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 our latest innovation on our classic J-frame Centennial AirLite® revolver. We took an historic revolver and added modern, ergonomic features making this a lightweight, yet sturdy, carry gun. The M&P340 is equipped with XS® Sights, which enhance sight acquisition in all light conditions. This revolver features a Scandium Frame.
 
Once purchased, we strip the revolver down, polish the internal surfaces and tune the springs, bringing the factory weight from 15-16# double action, down to a manageable 7-8# double action pull wieght.  After tuning, we take the pistol out and test fire it to ensure reliable ignition with factory ammunition. 
Test fires are typically performed using Federal, Remington, Fiocchi or S&B ammunition.
