I'm going to be getting a G1 O.S. soon, but I've noticed something. In some different pics and artworks I have seen where the right hand and left hand will be switched. Where most of the time the claw is on the right and the blaster on the left, sometimes I see where the blaster is on the right, and the claw on the left. Which is correct? Does it matter? Can the shuttle halves fit on either arm?
