With cold/cool weather here concealed carry can be more complicated with more clothes between you and your pistol.
Cold Weather Concealed Carry
Cold Weather Concealed Carry
I carry IWB year-round. If it gets cold enough to need a heavy jacket that interferes with access to my EDC weapon, I will throw a snub-nose revolver with a concealed hammer in my outer jacket pocket. This offers the ability to fire from the pocket in an absolute emergency when there is not time to access the gun in my waistband. I know that this will ruin my jacket if I ever have to do it, but I figure that would be the least of my worries in a situation that required immediate access to a firearm.
