There is indeed a replica of the mauser pistol, that is, the German Mao Se M 1932 pistol, the world's first military automatic pistol, which was widely used in World War II. This kind of gun was regarded as one of the main guns during the War of Resistance against Japanese Aggression period in China, and China people also gave it various names, such as "Twenty Guns Mao Se", "Box Gun", "Twenty Guns Self-Initiated" and "Speed Machine".
Its biggest feature is that it can be loaded automatically and fired repeatedly, so it is also called submachine gun. The effective range is longer than that of a common pistol, and it can kill the target reliably within a distance of 100m, with an initial velocity of 440m/s.
