There are some weapons out there that you shouldn't dry fire ...... such as a Colt Double Eagle (double action 1911 pistol) I used to own (regret selling it every day since). The firing pin has a step in it that travels too far when dry fired and hits a similar step in the slide, which damages the firing pin. Most though will not hurt anything by dry firing.
