It is my opinion that the use of a gun safe is most appropriate if such weapons would otherwise be available to young children. In any other case, I do not agree to their use.
Gun safes are ugly and cumbersome. To use any of them, is to know where they will be placed, such that the flooring will accept the weight.
I much prefer to adequately insure my weapons, and then enjoy viewing them; actually living among them. I can't see the ownership of firearms if that ownership must be tempered by fear and hiding.
