Ah Texans and Californians, things aren't always what they seem. I only recently moved to Texas (though I did live here in the late 70's through most of the 80's, I am a geologist after all). I've done quite a bit of hunting in sub-zero weather, in fact I love cold weather, enough so that winter hunting and winter camping trips were the norm around our house. I'm cold-blooded enough (must be my German/Norwegian ancestory) that I'm perfectly comfortable using a 20 to 30 degree rated sleeping bag in -5 degree temperatures. It's excessive heat/humidity (like we have here in Houston summers) that I find tough to take!
The only problem I found using my .410 hammer gun in the cold was that the darn trigger guard was scaled to the size of the gun, it looked nice but it's too small for my gloved finger, even wearing nothing but a glove liner on that hand.
