Simple RAW for Pathfinder Thread V: Golarion Strikes Back

[rs2excelsior]

Q373: are there any rules for the interaction of two-weapon fighting and ranged weapons? Specifically one-handed firearms and hand crossbows, either dual-wielding them or wielding one alongside a melee weapon. Do they count as one-handed or light for the bonuses, or can one not use the TWF feat to attack with both sword and pistol in the same round? The combat section has notes for which thrown weapons count as light or one-handed when being dual-wielded (dual-thrown?), but not ranged weapons capable of being fired from one hand.
