I have been reading everything I can find about a home defense arsenal. I cannot find any justification for choosing a shotgun over an AR except for cost. The shotgun is slow to reload, carries a limited amount of ammo, the ammo for it is large and heavy, the tube magazine is susceptible to damage rendering the shotgun useless.
Well the only justification I can see is for bears but those are very scarce here. Or for three gun.
Any substantial arguments for a shotgun being a necessity?
edit to add.
Actually I said that wrong. Its not about choosing a shotgun over an AR. What realistically does a shotgun bring to the table that the AR doesn't cover. Or an AR combo of a 5.56 and a .308.
