With brian you don't need any weapons apart from the 3rd and final thing you help him with. You need a weapon for all of the missions for random people apart from cherise and llyena faustin. You can use fist's as you don't need to kill anyone. You don't need a weapon for jeff, sara and marnie. All the help you do for these mean you need no weapon at all. I would strongly reccomend you to carry at least a pistol around everywhere with you and go to the gun shop if you need more ammo. I normally use a machine gun for gracie as you kill more than one person. The rest you mainly only need a pistol. Make sure you collect the money that the dead guys drop as the money could be classed as a reward in some way.
