Wood is always classic, but the grip of the machined G10 is always better than wood (if you don't get smooth or low grip rated G10). Really it's the same deal with rubber; looks poor, works great (except in concealed carry, rubber grabs too much clothing, and hinders draw).
G10 grips are always made in browns, for the traditional wood look.
What I am not a fan of in so many auto grips (especially wood originals)(like your P220), is leaving the top of the grip smooth (and sometimes the backstrap too). I like grip everywhere.
VZ tactical diamond grips on my N frame Smith.
VZ alien grips on my 1911.

I'd have them on a couple more, except they have the Crimson Trace laser grips, which are not my favorite grips (except for the laser part).
A nice upgrade when changing grips is to get hex head screws to replace the slotted ones.
This is all that got added to my P220.

Jess, I've ordered several of these VZ Grips recently Ruger SP101, Ruger GP101, Smith Model 66-2, Ruger Super Redhawk.
The picture on your Smith N Frame, That looks like the my VZ320s I have on my Model 66-2. The VZ Tactical Diamond are a more aggressive texture than the 320s (for my models) They are VERY grippy due to the fact that we can cut the diamond pattern a lot sharper in the G10. (too grippy and sharp for my girlie hands) Funny thing is, they are different for EVERY model??!! I like the shape and grooves of the Colt Cobra Operator or Twister versions the best, although that tough aggressive look and grip is only available for the Colt. I have every Ruger model for all Ruger frames and the smallest (SP101) is the one I like the best, with the best fit/grip/look and would be super on my larger frame revolvers. They look nice, my fit and finish was sub par on all of them. I had to rub/file/cut them to better fit and they had some gaps. I prefer the one piece mono-grips, like Hogue as it provides better recoil protection although lacks in the looks department. Mine are all two piece leaving the hard frame exposed to pound my palm. I don't care much as mine are mostly safe queens now. The only thing we range fire is our .22 rimfire collection. Ammo and affordable shooting are days gone by.
The reason I posted is your post got me thinking and I ordered the VZ Operator II conversion grips for my round butt 66-2, maybe this will provide a little more beefiness converting to the square butt and covering the back strap. Ordered the Black Cherry which should look smart as well more beef and grip.
