I wish I could help you out, but I have the six shooter, not the ten. I use HKS, so you might try a search for them. The 10 shot seems to be supplanting the six from the S&W catalog offerings.
You might try searching for the 17 (blued version) as it was only a ten shot last I looked, thus some companies may not have 617 listed properly as being either a six or ten.
