Such as it is, the Hawkmoon has just a perceptibly better (a few feet more) range than most hand cannons right now (I tested every hand cannon I have on yellow bar Hive ultras to map range fall-off and impact values). If you carefully-carefully pace your shots, let your opponent get to within spitting distance, and be spectacular in your aim, you'll get a kill now and then. Most other primaries will serve you better.
