With 57 years of owning and shooting firearms, I've dryfired everyone of them till I was comfortable with the trigger. In all that time I never damaged one and don't know anyone who has. Lots of stories of a friend of a friend that knows a guy,etc, but not one first hand experience. My Ruger Super Redhawk manual says it will NOT hurt the gun, My Taurus 605 has the same traverse bar between the hammer and firing pin but the manual says it WILL harm the gun. Any first hand experience out there?
