There are 3 sizes of mini loaders:
DS-484-SLR for the really small short/LR models
DS-530-LR for larger frame mini with .22 LR
DS-530-MAG for larger frame mini with .22 MAG
NAA loaders
It's an option, there are a lot of options with the NAA revolvers. Personally, I've concluded that carrying an NAA that comes with the .22 Mag and LR cylinders is good enough. Once all 5 shots of Magnum have been shot, remove the cylinder, replace with the loaded LR cylinder. If 10 shots doesn't finish the job, nothing else you likely have will.You could always carry a half dozen of them as New York reloads.
