Developed late in World War I, the M.P.18 would be one of the earliest practical submachine gun designs, and earned a reputation as a fine weapon for high-speed close-quarters battles like in trenches and built-up areas. Blade front and folding ladder rear sights, with a perforated heat shield around the barrel, the Haenel markings on the magazine well, and "THEODOR BERGMANN ABT.WAFFENBAU SUHL" on the left rear of the receiver. Fitted with a smooth pistol grip stock with forearm grasping grooves, a brown leather sling and a steel buttplate.
