This shotgun is a hammerless, pump action, take-down design with a tubular magazine which holds 5 shells. 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. Stevens also further modified the design when they introduced the streamlined Model 620 in 1927. Under Savage ownership, Model 520 production continued until 1939 when it was replaced by the Model 520A which ended production in 1948. After the war, Stevens was sold to Savage Arms on 1 April 1920 and full production of civilian firearms resumed. 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.
Stevens was sold to New England Westinghouse on and production of civilian firearms was greatly reduced. The Stevens Model 520 was a pump-action shotgun developed by John Browning and originally manufactured by the J Stevens Arms & Tool Company between 19. Stevens Arms Co/Savage Arms Co (1916-1955)
