The Smith & Wesson M&P 340 is a lightweight J-Frame revolver designed for discreet carry and personal defense. Its Scandium alloy frame keeps weight to approximately 13.3 ounces, while the stainless steel cylinder is chambered for .357 Mag ammunition and holds five rounds. The enclosed-hammer double-action design helps reduce snag points during presentation, and factory night sights provide a visible aiming reference in low-light conditions. A polymer grip completes the compact, practical configuration.
