I think it's an excellent idea, if you can do it safely ... with only my wife and myself to worry about, I keep a gun in my nightstand, a second in the cabinet over the toilet (don't want to be caught with my pants down, so to speak, and a third in the room we use in the back of the house as an office ... I also always have a gun either in my pocket or alongside me, if I'm sitting reading or boob-tubing ... I work on the old theory that it's better to have a gun (nearby) and not need it than to have a gun and not have it (closer than the safe) ...
