Next time you do one of those, do me a favor. Dont let your arm move with the gun and see if it still happens.
My contention all along has been that limp wristing has nothing to do with the wrist at all, but with the arm moving rearwards with the gun, absorbing the energy necessary for the slide to cycle.
Your arm moves rearwards with the gun in every shot in that video.
Prove me wrong. I can take it.
