Here's my first thought. Let me know if I'm an idiot. Buy some new underwear/socks. Take your old stuff, rub it in something to "discolor" it. Lay the gun in the back of your closet or wherever with the "dirty" underwear on it. The idea is no one's gonna look under THAT. I liked the idea of putting it somewhere a thief won't look.
