In the past I have had the problem of pushing shots to the side (right in my case because I am left handed). After experimenting with finger placement, I changed directions...literally.
Instead of pulling the trigger with a "normal" finger movement that applies pressure across the trigger, I now "roll" my finger downward while pulling towards me so that the motion of the finger is along the same axis as the motion of the trigger. Presto! No more pulling of shots to the side.
(Credit where credit is due: I learned this from a post by 9mmepiphany in a thread on TheHighRoad.)
