I was once in the shower and looked out the window to see a guy in the back yard! I jumped out and grabbed what was "handi" -- a Youth 20ga. Pardner, and three shells of buckshot (two in fingers of left hand, shell in chamber, hammer back, gun open).
I watched furtively and quickly found he was real interested in the telephone equipment on the other side of the back fence and was not even looking at the house. Good thing, or he'd have seen a naked guy running through the house with nuttin' but a shotgun and soap suds.
I threw some clothes on, dropped a pistol in my pocket and went out front to talk to the guy ... now in his work truck. He was a 'phone co. employee and hadn't realized anyone was home. He claimed he rang the bell, but I think he just made an assumption on a weekday afternoon.
Did I want more gun? A Garand or a pump shotgun would have been better. Did I feel unarmed? Far from it.
Anyone considering this should start by viewing Clint Smith's demonstration on YouTube. Most of us can't run a s/s that fast. I'll stick with a pump shotgun.
All my best,
