Modern S&W seems to be swinging and missing a lot (from my point of view) with their round-gun offerings. But the following is the top of my charts:
The current 19-9 4" seems to be well designed and reviewed. There is also a PC Carry Comped version in both 2.5" and 3". But I'm baffled why there is no comp-less 2.5" version? Considering this was one of the top concealed carry and off-duty guns back in the day, it's baffling to me. A 19-9 2.5" with a matte finish is high on my "they need to make this" list. And don't give me one of those 2.75" barrels like the 66-8. It just looks weird.*
*(although I have considered buying a 2.75" 66-8 and getting it C&S to Cerakote it.)
