The most advanced semi-auto pistol in the world, the Model 840 is derived from the successful Taurus OSS pistol, designed for the U.S. Armed Forces, but adds an external hammer. Thanks to Taurus inovation, if you have had a hard primer and the gun misfires, the 800 Series pistols sense this and automatically gives you instant Strike Two capability by resetting the trigger for automatic double action re-strike. Research indicates a 93% or better chance the round will fire on re-strike and when it fires, the 800 will automatically revert to single action by itself. The 840's ambidextrous 3-position safety has positive dentents for safe, fire, and decock. This double-action pistol features Novak 3-dot sights and a decocking lever and includes the original factory hard case. Its grips, metal, and bore are all in very good condition.
