Hello

My question is concerning a cold gun. I have a P3AT that I use for my CC. Living up in the north( Cleve Oh) I have on many occassions the need to leave it in the car when I go out. ie: , work, restaurant/bar etc. Is it safe to fire when it is cold?. Will it damage it if I had to fire in a SD situation while the gun is cold?

Thanks, Dave

There was another thread a week or two ago where this same thing was brought up.

The opinion of the masses was that the cold shouldn't hurt nothing. Think of all the many things in your life made from composit or plastic that are in a freezer or in your car that are used in very cold situations.

I think it's safe.

Can you, or someone else, give it a try somewhere and give the rest of us a report? I can see grease on the rails causing some problem if it gets stiff.

Hello,

Having shot Kel-Tecs in cold weather in (Springfield OH) I can say the P3AT was not hurt. I'd lubricate it with a light teflon water displacing oil though (rem oil, Break Free CLP), as condensation from going in and out might cause some problems if it gets really cold.

Best Regards

I've shot mine in the cold many times. Living in the greater KC area means we get some harsh Winter temperatures. Our high last Friday was 1 above zero. I also use Tetra gun grease on mine with no issues.

I think this is a good question......

I would not worry about grease, material can have a very significant change in theIr properties with temp.  I would not shot a wood stock rifle below freezing.  walnut is more likely to crack.

metals, especially hard metals, have a property call ductile to brittle transition temperture.  a very strong steel at normal temp, becomes brittle in icey ocean water.

I know I have seen DBTT charts in my referance handbooks, but I can not find any thing good with google tonight.  I did find one chart that shows sae 4140, and it looks interesting.  a very quick brittle transition near 0 C

Besides asking if it is ok to shot a P3AT in the cold, the question that would mean the most would be "what is the DBTT for the barrel steel.

btw, polymers also have this trait

You know, living in Cleveland myself i've been wondering this same thing every time i come home from work after my p3at has been in my car all day long.

I live in N.W. Indiana right at the tip of Lake Michigan where it gets really cold, and my p3at stays in my truck at all times if it's not on me. I went to the range 3 days ago, and shot 100 rounds through the p3at without a problem. I used Militec oil(heated it with a hairdryer) and grease when I set up the gun, and clean with Hoppes 9 and a little RemOil and Militec grease after it's clean.

Regards,
Stojan

I beg to differ.

Walnut, or any other gunstock wood, is not any more likely to crack in below freezing, or even sub-zero temperature, then any other temperature.

A properly air or kiln dried & finished walnut stock is about as inert a material as there is in freezing temperatures.

We fought the revolutionary war, and WWII & Korea in below zero weather with walnut stocked muskets, or M1 Garands & M1 Carbines.

And the Russians didn't have any problems with birch stocked Mossy's in severe winter weather either.

Splitting firewood with an ax in freezing temperature is a whole different deal, because it is still full of sap inside, and frozen solid.

I guess I should have added, the walnut stocks that I paid too much for, I do not shot :-[

However, I was really hoping you could add some more about the ductile brittle transition of 4130... I could only find that one chart on line and I lost my Mark's Handbook years ago. common sense says battle rifles see much colder conditions and is there problems, I don't know that one

You got me.
I have never heard of a gun barrel blowing up because it got too cold.

For that matter, I never had a car door break off the henges in -20 degree weather either. But maybe they do?

As for the chart?
I know next to nothing about impact energy and how it relates to temperature.

But I think a 4140 barrel stays plenty strong way colder then anyone would be able to be out shooting it!

Yes, but would one fire in Florida right now - it's cold here!  :)[/quote]

If it gets down that low here...I'm gone...not gonna stick around long enough to find out.

Cold or hot, mine has been perfect! Most newer firearms are manufactured to withstand extremes. You wouldn't want to go bear hunting with a rifle that can only be fired in 70 degree weather!

I have shot my P3AT and SUB2000 in 5 degree weather last year! They worked ok with no damage! I live in NW Ohio myself.
