Lineage
History
Developed in the early 1930s by SACM (Société Alsacienne de Construction Mécanique) alongside the MAS 1935 pistol to replace the 8mm Lebel revolver cartridge in French military service. It served as the standard French military pistol cartridge through World War II (under German occupation, German forces also used captured MAS pistols) and into the postwar period, until France transitioned to the 9mm Parabellum with the MAC Mle 1950. The cartridge was officially retired by the French military in the 1970s.
