Cereza really does need more firepower. Her pistols are meant to be a back up weapon, and not a main weapon, since she wants to upgrade her polearm to be melee/ranged. That being said, does anyone have any suggestions? Keep in mind, at either end of the handle are counterweights - one is the computer system which controls the blade positioning and whether it is collapsed/extended, and the other is the power supply. The handle itself has cables running through from the power supply to the computer. It has a handle on the side of the computer housing.

So, any gun form can't use the shaft for the barrel, since it is already in use. But - because of her semblance, she doesn't need a trigger or manual cocking/bullet ejecting parts as that can all be done electronically. Ideas are welcome!
