Since its inception in 1950, the Smith & Wesson J-frame revolver series has been a reliable choice for personal defense. Engineered to accommodate full-power ammunition, these compact revolvers are renowned for their simplicity and dependability. They are available in multiple calibers and feature three distinct hammer designs, contributing to their status as the leading small frame defense revolvers in the market. In 1995, Smith & Wesson expanded the J-frame lineup with the introduction of the model 640, the first in the series to be chambered for the robust .357 Magnum cartridge. Drawing inspiration from the model 40 centennial, the model 640 is a small frame revolver with a concealed hammer, offering substantial firepower in a compact form. The revolver is aesthetically enhanced with diamond-tipped machine tool scroll engravings on both the frame and cylinder, seamlessly blending the classic features of the original design with contemporary enhancements.
