"I used to believe the shotgun was a good idea. Then the 1992 LA Riots came along. For three to five days folks were pretty much on their own. Businesses were being torched over a wide area. Finally the Korean business men went on the roof of their businesses with rifles and it stopped. If you don't have access to a long range rifle, it leaves you open to some sucker that has looted an arms store, and wants what you have, or to destroy what you have. Can't take a shotgun to that type of a fight."
Very good point - Add a rifle to the shotgun and handgun mix. Keep plenty of ammo at hand. Don't live in LA

"Can't take a shotgun to that type of a fight."
Sure you can! With a 20 in. Barrel and ghost ring sights, as on my Mossberg 590, you can hit consistently at 75 to 100 yds. with practice.
