PM M1910

The Pulyemyot Maksima PM1910 (Пулемёт Максима образца 1910 года), or PM M1910, is a heavy machine gun that was used by the Imperial Russian Army during World War I and the Red Army during the Russian Civil War and World War II. Later the gun saw service in the Korean War, the Vietnam War and the 2022 Russian invasion of Ukraine.

History
It was adopted in August 1910 and was derived from Hiram Maxim's Maxim gun, chambered for the standard Russian 7.62×54mmR rifle cartridge. The M1910 was mounted on a wheeled mount with a gun shield.

In 1918–1920, 21,000 new Maxim 1910 machine guns were manufactured in the Soviet Union for the Red Army.

In 1930, a modernized version 1910/30 was adopted by the Red Army. M1910/30 can be equipped with optical sight.

In 1941, the gun was modernized once again.

In May 1942, an order was given to begin the development of a new machine gun to replace the Maxim 1910/30. On May 15, 1943, the SG-43 Goryunov was adopted and since summer 1943 Maxim guns were replaced in Soviet service by the SG-43, which retained the wheeled and shielded carriage. However, production of the Maxim did not end until 1945.

In addition to the main infantry version, there were aircraft-mounted and naval variants. Some were fitted with a tractor radiator cap fitted on top of the water jacket to allow handfuls of snow to be packed in to melt while firing.

After World War II, the Maxim was phased out of service, but was still sent in some quantities to the Korean War and Vietnam War. In 2014 during the war in Donbas, some Maxims in stock were captured by the Pro-Russian separatists while others were taken from storage to be used by the Ukrainian Armed Forces. A number were used by the Ukrainian military during the 2022 Russian invasion of Ukraine due to their reputation for accuracy and reliability.
