You might try Numrich (Gun Parts Corp), and also list a "Wanted to buy" here on the Forum. The 17-4 is new enough there may be some floating around. I think any K frame rear sight of this same vintage should work, but you may have to change out the blade for correct height. I have a 17-4, so if you need any measurements PM me.
