The Smith & Wesson J-Frame has become the most popular small frame personal defense revolver on the market. This aluminum-framed 5-shot revolver weighs a mere 15 ounces, yet proves to be extremely accurate and reliable. The 642 is calibered for .38 Special rounds, the most trusted revolver ammunition available. The internal parts on the Enhanced Action model have been hand-polished in the Smith & Wesson Performance Center for added smoothness. The grips are wooden with a custom basket-weave pattern.
