I live in Wyoming and routinely use a second gun-belt in order to carry openly in cold weather. It's a leather holster attached to an easily removeable belt and sits low on my right hip. It has actually turned out to be quite a hassle for one reason; it's difficult to get in and out of my truck. When I'm in the truck I have to remove the pistol from the holster and put it between the seats or in my console underneath the dash. Otherwise the barrel is pointed in an unsafe direction (i.e. the vehicle in front of me.) Then I've got to contort my body in order to get the pistol back into the holster before I exit the vehicle.
It certainly is not elegant but allows me to carry openly whilst wearing a winter coat.
