Frankly, I always thought the factory wood S&W grips on their snubbies were terrible for achieving any type of hold on these revolvers when shooting, even when shooting tame factory loads.
As Old Fuff says, a lot depends on how you propose to carry the handgun. I use Uncle Mike's Boot Grips on all my snubbies for the range, but these grips aren't always the best for carry, as they have a tendency to stick to fabric when drawn from IWB, snuggly fitting OWBs (such as a good pancake holster) or from a pocket. Rubber grips can also contribute to printing (your shirt may cling to the grips and display a nice silhouette of your carry gun).
I use some fairly inexpensive Ajax laminated silver diamondwood grips (still pretty brutal as they don't help tame recoil at all, esp. w/+Ps) on my two Airweights for carry, but swap out with the rubber grips if I'm going to put more than a couple cylinders downrange ...
