Sorry but I don't have one to tell you about. Just my thoughts, a cartridge like the 17 rimfires just seems like such a waste of the cartridge's potential in a handgun. In a rifle they are capable of up to 200 yard effecivness and MOA accuracy. In a pistol, especialy a revolver you will loose a lot of the potential. But that said I'm sure it would be fun to play with. Which 17? HMR or HM2? hm2 ammo is about half that of HMR.
