POTD: The Improved Model 520 – The Stevens Model 620 Trench Gun

Welcome to today’s Photo of the Day! The Stevens Model 620 was an improved pump-action shotgun introduced in 1927. As an upgrade to the original M520 design by John Browning, the M620 sported a more rounded receiver and other enhancements. Offered in 12, 16, and 20 gauge with barrel lengths from 26 to 32 inches, it was a popular general-purpose scattergun. When World War II hit, Stevens produced trench gun versions of the M620 with 20-inch barrels, heat shields, and bayonet lugs for military use. Many found their way into guard and training roles.

“Manufactured on contract, the Stevens 620 was used by the U.S. Army and Marine Corps from World War II up to Vietnam. A single brass bead sight is installed on the bayonet lug, with a six-hole heat shield, cylinder choke, the three line Chicopee Falls address on the right side of the barrel ahead of the “P/flaming bomb” stamps and the gauge and 2 3/4 inch chamber markings on the left. The “P” and bomb are repeated on the left side of the receiver, with “MODEL 620” and “U.S” further to the back, and the serial number and “U/S” on the underside ahead of the trigger guard. Fitted with a smooth round forearm and pistol grip stock, the latter fitted with a sling swivel and a serrated buttplate, with a 13 3/4 inch length of pull.”
