Here's something for the slippy-slidey feel: Try Butcher's Bowling Alley Wax. A thin coat will give you enough grip to assure consistency. Warning - too much and you make the wood slippery. If it happens, just clean the excess off with turpentine.
I use this wax on all my SA guns' grips. It grips OK, and then lets go when the gun recoils. No recoil in the .22, but I still like the way the grip feels with this wax.
