The weapon should have no ill effects due

 

Firearms have been around much longer than the technology to keep things and people climate controlled has.

 

In general, the gun is less affected by temp swings; the ammo more so, but nothing to lose sleep over.

I'm a native New Englander relocated to the AZ desert for a decade now... I'm quite familiar with both ends of the thermometer. But since you're in Texas, I'll talk to the upper end. What I've noticed is that in hot temps, I need to lube the guns (autoloaders in particular) more often. Conventional lubes tend to migrate due to gravity and evaporate in the hot summer months. As a result, my autoloading pistols get grease (Slide Glide is my choice) on sliding parts like slide rails, and oil on rotating parts like pivot pins. The grease remains in place in extreme temps (measured my glovebox temp at over 140F last summer), but the oil needs to replaced periodically. A weekly check should be sufficient.

Regarding ammo, AZ is a truly dry climate and condensation is a rare problem. I've kept ammo in the car for over a year and it's never failed to go bang. I suppose if you're coastal and you've got ammo in the glovebox, it could develop some condensation after a hot soak when the AC cools the car down, but I would truly be surprise if that compromised the ammo performance in any way. If you want to be absolutely safe, I'd suggest rotating (replacing) your carry rounds on a monthly or bi-monthly basis.

A/C will only dry the air in the car, it removes moisture from the air. That is why it runs in the defrost position, moisture clings to the evaporator and is dripped out on the ground.

 

Keep it cleaned and lubed. It will work if you know how to use it.

However, if you choose to go amphibious with it, you will need to fully brake it down (yeah, the little springs and stuff) and make sure those parts do not lack lubrication, and propper love.

If you choose to own and depend on a firearm/weapon, you had just be learning to be an expert on that particular firearm/weapon. Just sayin............................

Good Question! What ^^^^ gasmitty said (above).

 

The weapon don't care. Reaped movement from cold and warm may require a wipe down more often to remove condensation.
Extreme cold where the weapon is not next to your body may make using a lighter lube a good idea on some hand guns.
Ammo you need to shoot what is in the the weapon now and then and replace it with new rounds from reliable storage no madder what anyway.

 

Since I am not allowed weapons in my place of work I am courious about the affects of repeated exposure to extreme heat and cold on both the weapon and ammo.

Keep it clean and well-lubed. All should be well.

Ammo is self-contained. Though, the exterior surfaces can, over time, develop minor corrosion. But with defensive ammo we're unlikely to be keeping it around forever, particularly inside of a given gun. Rotate the ammo on a reasonably regular basis (something less than 1yr timeframe), and you shouldn't have any problems.

Firearms have metal parts, and not all metal bits in all guns are going to be treated against all environmental conditions equally well. So, just keep your gun clean and free of debris, well-lubed. Occasionally, do a "deep" clean, to get into all the little nooks and crevices, check the springs/bars and other little metal pieces that could, over time, develop little problems here and there. Imagine a gun that's being dunked in salt water frequently, then not cleaned nicely. In time, it'll begin to develop issues. Go after the gun occasionally as though it were that sort of thing, a gun that's been subject to such threats. Treated that way (albeit on a much longer timeframe, given that it's not salt water you're speaking of), it's hard to imagine a given gun's going to give up the ghost with any frequency.

 

I know this is not the question you asked, but I'd be more concerned about someone stealing the gun left in a glove compartment.

 

Try not to leave cast bullets in the gun if it is exposed to extreme heat. The lube may soften or even liquify and contaminate the powder charge. I have known of this happening to 44 special factory loads after being left in a vehicle during the day for about a week. Leaving the windows open 1/4" and the use of a sunshade,will drop interior temps over 100 degrees. Would you want to put your gun in a 200 degree oven? I have "heard" of thin wooden grips cracking on 1911s after extended exposure to high heat. It does get hot down here in GA. I am not picking on polymer guns but, direct exposure to sunlight while in a closed vehicle may cause warpage of the frame in the non-reinforced areas. Some of the polymers used today have good "memory" and will return to their original shape after cool down. 1 of my Glocks developed the "Pig Nose" and has never been exposed to high temps.. Then again, how do you fix the "Pig nose" on a Glock...Heat it up and bend it back..

Just food for thought.

 

They are built for war, hot and cold arent going to hurt them.

 

Well, some of them are. And on such beasts, I'd agree heat/cold won't affect them much, if at all.

Manufacturing and metallurgy standards evolve, and not all makers implement war-grade utility into all parts at all times in all models of guns. And then, designs can either help or hinder certain problems. Like with simple condensation causing corrosion and sticking of parts, if those exposed parts aren't well-protected, -coated or whatever. Some makes/models of guns are known for not having such issues even when heavily used in horrible conditions (ie, the H&K USP line), or Glocks. Some exhibit corrosion issues at much, much earlier times.

Have had a couple of lower-end pistols that showed far greater wear in short periods of time than every other gun I had, yet I've only been shooting less than 25yrs. Doesn't seem right, yet those couple showed distinct signs of wear, despite being treated as well as every other in the stable. Am assuming I either habitually flubbed the maintenance routine on these two pistols (not likely), or the metallurgy and/or surface protections just weren't up to snuff on them. Same shooter, same conditions, same basic maint/cleaning routines, same storage environment.

 

As the others have said, keep it clean and lubed and you should be good to go. If transitioning from cold to heated areas you may encounter condensation on your gun. Wiping it down and keeping it lubed will protect it.

 

You should be fine with any modern firearm

 

I have never pamperd my babys. except when at -50f, to much lube on fireing pin may give problems ??

 

It will be fine.

 

The gun will be fine. Your sides reacting to the extremely cold gun, or in some cases hot, not so much.

 

Get a gun safe for car

 

Yeah, you should definitely do that. I have one of those sub $100 quick access safes cabled to the seat brackets and hidden out of sight. I'm sure that a determined thief could take it, but it may at least slow them down.

 

My G23 is my car gun. Been that way for a decade. She is just as functional and gorgeous as the day we met!

 

As long as it stays dry it will be fine. Like other said keep it cleaned and lubed you will GTG. My issued 870 and later my 11-87 rode for years inside a Crown Vic with no ill effects. Going back even farther my issued GAU-5 (an older AR variant) spent alot of time in a very hot/ humid jungle environment and later a hot dry desert environment with no ill effects. YMMV.

 

The paperwork with my new Bianchi leather holster did say not to leave the holster in a vehicle because of the hot and cold but I wouldn't think it would hurt the gun.

 

I guess that someone would have to look at the true meaning of "MIL-SPEC" "War" guns are built sloppy enough for parts to interchange...

 

I got to tell ya that the heat and cold dose effect you carry weapon. Mine spends 8 hours a day in a cable box safe and when I pull that sucker out when its 130+ in the car and stick it in the holster it tends to burn the love handles a little bit. Other then that I have seen no ill effects of 20 below to 110+.

 

Like others have said, I think the gun would be okay but the holster is another story. I keep my Beretta Nano in the center console in a Desantis Superfly. I removed the outer flap from the Superfly which leaves the strip of velcro exposed. I then put a piece of velcro in the console to keep the holster upright and within easy reach. The heat does a number on the stickiness of the velcro backing so I've had to reglue it a couple of times.

 

Just something to think about.. Police departments leave rifles, shotguns and ammo in the vehicle passenger compartments as well as trunks year round with no ill effects.

Best!
