Yup, that's right! According to the guy on the phone at S&W back when I bought it as a spare for my 646 it was the last one in stock. I called a year ago for a friend and asked after a spare (didn't want to sell mine yet) and they said "good luck finding one".
Well... My friend did a custom Ruger and I am clearing out stuff I never use. I am also letting the 646 go and would consider a bundle on both...
I will let this go for $350 plus shipping.
