And again with the double-weapon, Aristo: As the others said, it is unwieldy as can be. You are taking two weapons that do not work well together in any way, and trying to mash them together. A sword is meant to be a balanced weapon able to be used with skill. A gun is supposed to be steady enough to shoot straight. Your weapon can do neither. The amount of backlash and penalties on rolls would mean you would probably have to roll natural twenties all day long to win. Anyone at your level or higher would easily outmatch you.
