I believe it my random drop Shadow Price with outlaw and the perk that speeds up reloads on an empty mag. Absolutely loved that thing and used it exclusively for the first 3 or so months after destiny released. Now it sits in my vault collecting dust since its only 300 attack. Really wish there was a way to breath new life into pre dlc legendaries. Kind of like how xur offers upgrades for exotics, we should have a similar option for legendaries too.
