I feel like a dirt-bag, and I admit defeat. Farming this gun for months has netted me nothing. Is there anyone out there willing to duplicate one for me? I'm level 50, so I don't even need a fancy level 61 model.
Doc Mercy doesn't drop it in TVHM/UVHM, it's bugged. Only time he will is from the random loot pool, which means any other enemy has the same chance which is like 0.01.
Its sad, you are the first person to say that and I dont doubt it. Sucks though cause I spent so long farming him. But I guess ill start looking in the torgue machines for a lower level one unless someone can dupe me one.
