well if you go by the Help Tutorial:

"Accuracy affects anything that has to do with hand-eye coordination. It helps in combat with how well you can hit a target, as well as how well you can place a bullet into someone's body. Any crime or other feat of accuracy is also affected by this attribute."


by saying " It helps in combat with how well you can hit a target, AS WELL AS how well you can place a bullet into someone's body"

That suggests that accuracy helps both guns and meleeing
