The Winchester M1897 shotgun was designed as an improvment from the Winchester M1893 created by John Moses Browning. The shotgun was popular and saw extensive use in both World Wars.
Kanta's M1897 is likely the Riot model as it lacks the bayonet lug and heat shield of the Trench model while maintaining the shortened barrel.
