Honestly, and I am just pulling this out of what I have seen, no. Hunchbacks are actually my preferred hammer system for snub nosed revolvers, but I don't recall seeing any recent production .357's from S&W. I just don't think the market is there for them.
EDIT: This should teach me to look something up before I open my mouth, the S&W 649: http://www.smith-wesson.com/webapp/w...layErrorView_Y
It is in the "Satin Stainless" finish
