The issue I've always had with the 2" J-frames is that by the time you find a set of stocks that give you proper control, they're usually so big that you loose all the advantage of the gun's small size.
Many people use the factory stocks with a T-grip added. I have used this combo, but find its still a bit small for my hands.
The factory targets are great on longer barreled guns as are the various rubber type grips. But on a 2", most are just too big for pocket carry or deep concealment.
On a round butt 2", boot grips are the answer. They're perfect on these guns. The problem is that nobody, and I mean NOBODY, makes boot grips for a square butt J-frame unless you have them custom made.

I have a square butt 2" Model 36. I bought it cheap and it had a set of Pachmyers on it so I didn't realize it was a square butt until I took the goodyears off. Yeah, I know, my mistake.

What I ended up doing was buying a set of well worn Herrett's Shooting Star grips cheap and then cutting off the bottom even with the grip frame. Thus creating my own boot grips for the gun. It works fine. Shoots good and conceals very well. Recoil is a bit stout. I don't shoot a whole lot of rounds through it at the range. But it works just fine for concealed carry.
BTW: last year I picked up a round butt 642 and with the factory rubber grips, it works very well. My square butt Model 36 is pretty much retired.
