There is no such thing. The 422 & 622 models were offered with fixed or adjustable sights. The 2206 was offered with fixed, adjustable, and a target version. The 2213 & 2214 models had fixed sights. There was also a 622 with a vent rib available one year.

A nice 422 with adjustable sights and wood stocks would bring $300.00+ in my area. I sold one for that a few months ago. I personally would not pay half that for one in need of refinishing.

I have owned nine of this series of pistols, still have six of them. Why S&W dropped them is beyond me.
