If you have Beyond Light, there is Biting Winds that you can get for completing the Dark Priestess Empire Hunt If you have The Witch Queen, you can get Fel Taradiddle from the Wellspring activity when it is the targeted weapon that day. You could always grab the first secret chest in the Last Wish raid for a chance at Tyranny of Heaven Strident Whistle is a possible reward from doing Vanguard Ops or Nightfalls (Once you have obtained it, you can always focus Vanguard engrams at Zavala) That's pretty much it regarding the sources and availability of legendary bows
