Now aware of what I wasn't aware of earlier regarding my gun "accumulation" habits, I would advise finding a safe that you assume fills your needs, get the best price possible, then......................................BUY TWO OF THEM! Make'em give you a better deal for two (delivery, installation, etc.). Don't even think you're gonna' have enough room for not only your guns, important papers, wifes valuables, etc., etc. TR is right, buy big or buy multiple (I prefer multiple) but buy more than you think you need. Just my $.02.
