To me "grit" doesn't have so much to do with ability scores. It has more to do with things like overcoming the abstract nature of hit points (ok, I just fell off a 40' cliff -- what are the repercussions of that besides the fact that I lost 4d6 hp? There's no real D&D mechanic for broken limbs, concussions, stuff like that). It has to do with "adventuring" without some of the standard D&D magic "crutches". Even something simple like light spells or bags of holding. Though I suppose one could argue that one such "crutch" is in fact PCs with higher-than-average ability scores.
