Cold weather issue

[M4Mike]

I live in northern Pennsylvania and I have recently purchased a new cw9. I have put about 300 rounds through it with no issues until it got cold out. When it gets cold out the gun will not fire or you have to jerk on the trigger. I took the slide off and cooled it down. The pistol worked just fine but when I cooled off the lower it will not fire. I did this multiple times with the same result. Any thoughts?

Looks like you have a couple of options.

1. Sell the gun to someone from the South.

2. Call or email Kahr requesting warranty service and a prepaid shipping label.

I'm sure someone will offer some other suggestions, like a heat gun and thousand foot extension cord, but they may not be practical.

it ain't the weather. u have something wrong with the gun. I would go with Tucson MTB and at least give kahr a call and run it by them and if they need to have it back then insist they pay to send it back.

document what the issues are if it goes back, so they have a place to start looking.

I am assuming u have taken the slide completely down and cleaned and checked out the striker channel. Dry is good in the channel. less lube the better..

How cool are we talking here M4? Freezing?

My thinking is a carry gun should never get that cold, and if deployed even in sub arctic temps it would run and keep running plenty long enough till your out of bullets for a long time.

If its left in your glove box unoccupied it could get cold enough for any lube or grease to freeze up and literally gum up the works.

When it's cold as Jocko so eloquently stated little or no lube is best.

Too cold? No such thing as too cold. Northern deer hunters including those from the great State of PA have never heard of such an issue with firearms. I understand this is not your hunting weapon, but I can't imagine any of the hundreds of thousands of guns out here in the northern cold having mechanical problems because of cold. Deer hunting and the gun industry would be a total wreck and make our new/old President really smile. Really?...too cold?

Mike, I'd get dig a bit more for the real problem, as Jocko suggests. Sir, with all due respect, something is going on but it tain't the cold. Could be the lube, could be the prep, could be alot of other things...but not the cold.

Here is the response I got from Kahr about the cold weather. I wouldn’t consider 35 degrees “extreme cold”. Good afternoon. This can at times be an issue with the polymer frame contracting in theextreme cold. As this is designed to be a concealed carry firearm we wouldnormally expect some form of on body or very close to body carry the bodytemperature would avoid this contraction and thus any such issues. Have a good day from Kahr.

After reading the Kahr reply I now have another reason why I'm glad I own 2 Steel Kahrs'.

[hardluk1]

I am a dumby that will shoot year round despite the cold and have shot my kahrs when in the high teens with no problems also so used the same lubes at 5 to 10* below zero with no problems. I don't use old school lubes , only synthetics. I still can't see even some 40 year old rem oil causeing problems even at 20*. Got be a mechanical problem.

Never take the manufacturers first response to be the final word.

[M4Mike]

I responded to there e-mail and this was there response.......
Good morning. Our firearms are polymer only and as such are more sensitive to temperature. As this is designed to be a concealed carry firearm and small enough for on body carry the idea is that the firearm would be kept warm by the body carrying it. This would generally mean the firearm would be in a relatively constant temp well above 35. Have a good day from Kahr.

more than likely

that comment came from the janitor at kahr. as that is pure bull sh!t. Glock would be out of business if this was even the slightest bit true. If u wana bury ur kahr in the snow for a week. to prove a point, then IMO, u need some special attention, NOT THE GUN. It seems we always try to puch the envelope on everything. I have no doubt that proper lubricants play a big part in anything working.

I can remember years back that My harley just used 20-50 normaql oil as that was all there was. In the dead of a good winter, that bike would hardly turn over due tothe lubricant being so so thick. i now run the modern synthetics in my Harley and althought it doesn't crank over like 80- degree days, it does crank over and with modern fuel injuection ALSO STARTS.
Put thick grease on ur gun in the winter and don't expect it to get thinner, it willget thicker. I would blame the lubricants before I would blame any gun. Just sayin.

I left my G-Lock in a bucket of snow last year to check it's reliabilty.

I left my CW9 out in the cold for 2 days at 32 degrees max, probably lower temps.

Both the G-Lock and Kahr shot fine and yes I'm special anyway.

Really just bored with way too much idle time on my hands.

We do have some snow now, maybe I could fill a bucket up with snow and put the Kahr .........

[mr surveyor]

I would consider flushing out the firing pin/striker channel real good with break cleaner or other pressurized non-lubing gun solvent.... and NOT adding lube to that area. I can imagine light strikes from cold induced gummed up striker.

just a thought

I have sent Kahr another request for a repair order number.

[kuchman]

I agree with most of the others; the gun is the issue. I shot my CW9 in 20 degree weather the other day with no issues. It was on the tailgate of the pickup for 20 minutes before I got my targets up. Shot 50 rounds with no hiccup. I assume you already tried firing the gun dry or with a good synthetic lube.
Sounds like you got a real idiot on the phone to give you "the fix".
Keep trying!!!!
Good Luck..:33:
