I see that you have Shockwave holding his sling shock like a gun. But there is a way to make it where he has his gun arm. There should be a small strip of extended plastic near the handle. Now look at Shockwaves lower arm that becomes the jet. If you flip his hand in, there will be a strip of space between his wrist and the arm. That is where the extended plastic on the gun goes. Just place the gun handle where the hand would be and it should snap into place. Same for tthe other arm. It'll be some what tight in there, so it might take some wiggling to get it out.
