I agree there is no real reasoning why xur should sell it. My statement was more for the people who already have it. If you got your gally after 1200+ hours by all means your earned it that's a lot of game time. But for those who completed a few night falls or raids and it was dropped lets get real you got lucky but that's rng for you. If you have it already don't be upset if he ever sold it, the chances of him selling it are just as much luck as you getting your gally drop after doing 1 nightfall. I could see if you grinded countless raids for one and he sold it you'd be upset I would too but everyone should have there shot at a weapon. Either way best of luck to everyone.
