I'm thinking that people who buy AR-15s and such are wanting to kill the perpetrators before they get to into the house. I suppose that in the forthcoming food riots, defenders will need to hit moving targets before those targets let loose with molotov cocktails, bricks and such.
All depends where you live I suppose. In a city, You are most likely going to be defending against anything that comes through your door.
The shot gun will not only stop the perp in his tracks, but deposit him back outside the door, where he won’t be bleeding all over your rug.
When leaving your city house/ apartment, You’d probably want something concealed. People walking around the streets carrying long arms is a little difficult to picture, even in tough times.
Carrying around long arms would be more common in rural areas, Where you can watch for those trying to crash your front gate, or sneak up from surrounding property.
I doubt you’ll see much of that though. matial law would be quickly established, and road blocks would be set up to prevent escapee from leaving the cities in hopes of finding food in the country, which of course there isn’t any.
City people have a unrealistic image in their heads of what is in the rural country side. Farmers with fields full of nice veggies, LoL! Only in some southern states.
grazing on green wheat and oats would loose it’s appeal real fast.
