Good suggestion about McGivern's book, I have it and have enjoyed studying it. As far as how hard I grip, I've tried I've tried gripping as hard as I can but that makes trigger control much harder. McGivern suggests a moderate grip pressure. I do hold the revolver so that it is in line with my forearm and with the top of the backstrap even with the web of my hand, so that my grip is as high as possible. Normally I use even pressure among all four fingers, but I've tried pressing extra hard with my pinky or with my middle finger. I can't vary the placement of my trigger finger much. If I have the gun lined up with my arm, I can only engage the trigger with the last pad of my finger. On a GP, it hits at the first joint.
