M1917 revolver
The M1917 revolvers were six-shot, .45 ACP, large frame double action revolvers adopted by the United States Military in 1917, to supplement the standard M1911 pistol during World War I. There were two variations of the M1917, one made by Colt and the other by Smith & Wesson. They used moon clips to hold the cartridges in position, to facilitate reloading, and to aid in extraction, since revolvers had been designed to eject rimmed cartridges and .45 ACP rounds were rimless for use with the magazine-fed M1911. After World War I, they gained a strong following among civilian shooters. A commercial rimmed cartridge, the .45 Auto Rim, was also developed, so M1917 revolvers could eject cartridge cases without using moon-clips.
During World War I, many U.S. civilian arms companies including Colt and Remington were producing M1911 pistols under contract for the U.S. Army, but even with the additional production there was a shortage of sidearms to issue. The interim solution was to ask Colt and Smith & Wesson, the two major American producers of revolvers at the time, to adapt their heavy-frame civilian revolvers to the standard .45 ACP pistol cartridge. Both companies' revolvers utilized half-moon clips to extract the rimless .45 ACP cartridges. Daniel B. Wesson's son Joseph Wesson invented and patented the half-moon clip, which was assigned to Smith & Wesson, but at the request of the Army allowed Colt to also use the design free of charge in their own version of the M1917 revolver.
The Smith & Wesson Model 1917 is essentially an adaptation of the company's .44 Hand Ejector 2nd Model chambered instead in .45 ACP and employing a shortened cylinder and a lanyard ring on the butt of its frame.
The S&W M1917 differs 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 they do in automatics). The S&W M1917 can thus be used without half-moon clips, though empty .45 ACP cases, being rimless, must be poked out manually through the cylinder face as the extractor star cannot engage them.
Colt had previously produced a version of their .45 Colt caliber New Service model, designated the M1909, to replace their .38 Long Colt caliber M1892 revolvers that had demonstrated inadequate stopping power during the Philippine–American War. The Colt M1917 revolver was essentially the same as the M1909, but with a cylinder bored to take the .45 ACP cartridge and the half-moon clips to hold the rimless cartridges in position. In early Colt production revolvers, attempting to fire the .45 ACP without the half-moon clips was unreliable at best, as the cartridge could slip forward into the cylinder and away from the firing pin.[citation needed] Later production Colt M1917 revolvers had headspacing machined into the cylinder chambers, just as the Smith & Wesson M1917 revolvers had from the start. Newer production Colts could be fired without the half-moon clips, but the empty cartridge cases had to be ejected with a device such as a cleaning rod or pencil, as the cylinder extractor and ejector would pass over the edge of the rimless cartridges. Firearms developer and writer Elmer Keith considered the Colt model "rough finished" and generally not as well made as the Smith and Wesson.
From 1917 to 1919, Colt and Smith & Wesson produced 151,700 and 153,300 M1917s in total (respectively) under contract with the War Department for use by the American Expeditionary Force. The revolver saw prolific use by the "Doughboys" during World War I, with nearly two-thirds as many M1917s being issued and produced during the war as M1911s were.
The military service of the M1917 did not end with the First World War. In November of 1940, the Army Ordnance Corps recorded a total of 96,530 Colt and 91,590 S&W M1917s still in reserve. After being parkerized and refurbished, most of the revolvers were re-issued to stateside security forces and military policemen, but 20,993 of them were issued overseas to "specialty troops such as tankers and artillery personnel" throughout the course of U.S. involvement in World War II. During the Korean War they were again issued to support troops. The M1917s were even used by members of the "tunnel rats" during the Vietnam War. Overall, the two variants of the M1917 enjoyed over fifty years of service in the U.S. armed forces.
The British Army adopted it during World War I, and the Home Guard and the Royal Navy used it during the Second World War.
