This also adds another foil between Dante and Vergil since it was said in the DMC 4 novel that Sparda didn't like using guns. This seemingly has some justification since in all his demonic appearances, Sparda has never shown to be wielding a gun. So, this sort of adds some depth to Vergil and Dante's difference since seemingly Dante, taking from his father's human side that wielded guns, Dante sees guns as justifiable weaponry while Vergil, who takes from Sparda's demon side which didn't have guns, sees them as unnecessary and unhonorable.
