SD40VE in Minn. Cold?

[Sunkist]

I bought a SD40VE yesterday and cleaned and lubed it last night and was at the range today. I love it. The trigger is not much different from dozens of DA revolvers and I got into 3" groups at 12 yards quickly. The groups opened when I started to increase the speed but mine always do. 70 rounds fired today.

My question is about reliability in sub zero temps. This is my first poly gun so I'm new to the game. My Sigs, my 4006 and my CZ 75's function as well as my frozen fingers will allow. What about the SD40 VE?
My main concern is the frame.

Graphite was always the preferred lubricant for extreme cold temps when I was a kid. I expect that it still works fine. There may be modern lubes that will work but I'm afraid that I'm not up on them in extreme cold temps. Any local gunsmith ought to be able to recommend a proper lube. I'm certain a forum member from the deep freeze zone will weigh in and make a recommendation.

Best Regards,

I have shot 4 magazines (52 rounds) in Northern Wisconsin near Duluth/Superior in sub zero temperatures (-25), then reloaded and did it again on multiple occasions over the past 2 winters with no adverse effects on my SD9VE. Maybe if you used the grip as a hammer as in self defense,it possibly would crack/shatter?
