I've noticed that when I dry fire my AR the hammer pin sometimes rotates a little. I keep it oiled (hammer, not the alloy) so I'm surprised that it does.
Don't know if it actually matters but I could see the steel pin wearing the aluminum over time. Would ovalize the holes and change the hammer/sear relationship.
