The Schwarzlose Model 1898 was a semi-automatic pistol invented by Prussian firearm designer Andreas Wilhelm Schwarzlose. It was chambered for cartridges such as the 7.65x25mm Borchardt and 7.63x25mm Mauser.
The Schwarzlose design was advanced for its time, but not widely adopted. Small lots were sold to the Boers during the Boer War. Another lot was sold to members of the Russian Social-Democratic Party who were plotting insurrection, but were confiscated at the Russian border and issued to the Imperial Russian Frontier Guards.
