My Great-Grandpa carried the "assault weapon" of his day when he was the neighboring county's sheriff in the early 1930s.
He carried a Winchester Model 1907 in .351 WSL.
Intermediate caliber, semi-automatic, detachable magazine.
He also carried a shotgun, but that was more so he could stop and shoot at birds as the mood struck him.

Big Sister: "Everyone in America is fine with the .30-30, except Mack. He has to shoot that .35 because that extra point zero fives inches will matter on Bigfoot."
