Good advice on grip on the posts above. Single Actions tend to be more grip sensitive then other style handguns, at least for me. Its easy to "choke" the grip, use to much finger, and end up shooting left. A tip for that heavy trigger pull - Remove the grip panels. Look up near the top of the grip frame. You will see a spring on both sides of the grip frame that seats in a stud. Un-hook the spring from the stud on one side, leaving the other side attached to its stud. This spring is the trigger return spring, and will have no effect on firing reliability, but will reduce your pull by several pounds. I have done this with about a dozen Rugers over the years, and it works well.
