Buying a gun safe is past due. I've been dragging my feet because there is no easy location in my small home. It's on a slab with no basement so it has to be either a bedroom or the garage. At present the garage gets the nod. There is simply no room in the house. Are there any problems I should prepare for in an unheated garage? I'll plan to build a cabinet around it to conceal the safe from service people and others who might wonder why I have such a large safe. The one I am considering is about 48" wide. Plan B would be a much smaller one that would fit in the house and only contain my most valuable firearms. I don't really have an extravagant collection, but do have a few guns that are priceless to me; family heirlooms and a few hard to find items. I'll appreciate your thoughts.
