Losing weapons for a toy SUCKS. Been there. Can I make a suggestion that will help ease the loss? Consider buying third party weapons (guns are easy to find) or a printed pair from shapeways. Lots of Dinobot Grimlock swords that would suit. Or even take the Generations Grimlock sword - it's pretty close to Planet-X'w one though you still need a gun. Maybe a spare Arms Micron?
