Smith & Wesson Model 547 9mm Luger K-Frame Revolver, 4-inch Pinned Heavy Barrel, Blued (1981)
Notable for its scarce production and innovative engineering, this Smith & Wesson Model 547 is a 9mm Luger K-frame revolver built in 1981 with a 4-inch pinned heavy barrel and fixed sights. It uses S&W's patented moon-clip-less extractor system rollmarked on the barrel with U.S. Patent No. 4,127,955, eliminating the need for moon clips with rimless 9x19mm. This early-production, blued carbon-steel example features checkered walnut Magna stocks, a smooth-faced color casehardened trigger, and a semi-bobbed color casehardened hammer.

The Model 547 stands out for its purpose-built 9mm Luger system. Its cylinder and extractor employ S&W's patented, moon-clip-less design, allowing reliable extraction of rimless cartridges without clips. The distinct extractor-leaf apertures are visible when the cylinder is opened, and the barrel carries the U.S. Patent No. 4,127,955 rollmark.
Configuration is classic and duty-ready: a 4-inch heavy profile barrel that is pinned, fixed sights with a serrated ramp front and a square-notch rear integral to the topstrap, and a DA/SA action. The revolver is finished in a rich blued carbon steel.
Controls and trim include a smooth-faced, color casehardened trigger and a semi-bobbed color casehardened hammer. The K-frame, square-butt grip frame wears checkered walnut Magna stocks with S&W medallions, and the six-shot cylinder is chambered for 9mm Luger.
Production of the Model 547 ran for a short period circa 1980–1985, making examples comparatively scarce. This 1981 revolver is an early-production piece with its pinned barrel, and matching serials are observed on the butt and yoke. Made in the USA, it represents a distinctive chapter in S&W K-frame development.
