I'm running CT 405's on my 642 UC. Hamre Forge on my 632 UC. My primary use for a J frame is pocket carry. For me the VZ UC grips are kind of large and tend to print more, IMHO the 405's are hard to beat, they handle recoil well, are minimal but adequate and with the laser blink of the eye 5yd and aimed 25yd A zone hits are very doable.
The HF grips suit the application quite well also and carry well.
