Wow, what a thread. When I was a corrections officer, I had a STEN Mk2 under the couch, a Sig P226 in the kitchen, and a Winchester 1300 and Ruger Mini-14 in the bedroom. Just being the good Boy Scout that I am - Be Prepared. Now that I'm in the relatively safe field of being an infantryman, I just have a Glock sititng in my room and a shotgun in the closet. No kids to worry about and anyone else that comes in is a potential target.
Now a word about safes. They are useless for anything but storage. We had a guy decide to start firing a few rounds at a formation today at Ft. Campbell. We have 100 M4s, a few shotguns, pistols, and machineguns and nothing was around to provide defense. Luckily the guy was a shitty shot.
