Widely considered a genius and inarguably the most famous gun maker in the history of the universe, perhaps Browning's most enduring legacy is the short recoil design behind the 1911 handgun, which remains the pre-eminent operating system in today's semi-auto handguns, nearly a century after it was first introduced.
Not a handgun fan? OK, then there's his other creations, like the Winchester Model 1886 lever action rifle, Model 1887 lever action repeating shotgun, Model 1897 pump action shotgun and Models 1894 and 1895 lever action repeating rifles.
For good measure throw in the Colt Model 1895 "Peacemaker" machine gun and Model 1817 .30 cal. water-cooled machine gun.
