As the Iowegan said, its different for all hands, each person.
I think individual grip styles are a critical piece of the puzzle for balance & recoil. Generally, i too also think wider and oversize helps the most on the bigger boomers.
Have tried narrow Pachmayr rubber grips on a half dozen multiple weight big boomer revolvers and never mastered that grip, with my hands. But the wider rubber Hogue type grooved grip on 454 SRH is perfect for me and my sons
I wear gloves and tape fingers if needed with all Hard grips, some gloves are sticky, some padded, sometimes just ordinary thin/slick sheepskin.
