How G1 Prime Holds His Gun

Out of curiosity, those of you who have/ had a G1 Optimus Prime, how'd you put his gun in his hand?
As a kid it always bugged me that he couldn't hold his gun straight. I tried placing it with the gun stock both inside and outside of his forearm. I eventually decided I liked the stock outside his forearm so the barrel pointed inward. What about the rest of you?
