Shotguns

A pair of sawn-off shotguns. Based on the quiet report, low damage (at least compared to the full size shotguns used by enemies), and the ease with which the heroine fires one in each hand; it's unlikely that the shotguns are 12 or even 20 gauge. Most likely, the shotguns are of .410 bore, a very slim shotgun shell (equivalent to .45 caliber in diameter, and produces less pressure than .45 colt) which would explain the moderate damage and diminished recoil. The shotguns don't directly resemble any real-world weapon, and instead share the custom-built red monkey theme of Rubi's other weapons. They can be upgraded for damage, fire rate, and ammo capacity.
