He honestly missed an opportunity. Because it isn't a gun and really doesn't operate like one, he had a world of design to work with. The reason rifles and pistols are the standard shape they currently are is because of the way they operate. He could have made a blow dart type or something you wear on your wrist, or even some bizzaro impractical shit like battlefield earth. He went with the classic pistol revolver design which tells me he didnt put much thought into it beyond "I want it to shoot something"
