A handheld training pistol specifically designed to train the user to anticipate the transition from double-action to single-action experienced when shooting most semi-automatic pistols. The training pistol includes a blocking bar (19) that prevents full forward movement of the reset mechanism, causing the training pistol to simulate a single-action trigger pull. The training pistol further includes a decocking system that allows the user to transition the training pistol back to the double-action or starting position. The training pistol is made of some type of brightly colored plastic with weighted inserts to provide a realistic training device.
