Let's say it is summer time and you have to store your gun in the car for an extended period of time. It can get pretty darn hot in a car, maybe upwards of 120 -130 degrees. Is this going to harm the gun and/or ammo? How long can the gun/ammo be in that type of environment and be OK?

There are going to be a lot of variables here...

Steel or polymer framed gun?

In direct sunlight or indirect heat?


I would think that a steel gun, even in direct sunlight, probably wouldn't have much of an issue.
I don't know enough about the composition of the polymers they use to give you an answer about those.

I'd just keep the gun reasonably insulated (like wrapped up in a towel or jacket) and under a seat or etc..., out of direct sunlight.

I'd wager that the ammo would have issues before the gun would.

Peace,

I don't see any problem with them being left in the heat, either steel of polymer frames. When I lived in SW Oklahoma the daytime temps in the summer would run between 90-110 degrees, so you can imagine what it would be like inside a car. I left guns in the car with no probem to the gun. Now you might want to make sure the AC as been cooling it for awhile before you try slipping it into the waistband. It will definitely burn you if you do it too soon!!

Although 140 deg F is a lot for a human, it is not that significant for mechanical devices. During extended firing sessions, parts of guns are designed to get pretty hot so I wouldn't worry about it in a car. Just don't burn yourself if you pick up a hot gun...

Keeping it away from extended direct sunlight is a good idea (UV radiation is bad for wood and plastic). Remember ammo discharges when it reaches about 450 deg F.

So long as you don't leave a gun in the trunk in Death Valley during high summer, yes, it should be fine.

If you've never experience truly hot weather, it might be hard to believe. But trust me, though: in 124* heat (near Death Valley), the inside of a car parked all day gets far, far hotter than that. Depending on what you use, a gun's lube can go very thin and start flowing right off the gun, in such heat, leaving the gun dry. Won't happen on a 100* day, but I've seen it happen once out in the desert. Had a rifle and gun in the trunk, while carrying my sidearm. Came back and found the guns in the trunk to be dry as a bone. Had to strip/lube them before they could be used.

Guns can go dry during extended sessions. Gun parts are designed to take the heat. But, lube goes thin. No part design is going to stop that, with some lubes.

never had one of my "plastic" guns melt and I normally rotate ammo at the range.

Why don't you send your question in to mythbusters.
