If yours is a hammer spured model (DA & SA), you might try some solid bench rest SA shots using the first pad only of the trigger finger for let off. I understand that most right handed people tend to shoot low and left when shooting free hand. I find that wrapping my left thumb behind the right thumb (shooting hand) and concentrating on a straight through trigger pull has straightened out my shots. Thought I still tend to shoot a little low. This provides for a good solid grip, and for me, gets my left thumb out of the way of the trigger finger when shooting a small revolver.
I also installed some Hogue grips on mine. Just a little larger than the factory grips, but the ability to get my pinky finger on the grip seems to help tame perceived recoil. They also provide additional fill behind the trigger guard, thus eliminating the beating my fore finger used to take with the factory grips.
Try these things first. If it doesn't improve the situation you might consider sending it to the factory for repairs. I don't think there is any practical after market or do it yourself way of correcting this situation with a fixed sight revolver.
