I would definitely need to find a DAO or decocker only version (see my 3rd post where I discuss the Ruger KP345). I know there are some DAO S&Ws out there. I don't remember if they made any decocker only versions.
The .40 caliber Smith Model 4046 comes to mind and might meet much of your criteria. Sadly, however, the chances of finding one (as you noted referencing a different third generation variant) will require a serious search. But they are out there and it's not that unusual to see them at affordable prices at major gun shows.
