I carry concealed, however I work in a state building, and need to keep my weapon in the car.

Is there a danger of a discharge due to the heat that may build up?

I don't worry about ammo blowing up, but I do worry about the powder and primer components degrading and becoming unreliable with constant exposure to high heat and/or frequent heating/cooling cycles.

That, and the possibility that lubricants may become liquified and run into places they'd best not be, like grease or oil getting into magazines and maybe penetrating ammo, making it unreliable.

Any other thoughts out there? There ought to be at least one other handgunner around this ghost town today...

No need to worry. Ammo wont go bang from getting hot in a car. Needs instant super heat, like in a HOT chamber of a rifle, to cook off. Gradual heating will not detonate the round. Even if the powder would ignite, the lead in the bullet will melt long before the powder would go off, and would run into the powder. Not to mention that the jacket alone wouldnt let the powder create enough pressure to launch it very well.

DScott did make some good points about the lube though. Just be careful about it and dont overdue it when lubing the gun up as it will become much more "fluid" when hot.

Your biggest worry is that hot ammo can cause the chamber pressure to skyrocket.

The cycles of heating and cooling are generally not going to cause a problem with modern propellants. In any case, after a few months, I like to shoot my mag of carry ammo and replace it with fresh rounds. Haven't had anything unexpected happen yet, and my ammo gets damned hot indeed in the Memphis summer.

Even here in Ohio, guns or ammo left in the sun can get too hot to handle, on the range or in a vehicle. So I can't imagine Arizona! Maybe its time for someone to invent/market a cooler just for such occasions? (watch next month, over a million sold)

I have a little minifridge thats about a foot and a half tall and a foot wide than cools and heats.. that plugs into a cig lighter or into a wall
