Limp wrist syndrome was not to uncommon among new shooters, many moons ago when I trained new shooters. Ne

When we transitioned to Glocks with their polymer frames we saw a lot more of it. We had to teach people to lock their wrist and resist the recoil more. Those who seemed to have biggest problem were folks who shot heavy magnum single action revolvers. Experienced shooters. When I got my Big Glock 45 ACP I had problems with it. The guns seemed to flex a lot.

As big and heavy as the Desert Eagle is they are shooting in the video, I don't see limp wrist syndrome being a issue.
