Dry firing is part of the take down procedure. Since the XD is a centerfire pistol it shouldn't be too much stress on the firing pin, unlike what would be going on in a rimfire pistol. Most will agree that dry firing the XD isn't a problem. Just for a little "insurance" a set of snap caps would be a good investment.
Once again, don't forget about the lifetime warranty from Springfield Armory. They got your back :mrgreen:
The roll pin that holds the striker in place might be subject to additional wear if dryfiring, no one seems to be quite sure. It's easy to replace, but if you are going to dry fire "a lot", I'd have a spare on hand.
