Re: Lcr/xs grip " problem."
Some folks advise choking up on the grip. Well, I've tried this with disastrous results. Accuracy was terrible and I gave myself a painful bursitis at the base of my thumb that took several weeks to heel. So my advise is to not choke up on the grip. Find something that gives you a smooth and natural trigger pull.
I've also tried the high thumb index similer to how one would shoot an auto. Meh, I get the best comfort and control with the traditional revolver style, thumb curled down.
