Indiana is 115F. Usually the heat around here is between 95-100 in the late summer.

I keep two pistols in my truck. My usual appendix carry and my backup, shtf "I'm fucked" pistol. One is polymer and the other is solid steel. Both have been fine.

Few studies that cover this it might reach 160F inside the car after a few hours in 95* outside temp if the car is black with the windows fully closed. If the ammo cook off really is like 300+ like people are saying I doubt even a 115F day would get you within 100F of the cook off temp.

What about polymer parts of the gun, do they warp in the heat?

Due to where I work I have to leave my gun in my car all day

Who lets another person or group people/corporation tell them that they can’t arm themselves even to conceal? Come on, seriously? Put that gun on your waist and protect yourself like a man.

Schools. Government contractors. Military bases. Many places. I assume this person at least slightly likes their job.

Concealed is concealed. To others, it never exists. But to you- it does to save your life.
