"Fear the man with one gun, he probably knows how to use it"
Yeah? I'm skeptical. Usually they never shoot their one gun and have had the same box of ammo for twenty years.
The only exception I can think of was a couple of guys I know extremely tangentially who teach classes and do kind of big shot body guard work, like really famous people, transport jewels and stuff like that. They do seem like a couple of tough characters and I guess one of the guys mentioned he has a glock and a semi auto AR15, that's it. no 10/22, 870, nothing else. He needs the guns he has to teach classes, which are pistol and carbine related classes, and, I guess, to kill people at work if it comes up. Course I have a gazillion guns and he can shoot rings around me.
Generally though, I am skeptical.
