History: The Winchester Repeating Arms Company introduced the model 40 shotgun in 1940 to fill the gap in the semi-auto shotgun market they created when they stopped production of their model 1911 self loading shotgun back in 1928. The model 40 was quickly recognized as a poor design and was discontinued in 1941 with approximately 12,000 pieces manufactured and many of them were recalled by the factory.
