Just forewarning you...a lot of gun ranges don't allow aluminum casings. It has to do with being able to pick up brass a lot easier so they can sell it off in bulk for the reloaders.
I love Hornady ammo...some of the best around!
Good pick with the XD...can't go wrong with that choice! I'm looking at trading one my my .45's for a more compact XD .45!
