The S1897 is modeled after the Winchester Model 1897 "Trench Gun," designed by John Moses Browning. It was standard issue to the US Army, Navy, and Marines through the Philippine-American War all the way through the Gulf War. 1,024,700 have been produced during their service era. The gun is typically chambered for 12 and 16 gauge, though in the game, it's chambered solely for 12. The gun is largely used as part of police and special forces equipment due to its ability to quickly clear tight areas and its effectiveness in close combat. The S1897 excels in clearing houses with quick and easy use. Caution is to be taken however, It is essential that a player lands their first shot on their target while clearing a house, as missing one shot can easily spell out your death due to the pump action. This shotgun is a firm reminder that in real life, shotguns tend to shoot farther than most people estimate them to. Do not be afraid to take shots at people at a decent range away, especially while utilizing a choke.
