This is Leia's sporting blaster. It only has one grip. The position of her left hand in the second picture gives the impression of a second grip, though none is visible.
Sorry folks. No variation here.
Back on topic, I'm glad to see Hasbro offering what I consider to be definitive sculpts of these characters. Changing the accessories might seem like dirty pool at first, but it's definitely an improvement over pricier CommTech chips and impossible-to-find 2-packs. I'd sooner see quality figures reissued than arbitrarily resculpted.
And you can't have too many Darth Maul figures. In Episode III, Mace Windu unveils his legion of Sith apprentices (apprenticii?) to defeat the Jedi left standing from the Clone Wars once and for all. Buy 'em up while you can.
