Over the last months, initially influenced by the Ron Avery finish flat, stripe drill video, I have migrated to having less finger on the trigger than I previously did. Origami, I believe is also in the less trigger finger camp. This seems to help me press the trigger straight back, faster, and dovetails into my attempt to grip more of the front and rear of the grip, than when I was Vogel-ing it. Less finger also works for me with the Wayne Dobbs drill, quickly pressing the trigger straight back.
Interestingly, on DA/SA pistols like the Beretta 92 and S&W 1076/1066, it seems I want more finger on the trigger DA than I do SA. Without realizing it, I believe I have unconsciously been using more finger DA, and then in recoil transitioning to less finger for subsequent shots. On the timer, this hasn't cost me any time, and seems to improve my ability to press both the DA and SA triggers optimally.
Thoughts?
