I have always pulled my shots to the side. I never cared for the death grip, as I don't find it an enjoyable way to shoot, and I am not up for doing grip-stengthening exercies.
I watched this video and changed my grip. Also, I now know I was milking the gun when I pulled the trigger. For now, I am keeping my support hand fingertips just off the grip.
Bottom line, my shooting has dramatically improved.
