The S&W Model 1917 was produced alongside the Colt Model 1917 to address WWI shortages of the M1911 pistol. Chambered in .45 ACP using half-moon clips, it fed from standard US military pistol cartridges in a revolver platform. S&W's contribution totaled about 163,000 revolvers. Brazilian military and police purchased large quantities post-war, and the Model 1917 saw continued US use through WWII. It was a robust, reliable solution to a genuine wartime emergency.
