I'll add to the list... my S&W .357mag... it's like getting beaten in the hand with a baseball bat with every pull of the trigger...
What kind of grips are those? Hard wood? I have rubberized on mind. It is not punishing to shoot. I put 150 round threw it last Friday without an issue. I don't know where you are located but itf it is close to South Bend you are welcome to try mine and see if it is better.
