When the Germans came to Belgium without an invitation in 1940, numerous handgun models were in standard production. Of those, the new management would supply over 400,000 Model 1922s to send back to Germany – more than any other design. Dubbed the Pistole 641b (with the letter for “Belgian”) in the .380 version and Pistole 626b for the .32 ACP, other than P-38s and Lugers, the FN 1922 was the most common handgun in German service in World War II, outnumbering Walther PP/PPKs by a more than 2-to-1 margin.
