Just a few observations about carry in cold weather:
1) Coats with drawstrings can get interfere with accessing or reholstering a handgun, to the point of being dangerous.
2) I try to have no more than one layer of clothing over my gun. Winter makes that harder for me to do.
3) If you wear gloves, make sure they do not keep you from accessing and using your firearm. That limits me to something thin like cotton work gloves. If it's cold/wet enough I supplement them with disposable hand warmers in my coat pockets.
My methods work best for me, but we all have to problem solve these matters in our own way.
