Manufactured between 1912-1915, with a limited amount of surviving examples left today. Designed by Louis Schmeisser, better known for his design of the Bergmann machine gun, the Dreyse Model 1910 is a blowback operated semi-automatic pistol chambered in 9x19mm, built with intent for use by the German military and police. It shares some visual and operational similarities to the more common smaller Dreyse Model 1907 pistol chambered in 7.65mm auto that preceded it, although it charges differently. For chambering of the first round, the charging handle is operated by lifting upwards, gripping the serrations at the rear prior to pulling backwards, then pushing forward against spring pressure before closing it back downwards where it clicks into place ready for firing in semi-automatic. Matching full and partial serial numbers marked on the frame, receiver, bolt, charging handle, various components, top lip of the base of the magazine, and faintly handwritten underneath the grips. "Crown/N" German commercial proofs on the left of the frame, barrel housing, and charging assembly. "Rheinische Metallwaaren-& Maschirenfabrik/AET. SOMMERDA." manufacturer markings on the left of the receiver and "DREYSE" on the right above the ejection port.
