At the time of his death, John Browning was hard at work (“hard” was the only way he knew how to work) on an over-under shotgun. The only O/Us around in the 1920s were high-dollar guns, and Browning wanted to make a gun priced within the reach of average hunters and shooters. His son, Val, completed the design, which debuted in 1931. Like most John Browning guns, it’s complicated, with lots of parts. It also has a high, ungainly profile, which, according to shotgun theory, doesn’t point as naturally as a trimmer design. And yet, it’s a great gun, easy to shoot well, and it became extremely popular among the very customers Browning hoped would buy it: regular people willing to save up for a good gun. It was made until 1975, then replaced by the simpler, less expensive Japanese-made Citori, which earns an honorable mention spot on this list, as does the Winchester 101, Winchester’s Japanese-made answer to the Citori.
