I have a question for anyone who has played the console version of this..if you dual wield pistols, when you shoot can you draw only one pistol? Or if you are dual wielding do you have to always draw both pistols?
I rarely dual-wielded but IIRC you can open up the weapon wheel (time slows down then) and select the left or right short weapon or the dual-wield option between them to draw both. You can for example use a sawn-off shotgun and a revolver simultaneously or you can highlight just the shotgun to draw it.
You can have two short and two long firearms on you (plus throwing knives, dynamite, lasso and whatnot), the rest stays on the horse and you have to equip what you want beforehand.
