Go to www.gungripsupply.com and talk to Tina...their phone number is (704) 843-7119. She has some very nice sets of grips with the S&W escutcheon...tell her that Roger from Ohio told you about her...I am very pleased with her grips...
Blu Magnum Custom Pistol Grips is another great candidate with workmanship that could hold it's own next to a set of Keith Brown grips, which I feel are the absolute best on the market.
While you're looking sites over check Collinscraft Handgun Grips(not certain that's the exact name, a general search will turn him up). Makes great looking grips of just about any material you can imagine.
I just ordered a P220 Sport that has those on there. Sweet. I can't wait.
That being said, the only aftermarket grips I've purchased for any revovler I've owned have been made by Hogue. For the money, I just don't see how you can beat 'em. I've got large paws and there is one style that fills them nicely.
