There have been some runs of 3" Model 13s made with a RB frame. They are on my short list list right now. Of course, the M-13 has fixed sights, but in my mind this is a plus for a carry gun.
There is an "unconfirmed" report of model 36s made in .357 in 1997, not specified if they are 2 or 3". In addition to the model 13 (a K frame), there are model 19s (rare), 586s (L frame) in 3" and model 27s in 3.5" in .357.
