Dude, did you watch that video or not? Jerry was shooting a .500 S&W. That recoils far more than .357 would in a 4" K-frame. Look at his arms. He is shooting ISO. See how well he controls the recoil.
Did you watch the video of the desert eagle or not, dude? Gun wouldn't run because of a weak limp ass grip, no firm support to keep it running...dude
