Anyone willing to hook me up with Legendary Weapons on XBOXONE?

I am having alot of trouble finding Legendary Weapons. I have tried Grinding and doing all kinds of things. Used up all my Golden Keys…please help!

my gamer tag is TristanY0rk (the 0 is a zero)

GT: matrixneo42

Can you help me as well?

If you have the Doctors Order Mission, and collected all of the slag samples in the Wildlife Exploitation mission, then step inside the Creature slaughter done, and then head to the animal holding cells in the preserve and farm the loot midgets. These have a good chance of dropping rare weapons.

gamer tag?
