This is Selene, the Death Dealer from the Underworld movie series. She is a vampire who hunts down Lycans (or werewolves) in a world where there is an ongoing war between both of their species.

Kate Beckinsale played this action movie heroine in 4 films: Underworld, Underworld Evolution, Underworld Awakening, and Underworld Blood Wars.

Recipe:
Body: DC Collectibles Pandora, which already had the holsters and the 2 guns
Head: Ms. Marvel with added hair from DCU Katana. I removed the mask and repainted to resemble Kate Beckinsale as Selene.
