Unlike a basic cabinet which may have a lock to keep children out, a true gun safe offers far more security. When I was growing up, my father (a skilled but amateur remodeler in Detroit) constructed a secret room in our basement to house his collection. Any potential burglar would have had a hard time finding it. A 500 pound gun safe may yell, "This home has guns," but the chance of a burglar actually moving it, or getting in, is pretty impossible.

My new Springfield uses the "ILS" Integrated Locking System, and a basic cable lock secures my wheel guns. Now that my collection is starting to grow, I need to find a permanent firearm storage unit for them….though they will still come out to play as needed.
