Bonded Object and Firearms question

[rat_ bastard]

Lets say you have a bonded object, and you want it to be a weapon and for whatever reason you want it to be a pepperbox. Is a 3000 gp firearm a legal selection for a bonded object in a game where firearms are allowed?

Can you tell me why it would be Illegal?

I can't find any rules against it. Pity.
