My wife won't shoot my heavily checkered, whether wood or rubber, gripped revolvers claiming they hurt. The smooth with finger grooves Hogue wooden monogrip I have on my 4" 625 (.45ACP) is fine with her. She is 5'10", so the larger grips, and most wooden grips will be at least as big as those stock grips on your 686P, are barely acceptable as well. She did like the wooden 'boot' grips I bought for my 296 liteweight .44 Special, but never fired it to find out just how much more painful they are. Recoil - and your grip size - are things to consider. If you have a dealer who stocks those Hogue monogrips, ask him to try them on your revolver - it just takes one screw. If they fit your hand, they are great. If no one locally carries them, try Brownell's (mail order - or 800#)... a friend did so - and returned his for a credit when he didn't like them. They are decent folks to deal with.
