Special Part(s): [Wheelgun Variants] Wheelgun is the title of a group of common pistols in Borderlands 2 exclusively of blue rarity. They are manufactured by Jakobs, and use the Bandit, Dahl, Maliwan or Tediore barrels. Depending on the rarity, this title seems to be interchangeable with Revolver, which is valid for all the same barrels.
