Crossbow, Hand: You can draw a hand crossbow back by hand. Loading a hand crossbow is a move action that provokes attacks of opportunity.
You can shoot, but not load, a hand crossbow with one hand at no penalty. You can shoot a hand crossbow with each hand, but you take a penalty on attack rolls as if attacking with two light weapons.
