My best bud has Pachmayer rubbers on all of his "N" frame magnum (and 25-5) revolvers.
I know "recoil absorption" is quite subjective; I can't argue with my friends choice, in terms of recoil control in a hard recoiling revolver.
However, I can't bring myself to have rubber grips on my S&W's.
Like others, I favor Herrett's "Troopers", or "Shooting Master's" that cover the backstrap and spread the felt recoil over a larger area.
