With its introduction during the interwar years, the Model 1922/Mle 1922 inevitably went to war during World War 2. It was adopted by several European powers (for military and police use) in the time leading up to war and these included Holland, Greece, Romania, France, Denmark and Finland. After Belgium fell to the German invasion, FN factories continued output of the Model 1922 though this time for their German overseers. These production models were applicably stamped with German markings to indicate their fate and were introduced in 1940 under the designation of Pistole 626(b) - the "b" signifying their Belgian origins, common practice for the German Army inventory concerning captured weapons. The Pistole 626(b) was largely issued to Luftwaffe personnel as a standard sidearm.
The Model 1922 saw service through the end of the war in 1945 and after. It was further issued to West German troops following the division of Germany in the post-war world. Several attempts were made in the 1950s by the Browning Arms Company (established to market John Browning's military-minded designs to civilians) to bring the Model 1922 to a broader audience. This created the Browning Model 1955 and Browning Model 1971 designations within time.
