"If a man can have only one gun, it should be a shotgun." -- By I have no idea.
NOT ENDORSED, but interesting from a fudd perspective.
See TDF 43/44 for a discussion of .410 shotguns.
Certainly, using a shotgun for home defense has its downsides, too: Its recoil is significant, most are slow to reload and they are neither lightweight nor easily concealed. Still, if I had to pick one gun for home defense, hunting, survival and sport, I’m going with a 12-gauge shotgun. In trained hands, you’re unlikely to miss close-range targets and whatever is hit with is unlikely to hit back.
