Built in 1918 for the U.S. Army, this Colt Model 1917 service revolver represents a key sidearm of America’s World War I arsenal. Chambered in .45 ACP and finished in dull military blue, it combines Colt’s double-action reliability with the stopping power demanded on the Western Front.

This revolver is an authentic U.S. Army “Model of 1917” variant, verified by the inspector stamp and “UNITED STATES PROPERTY” roll mark on the frame. These markings confirm government acceptance and add military provenance that collectors seek.
The 5.5-inch carbon-steel barrel balances muzzle weight and holster carry, while fixed iron sights—half-moon blade front and squared-notch rear—mirror the original wartime configuration. Smooth walnut grip panels provide period-correct handling and complete the revolver’s utilitarian look.
Chambered for .45 ACP, the Model 1917 uses full-moon clips to extract rimless cartridges, a practical solution devised for war-time logistics. The six-shot cylinder, carbon-steel frame, and external hammer allow both double-action and single-action fire, giving soldiers rapid or precise options in the field.
Surviving examples from 1918 remain desirable for their combination of combat heritage, robust build, and continued shootability. This specimen retains its original dull military blue/phosphate finish, displays honest service wear, and offers a tangible link to the American Expeditionary Forces of the Great War.
