I can't wait til October....
Having said that.....with regards to more coarse sight pictures ..... when applied to the realistic social (or anti social?) distance problems and combative use of the pistol the coarse sight pic or Alternative Indexing Methods like using the front sight only, the back plate , corner of slide, corner of the inboard tilted RMR, "Metal on Meat", "Ghost Gun", "guillotine" , etc etc, (basically if you can see it on the gun in your visual cone you can aim with it) all work pretty well inside 5 yards even when moving quickly enough to avoid your opponent's aim. I think what Gabe is doing is taking the sight picture (movie) and going the opposite direction. His sight movie is shot in IMAX HD instead of a sloppy copy shot by hand in CinemaScope. Both make movies but one is a lot less focused than the other. So instead of accepting that holding a post and notch sight picture (while moving) is problematic for the overwhelming majority of folks and instead using Alternative Indexing Methods to visually orient the gun on target, he is instead forcing himself to maintain that post and notch even during movement (which ain't easy) and I look forward to discussing that more in depth in October.
As mentioned by someone previously, you really need to separate lower and upper body. The body acts like a stabilizer or gyroscope so the feet hitting the ground don't make the gun bounce and jerk. Also the trigger press has to be SMOOTH and not be just running amok jerking the gun and trigger like you are milking a cow. Also as mentioned previously ...the majority of shooters really don't have the exposure, training, or reps of doing this to make it work on demand "in the streets" . But within the proper distance envelope it CAN be done. I always chuckle a little as people are "worried" about "shoot while moving" stages at matches...largely because they never practice it...I just take off and shoot because I do practice it. It's not magic, it is just a physical skill that requires exposure, training and practice.
