History
Introduced in 1905 for the Winchester Model 1907, a blowback semi-automatic rifle considered advanced for its time. France purchased large numbers during WWI for pilots, cavalry, and vehicle crews who needed a compact semi-automatic weapon. Russia also purchased the Model 1907. The cartridge and rifle were commercially available until the 1950s; factory ammunition production has ended. Original Model 1907 rifles in good condition are collector items.
