I've always heard that its not good to have your trigger finger contact the frame or the trigger guard. This would cause you to push shots as your finger drags on the frame during the trigger pull. My index fingers are not straight and curve toward my middle fingers. This makes it nearly impossible to keep my trigger finger from contacting the frame above the trigger area. This does not happen with a 1911 since the 1911 frame is much slimmer. I tend to push shots left and low with a Glock and although I need to dry practice and live fire practice more I feel like I know what a good trigger pull is and can do it. I'm not keen on 1911s so I figured I just needed to find a different platform that allows my trigger finger to only touch the trigger and not the frame. Then, I'm watching some Bob Vogel videos and it looks to me like his trigger finger is touching the frame too.
Yep.
So is it the norm for Glock shooters to have their trigger finger riding the frame through the trigger pull?
