I'm not sure how the weapon_upgrades.xtbl file will look for SR4 but with the ability to change things up (skin textures and what not). Would it be possible to add in a set that will give or remove the "<Flag>dual wieldable</Flag>".
I know in SRTT this is actually in the weapons.xtbl for weapons that are dual wieldable.
If it is removed from the weapons.xtbl and put into the weapons_update.xtbl as something that can be chosen or removed for each pistol and sub machine gun... Well hell it may be a worked around for not being able to deselect it from the phone menu.
Just a thought.
