I own nothing with a barrel less then 4in, I'm kind of a stick in the mud though. I think they are fun to shoot I just don't see a place for them on my belt or in my pocket as the case may be. I want 45acp, 44mag/spc, 45lc, 357mag. 44mag 240g jhp or jsp at right around 1000fps is about the perfect SD round for my money. To get that out of a 2in barrel would require a bit more of a boom.
38 out of a 2in is a pleasure to shoot for anyone I have ever taught to shoot but I have gotten rid of all my snubs. If funds were endless I would own one of everything though
