Stevens Model 520/620

The Stevens Model 520 was a pump-action shotgun developed by John Browning and originally manufactured by the J Stevens Arms & Tool Company between 1909 and 1916. Stevens was sold to New England Westinghouse on 28 May 1915 and production of civilian firearms was greatly reduced. The company was renamed the "J Stevens Arms Company" on 1 July 1916 and New England Westinghouse used their manufacturing facility in Chicopee Falls, MA to produce Mosin-Nagant rifles under contract for the Russian Czar during World War I. After the war, Stevens was sold to Savage Arms on 1 April 1920 and full production of civilian firearms resumed. Under Savage ownership, Model 520 production continued until 1939 when it was replaced by the Model 520A which ended production in 1948. Stevens also further modified the design when they introduced the streamlined Model 620 in 1927. The Model 620 was internally similar to the Model 520 and was produced until 1939 when it was replaced by the Model 620A which ended production in 1955. This shotgun is a hammerless, pump action, take-down design with a tubular magazine which holds 5 shells. All models can also be slam fired: the shotgun has no trigger disconnector and shells can be fired one after the other simply by working the slide if the trigger is held down.
