I like the idea very much, especially for keeping guns away from burglars. Nonetheless, I think one of their goals -- to keep guns readily accessible, but hidden from children -- is probably a mistake. If you ever retrieve a gun from one of these hidden compartments in the presence of small children, they will notice it, and will, in pretty short order, figure out how to get that compartment open. Never underestimate the intelligence of your children; they may be smaller than you, but they probably have as much native intelligence as you do. (Where do you think they got it?)
I keep thinking of a memorable Dennis the Menace cartoon, where in the first panel, Dennis says to a friend of his mother, "Are you the one with the dead hair?" In the next panel, we see Dennis mother insisting to her upset friend, "I said tinted not dyed." Those little rascals hear and see everything you do.
