That would be 'Y', but holding down that button takes out your heavy weapon, so doing this would effect drawing your heavy weapons. They should just get rid of the useless emotes, or require another button to be pressed with the arrow to perform an emote, then we could use the dpad to navigate your inventory without going to the inventory screen, just draw the weapon you want to change, then use the dpad to switch to another weapon in the same class. Edit: I can see this done quite easily in two ways. 1) As explained above, use the dpad to instant switch weapons and require the right stick to be clicked and held when using the dpap to perform emotes. 2) Alternatively the right stick can be clicked to cycle through weapons in the currently equipped weapon class. I would prefer #1 over #2 as you could move left and right through your weapons, and if they remain mapped like they are in the inventory you could also move up and down making for very fast weapon switching.
