The French military were introduced to the cartridge when the US demonstrated the Pedersen device after the end of World War I in Le Mans and again when John Browning exhibited a carbine in the same caliber in 1920.
Pedersen also designed the Pedersen Device during World War I. This was a sub-firearm intended to allow battlefield conversion of Springfield and M1917 Enfield rifles into semiautomatic rifles firing a pistol-sized cartridge.
