The Langenhan was a German semi-automatic service pistol developed for the German army with which it was in service from 1915 to 1919. The Langenhan was chambered for the 7.65 mm Browning cartridge which it took from an 8-round magazine. The Langenhan had a 105 mm barrel and had an unfortunate tendency of the breech-block being blown out of the slide and back at the firer during operation. Research Langenhan
