Old Betsy was a famous musket, a gun needs a name. So when Joe Biden told people in 2014 that all you needed for home defense was a double 12 gauge and you just needed to fire a couple rounds off the balcony to scare off those 8 guys about to invade your castle, I bought one.
Mine is the double 12, J2000, with exposed hammers, 18 inch barrels. I just call it, "old Joe". If I ever use it in a home invasion, I will just claim the old Joe defense. Official acts and statements of a President are said to be US policy, so, shooting over the head of strangers in your yard must be Government policy.
Old Ronin just does not have much pzazz. Old Joe sounds more American ninja.
