Having not played Kid Icarus Uprising (no 3DS yet), I’m somewhat aware of the jokes and references this game makes. But this is one that could be a stretch. The video above suggests that Pit’s referring to Curly Brace, the female robot you meet in Cave Story who also happens to have a gun. Of course, since this is videogames we’re talking about here, there are plenty of machine gun robot girlfriends to be had. I for one would pick KOS-MOS, who very much fits the bill of machine gun robot. Not sure about the girlfriend part (Virgin Mary and all).
