Dvorak Instruments introduces a semi-auto dry firing device that allows officers to dry fire most popular handguns and rifles 3,000 times an hour. It is designed to develop trigger control, precise shot placement and rapid fire technique nearly overnight at 1-percent the cost of live ammo. The patent-pending simulator replaces the barrel or bolt and magazine and uses CO2 to cycle the slide. It fires a laser dot activating an electronic target. After a training session, the system can be easily removed from the weapon. It is available for handguns made by Glock, Beretta, Sigarms and for AR-15/ M-16, HK-94/ MP-5 and M249 weapons.
