From personal experience , I had a 460 Encore barrel , 12 " with a tamer ....had rubber grips on the frame, lots of recoil and everything that goes with it ! My son bought me a pair of nice walnut grips and forearm , put them on my rig....stainless and walnut looked sharp.
The first time I took it to the range , I had blisters on my right index finger ( unknown cause ) had a spot rubbed raw on my left index finger ( from the trigger guard )...and several other areas of pain on my hands............Rubber grips went back on , They do make a difference on the heavy kickers Good luck....
