I've gotten Logan's gun from a red chest, fabled tortoise, cradle and thunderball fists from vending machines. While not a legendary, I've gotten the quest reward Deadly Bloom from Pete before it was awesome.
I've found about 3-5 legendaries in red chests and hit the Jackpot once, it was a Hammerbuster. --- "He never saw Molly again." XBL GT: Hellcamino420 - Currently Playing: Borderlands 2/ Injustice: Gods Among Us
