The Dreyse Model 1907 is a semi-automatic pistol designed by Louis Schmeisser. The gun was named after Nikolaus von Dreyse, the designer of the Dreyse Needle Gun. The Waffenfabrik von Dreyse company was acquired by Rheinische Metallwaren & Maschinenfabrik Sömmerda in 1901, although the Dreyse Model pistols were marketed under the Dreyse name. The same company also manufactured a 6.35 mm pocket version (also named Model 1907). In 1912 the 9 mm Parabellum Dreyse Model 1912 emerged as the gun's successor. Marked as the RM & M Dreyse, it was chambered for 9 mm Parabellum.
