Our Assessment: With America's entry into WWI, it was found that Colt could not produce enough Model 1911 pistols for the U.S. Army. Some .38 revolvers were distributed to rear echelon troops, guard, and the Navy, but the Army also wanted some commercial revolver production to be used for a revolver capable of using the same ammunition as the 1911 semi-auto. Both Smith & Wesson Hand Ejector and Colt New Service revolvers chambered for .45 ACP were approved as substitute standard and designated the Model 1917. Colt's M1917 was built on the same large frame as the Colt New Service revolver, making for a very rugged service revolver. There were many still in inventory when the United States entered WWII and, for much the same reasons, they were once again pulled from inventory and issued out as a substitute standard. Most of those which were issued during WWII were arsenal refurbished and given a parkerized finish.

This example has retained its original blue finish and is a neat example of a WWI-era Model 1917. The revolver shows wear consistent with its age, retaining a strong bore and great mechanics. It looks great with its new Altamont smooth wood grips. This revolver would make a nice addition to a U.S. Military sidearm collection and should still make for a fun shooter. Please see our photos and good luck!
