The 1907 Dreyse is an early automatic pistol whose design is attributed to Louis Schmeisser. It saw fairly extensive use by the German military during World War I, and was also used by various German police organizations into the early 1930s. Overall, nearly a quarter million were manufactured.
It is a simple blowback action chambered for .32 ACP (7.65mm Browning), and not particularly comfortable. It has an awkward grip angle, awkwardly-short distance from grip to trigger, and top-heavy balance.
