In defense of GLOCK
I certainly believe that limp wristing is a real phenomenon. In the case of the GLOCK, it's because the frame is light. No, not light. Really frikkin' light! Anyone who owns a GLOCK will recall the surprise they had the first time they field stripped it. When the slide comes off the frame, you end up looking at the thing to make sure the insides didn't accidentally fall out. The other part of the equation is the GLOCK has a pretty beefy slide. This means it moves slower under recoil (and the lighter recoil spring works for a longer duration of time, spreading out the felt recoil before the slide finally hits the frame rails).
For a gun to work, there has to be a big enough combination of mass and reciprocal force to keep the frame from being pushed by the recoil spring, causing it to follow along with the slide. The "Limp Wrist" videos posted on page 1 of this thread demonstrate how the 1911 design very thoughtfully incorporates enough dead weight in the frame so that their pistol might cycle even if held improperly. Afterall, you never know when you might need to take a shot with just your trigger finger, as the grip safety rests precipitously against a twig. Or perhaps, your hand is completely paralyzed except for your trigger finger. It's comforting to know that as long as your 1911 pattern gun is "one of the good ones" and has been recently cleaned and oiled, it'll be ready for a quick followup in the above scenarios (if the gun doesn't fly out of your hand on the first shot), particularly considering that you may find it difficult to hit your intended target in this fashion within the first several shots. This calls for a lot of practice in SD drills in preparation of SPH - spontaneous hand paralysis.
The GLOCK designer very rashly took this essential weight out of the frame, expecting a semi-functional hand to always be there, at least somewhat wrapped around the frame, when fired. Thanks to this video, we all see the clear deficiency in this line of thinking.
If there proves to be enough admiration of the 1911 design based on the merits of this video demonstration, I will start plans to develop a BUG with the ultimate in concealability. It will feature a zero finger grip. It will be held only with the trigger finger, and you fire it by pushing the gun violently at the target, then quickly pulling back. Of course, it will be chambered in .44 magnum and can be had with optional laser sight and Hogue trigger-sock.
