Smith & Wesson Model 648 22 WMR 6" 8-Rd DA/SA K-Frame Stainless Revolver

The Smith & Wesson Model 648 is a medium K-Frame revolver chambered in 22 WMR, purpose-built for target shooting and small-game hunting with the Winchester Magnum Rimfire cartridge. Built on S&W's proven K-Frame platform, this eight-shot revolver pairs a 6-inch full underlug barrel with a stainless steel cylinder and frame for a lifetime of accurate, corrosion-resistant service.

The 648 runs a traditional double-action/single-action trigger with an exposed hammer for precise single-action let-off, while an internal lock safety is integrated into the frame for added peace of mind during storage. A classic Patridge front sight sits atop the barrel rib paired with an adjustable rear sight, giving shooters a crisp, intuitive sight picture for rimfire precision work.

The 6" full underlug barrel is matched to a stainless cylinder holding 8 rounds of 22 WMR, giving the 648 a balanced overall length of 11.10" and a heft of 46.20 oz that helps soak up magnum recoil and steady the sights on target. The all-stainless construction carries through the barrel, cylinder, and frame for a clean, durable finish suited to long range sessions.

Handling is finished off with black finger-grooved synthetic grips shaped to fit the K-Frame and provide a positive, comfortable hold for extended shooting. Combining S&W's time-tested K-Frame action, rimfire-friendly shooting, and stainless durability, the Model 648 is a refined choice for plinking, hunting, and casual target work.
