Originally developed with an eye for arming the people of Southeast Asia against the Communists, the United States Army and Marine Corps both took an interest in the 77E as a replacement for their aging stocks of WWI and WWII vintage trench and riot guns. The 77E became very popular as an "anti-ambush" gun in the jungles, as it was capable of delivering immediate and vicious fire at close ranges. While one of the signature weapons of the Vietnam War, relatively few can be found on the American market today in any condition. Single nickel bead sight, an improved modified choke and a 2 3/4 inch chamber. The frame is marked "US" on the right side, with "P" on the upper right side and on the breech of the barrel and "APP-952" added to the frame below the serial number.
