Although such a thing is not strictly prohibited, any more than there's a rule that you can't pull a weapon out of a Bag of Many Things, there are better ways of arming yourself  ;D  You're still subject to the 50 Percent Rule on Shoddiness, and since it's the<em>Coat of Arms</em>holding the weapon rather than your character, you'd use your Shtick instead of Fight or Fire Gun to wield it.<br/><br/>Luckily, this is Toon and not Hackmaster.  Or Phoenix Command.  And an out-of-control mechanical arm jutting from your breast pocket with a revved up weed whacker is not the same sort of social disadvantage it would prove in a 'saner' RPG.  ;D
