My shotgun is my go to for home defense. The likelihood that I would be awakened from a sound sleep or at least in a drowsy state and then the need to jump into full self defense mode (at my age -I'm 70+) and expect great accuracy with my handgun or even an AR seems like a moot point. Grab the shottie, reactively point and shoot is the conclusion to which I have arrived. The idea of an SBR'd AR however is appealing - either a BO or even my 10.5" (suppressed) 5.56. Hopefully, I will never have to find out. I suspect that within a minute or two of any shots being fired most perps will head for the hills or a hospital ER. Except for the most determined of thieves or those on drugs, the average confrontational gun fight is over rather quickly. My German shepherd and my Malinois might have something to add to an intruders discomfort before I can make my point!!
