If I could find a 4 inch 32 barrel like Hondo's one of my J frame 32 would end up milled for a J frame rear sight assembly.
Even barrel blank with a suitable twist is hard to find, I bought a old 32-20 rifle barrel to get some for my project 32
a 10-7 transformed with a K22 barrel made into a sleeve
I think you might find a Ruger or a maybe a Taurus 32 with adj sights for under a grand. It would take luck to find a Smith for that. But, I just combed through gun broker and right now the only DA 32 cal was a Ruger GP100 in 327 Federal for $1800, there were a few Ruger single actions.
