The 10.6×25mmR German Ordnance cartridge, also called the 10.6mm Reichsrevolver, the 10.6mm Service Ordnance, or the 10.55mm German cartridge, is a pistol cartridge designed by the then newly formed German Empire for their first two official service revolvers the M1879 & M1883 Reichsrevolvers.
It is believed to have been influenced by, or developed from the .44 Russian cartridge, which had been developed by the American firearms manufacturer Smith & Wesson for the Armies of Imperial Russia.
