Dude... gravity? He's able to fly, there's no question about it. All he has to do is point gravity's force to where he wants to.

Might not be probable, but I think it would be quite cool that way.
If eclipse's translation in the first episode is correct, Touma did claim that his right hand was capable of dispelling a railgun.
