...for society chaos, unexpected invasion, etc. etc........I have chosen...after thinking of several possibilities...the M1...funny because a few years back, I may have thought it too old-fashioned..until I bought & shot one..I was wrong...it has points that others lack...I enjoy shooting it(regarding it as a faithful companion piece)...that means I want to practice with it...it is a stable longarm, it fires a very substantial cartridge, the gun has a history of reliability, even when dirty or in extreme weather(we don't have a lot of extreme weather in Arizona & I regard letting a gun get dirty a sin)...it has superb iron sights & trigger...the reloading system is quick, easy and reliable(no magazine springs to get out of whack at a bad time...topping off is a bunch of crap, who the heck tops off a clip or magazine when in a fight when a full clip or mag is at hand)...even though a 1930's design..still a terrific rifle and my #1 choice!(a riot gun and a short 'longarm' would be nice to augment such a rifle..but I am giving my primary longarm choice on this thread)...
