Life of this patent

Estimating the term…

Abstract

Live firing a semi-automatic pistol, resets the firing pin, and the semi-automatic pistol is ready to be fired again. With dry fire practice, the shooter removes a hand from the pistol and ratchets the slide resetting the firing pin to simulate each shot. This invention provides a simulated ammunition magazine that provides realistic muscle training by duplicating the trigger action of normal live fire, the feel and the sound of the release of the firing pin, and the resetting of the trigger for additional trigger activations. There is no firing pin interaction, and no alterations required to the pistol. This dry fire training device is narrow enough to work in single stack pistols.
