The Savage-Stevens model 520 Shotgun was designed by the famous American gunmaker John Browning in 1903. Stevens Arms and Tool Co purchased his patent in 1904 and soon¬†produced a new sporting gun, designated as the¬†Stevens model 520. It was a successful design, one of the first ‚Äúhammerless‚ÄĚ (internal hammer) pump shotguns on the market. In 1917 Stevens Co developed a ‚Äútrench gun‚ÄĚ version for the¬†US Expeditionary forces in Europe, but it came too late to see¬†any action¬†in WW1. The police version of the basic model however, known as the¬†Stevens model 520 riot gun, enjoyed steady sales in US.
In 1920 Stevens was bought by Savage. Since that time and until the cessation of manufacture in the mid-1930’s, this gun was offered as the¬†Savage-Stevens model 520 shotgun. By the start of WW2 Savage still possessed significant stocks of the Model 520 in its warehouses. Those were bought by the¬†US government and issued to the¬†military.
Due to¬†a lack of spare parts, the¬†Model 520 Trench gun was declared obsolete and withdrawn from service and put into storage in 1943. However, with the start of the¬†Vietnam war, the¬†remaining shotguns were again recalled into service and issued to troops in SE Asia, notably to Military Police. Military issue guns of WW2 era often bore the¬†designation ‚Äúmod.520-30‚ÄĚ and ‚ÄúUS‚ÄĚ on the receiver.
This¬†weapon is a manually operated, slide (pump) action shotgun. It features sturdy construction with an all-steel receiver. The bolt is locked by a tilting lock which engages a cut in the roof of the receiver. Ammunition is fed from an underbarrel tubular magazine. Trigger and hammer unit¬†are mounted on the removable trigger plate, made integral with the trigger guard.
Early (pre-Savage) models featured a manual safety inside the trigger guard. The¬†Savage-Stevens guns had the safety¬†on the tang of the receiver. All Model 520 shotguns also featured an easy ‚Äėtake-down‚Äô (dissasemble)¬†design.
Savage-Stevens model 520 Riot guns were equipped with 20-inch cylinder bore barrels. The trench guns were similar but also featured a ventilated steel handguard and a bayonet mount.
