1917 Army Smith Wesson DA 45

The Smith & Wesson Model 1917 is a legendary U.S. military revolver created during World War I when the Army needed more sidearms faster than the Colt 1911 could be produced.

What made it revolutionary was that it fired the rimless .45 ACP cartridge using ingenious half-moon clips, an invention that later inspired modern speed loaders.

Built on the large and powerful N-frame, the Model 1917 served in:

• World War I

• World War II

• Korea and later secondary military roles

Collectors love it for its:

• “U.S. Property” markings

• Lanyard ring

• 5½-inch barrel

• Smooth walnut grips

• Strong wartime history

Brazilian contract versions from 1937 are especially collectible today. Many enthusiasts consider the Model 1917 the ancestor of famous later Smith & Wesson revolvers like the Model 27 and Model 29.

The Smith & Wesson Model 1917 was primarily chambered in .45 ACP. It was developed during World War I to use the same ammunition as the Colt M1911 when the Army needed more sidearms.

Key details:

• Caliber: .45 ACP

• Capacity: 6 rounds

• Usually loaded with half-moon clips

• Can also fire .45 Auto Rim ammunition in many examples

Most original military S&W 1917 revolvers had a 5½-inch barrel and were issued in both World Wars.
