I had the Hogue rubber monogrip with the finger grooves on my SRH .480. I found that when I shot it without a glove on my shooting hand, I got some hand sting. Since I shoot hot .44 loads in my SBH with smooth grips and have no trouble at all, I surmised it might be due to the rubber sticking to my skin and yanking the meat of my hand around during the snap of recoil. I tried a Hogue wooden finger groove monogrip and love it. My hands are a little small for it, so I noticed that my thumb tends to rest along side of the ridge under thumb groove instead of in the thumb groove. Consequently, after 40-50 rounds, the side of my thumb starts to get a little sore from being thumped by the wooden ridge. Regardless, it is much much better than shooting with the rubber monogrip.
IMHO you might like the wood grip better than the rubber one. But, as they say, to each his own!
