Bob,
Gorenut nailed it. They are Nill grips (google their website) and were around $150 if memory serves. They feel great and look good too. Great grips for the money thats for sure. They grey laminate looks good with the satin stainless, and blue was the only color option if you went with a laminated wood, so not much choice there. I think they were model SW036SH4S, but check their website to confirm.
Nill Griffe - Replacement grips with closed back for revolvers
I have a few of their other grips that are all generally their S&W closed back replacement grip. Here are a couple other variations. Top is a Hemphill design and the lower is their fingergroove rosewood replacement style.
The only downside is the 2 month wait on all orders from Germany, so order them well before you expect to see them. I recommend them highly. They are VERY high quality and fit great.
