Produced in 1896 until 1938 by Mauser, it was sold to both civilians and military. As a military sidearm, the pistols saw service in various wars, as well as World War I and World War II, and it's now a relic of the Old World.
It has 2 less maximum damage than a Colt 6520, 3 less hexes worth of range, and 5 less rounds in its top-loading feeder. 9mm rounds are also rare and ineffective compared to 10mm rounds. It may have a +20% to-hit because it is "extremely accurate", but that makes little up for its sub-par performance.
