There sure is - it's called 'artistic license,' and it requires an unusually strong gluteus maximus musculature, to firmly grasp the barrel, so when you can crack walnuts - give it a try, but use an unloaded weapon, just in case...
Every second-rate movie director has used this trick for effect since they first figured out film could be made to move - but if you just ponder it for a minute - think about the day-to-day mechanics of just going through life wearing the sillyassed rigid thing, much less having to actually use it.
Think about the butt smacking the back of your head and neck as you walk or sit or belly up to the bar - much less mount up, or drive a stage, then think about exactly how the human spine is shaped, and you'll soon figure out just how impractical the whole thing is. no matter how cool the director thinks it is.
