PM M1910

The PM M1910 (Пулемёт Максима на станке Соколова, Pulemyot Maxima na stanke Sokolova or "Maxim's machine gun model 1910 on Sokolov's mount") was a heavy machine gun used by the Imperial Russian Army during World War I and the Red Army during World War II. It was adopted in 1910 and was derived from Hiram Maxim's Maxim gun, chambered for the standard Russian 7.62x54mmR rifle cartridge. The M1910 was mounted on a wheeled mount with a gun shield and was replaced in Soviet service by the SG-43 Goryunov which retained the wheeled and shielded carriage, starting in 1943. In addition to the main infantry version, there were aircraft mounted (PV-1) and naval variants.
