In the event of a drawn out time frame of civil disorder where you reside in a large urban city and large groups run rampant, which would be a better option, a semi auto shotgun(re. Benelli M2, Remington, Mossberg) or a semi auto rifle(Ruger Ranch). My concern is not just home protection but where you might have to attempt to leave your residence and make your way out of the city. Additionally large capacity weapons(shotguns or rifles with a capacity greater than five rounds) or AR's of any kind are not a legal option. Handguns are already covered. Thanks!
