When the supply of M1911 pistols began to run low during World War I, the US Army commissioned a new revolver to augment their supply. The Smith & Wesson Model 1917 was essentially an adaptation of that company’s Second Model .44 Hand Ejector, chambered instead for .45 ACP, employing a shortened cylinder allowing for use of half-moon clips, and a lanyard ring on the butt of the square butt frame. This new revolver also served to replace a range of 1890’0s-era .38 caliber Colt and Smith & Wesson revolvers that had demonstrated inadequate stopping power during the Philippine-American War. The Smith & Wesson M1917 is distinguishable from the Colt M1917 in that the S&W cylinder has a shoulder machined into it to permit rimless .45 ACP cartridges to headspace on the case mouth as with automatic pistols. This double-action revolver was manufactured for Brazil in 1937. The revolver features wooden grips and fixed open sights. Its wood is in fair condition and its metal and bore are in good condition.
