I would also suggest the S&W M17 or stainless equivalent. I have used one for nearly 4 decades and while I have had others, (a Colt Diamondback comes to mind) it is the one I have kept. Most speedloaders are a bit of a pain for this small of a cartridge. I just keep loose rounds in my pocket or if at a competition, I keep them in bloacks.
Some casual shooters I know, use a magazine for the Ruger auto pistol to carry spare ammo. I have tried this and it did not work for me in 22 caliber. (I do however use a 1911 magazine to carry spare rounds for my M25-2 but that is for another thread.)
