Our Assessment: The Colt Model 1917 revolver was manufactured during World War I to supplement the shortage of the Model 1911 semi-automatic pistols. Chambered for the .45 ACP cartridge using half or full-moon clips, these revolvers were reliable sidearms widely appreciated for their power, accuracy, and robust design. This revolver, bearing crisp U.S. military inspection marks—including a notable eagle’s head over "S/6" marking on the left side of the topstrap—offers significant historical interest and collectibility.

This particular example is in very good condition, retaining approximately 90% of its original blue finish, complemented by smooth walnut grips showing honest wear consistent with military use. With a strong, clean bore rating 9/10, it remains an excellent candidate for collectors, military firearm enthusiasts, and shooters alike.

If you’re seeking a classic piece of American military firearms history, this Colt 1917 is a fine representative example deserving a place in your collection.
