Nagant gas-seal Revolver M1895

The Nagant M1895 is a seven-shot, gas-seal revolver designed and produced by Belgian industrialist Léon Nagant for the Russian Empire.

The Nagant M1895 was chambered for a proprietary cartridge, 7.62×38mmR, and features a gas-seal system, in which the cylinder moves forward when the gun is cocked, to close the gap between the cylinder and the barrel, providing a boost to the muzzle velocity of the bullet and allowing the weapon to be suppressed. Its design would inspire the Pieper M1893 carbine[5] and Steyr 1893 revolver.[6]
