I have no experience or fascination with 9mm DA revolvers. The one "niche" that comes to mind is police supply chain. If the police are using DA revolvers (which WERE the standard) then some officers are carrying 9mm Autos, a common ammo may be desirable.
And,moon clip ammo may make for fast reloads. I can't think of any more good reasons for a 9mm DA revolver. 38 SPL and 357 Mag will do whatever a 9mm will do.
