Smith & Wesson has it in their instruction manuals it is safe to dry fire all of their makes/models except rimfire.
I have Ruger revolvers i have dry fired thousand of times while watching tv to get the trigger a little smoother and to do trigger finger workouts .....
Everything i have ever had i have dry fired sans rimfires.
