The Browning Double Automatic was the creation of John Browning's son Val. It's a two-shot, recoil-operated semi-auto. Some would call it the answer to a question no one asked, but those of us who own Double Autos (or in my case, have owned) can tell you that they are light, lively upland guns. Double Autos came in a standard steel-receiver model, a light Twelvette at under 7 pounds, and a really light Twentyweight that scaled around 6 pounds in 12 gauge. The receivers came in different colors—red, green, etc.—and they were made from 1955 to 1971.
