Borderlands 2 E-tech Pistols (Eridian Weapons)
Three E-tech pistols, E-tech pistols in game have Spiker, or Dubble Spiker in their names. (the second pistol is a quest reward for doing The Lost Treasure quest, I'm not sure if you get it 100% of the time for doing it because the reward was a GREEN pistol but I got a PURPLE E-tech pistol.)
