Smith & Wesson J-Frame revolvers have had your back since 1950. These small revolvers were designed to fire a full power round and are as simple and easy to use as they are reliable. Available in various calibers and with three diverse hammer designs, it is no surprise that the Smith & Wesson J-Frame has become the most popular, small-frame, defense revolver on the market. The M&P340 NO INTERNAL LOCK is the latest innovation of the classic J-frame Centennial AirLite revolver. The M&P340 is equipped with XS Sights, which enhance sight acquisition in all light conditions.
