Just some pointers from a fellow shooter: You should use the pad of the finger and not the first joint to pull the trigger. Gently increase pressure on the trigger until the gun goes off, don't snap the trigger. Do not increase or tighten the grip as you pull the trigger. On a two handed hold the pressure should be about equal with both hands. If you can dry fire the gun watch the sights for movement when you pull the trigger and try to figure out what you are doing to cause the movement.
