Abstract: When a semi-automatic weapon is live fired, its firing pin is reset and is ready to be fired again. The shooter's hands remain in the firing position, and just the trigger finger and trigger are employed. But with dry fire practice, the shooter must remove a hand from the weapon and ratchet the slide to reset the firing pin, allowing the trigger to return to its unfired position. This must be done each time a shot is simulated. This invention provides, by incorporating a modified ammunition magazine in the weapon's magazine compartment, realistic muscle memory training by duplicating the action of the trigger, the feel and the sound of the release of the firing pin and the resetting of the trigger for additional trigger activations. It does not interact with the weapon's firing pin and does not require any alterations to the weapon such as disassembling and reassembling of parts.
