(1) The front sight of the Luger is a simple inverted V blade that corresponds to an open V rear sight. At ranges over 50 yards, the Luger was one of the more accurate handguns of the early 20th century.  (2) Once the magazine is inserted into the handgrip, the operator chambers the first cartridge by pulling the toggle joint up and to the rear, then releasing it.  (3) The 4-inch barrel—with six right-hand-twist grooves—gives the Luger a muzzle velocity of 1,274 feet per second. (The muzzle velocity of the Browning M1911 pistol, the standard American side arm in the world wars, is 825 feet per second.)  (4) The box magazine holds eight rounds of 9mm ammunition.
