my friend has a one story home. the master bedroom has a walk in closet which doubles as a safe room. smaller hardware is distributed somewhat evenly, while long hardware is kept in the garage with the exception of the semi auto SG with extension which is in the safe room. he has also sprinkled a few mag lights around, including some 3 C cell LED maglites, which seem very handy (for example, one is close by the front door).
