I think it works yet same way the one I have for My Ruger 10/22 mags. The shaking helps align the cartridges in the loader. No sharp edges inside, it takes a lot of pressure to set off a rimfire. My thumb doesn't complain when I load my MKIII mags, and I load all five in a row, so I haven't bought one. Loading rotary mags is a hassle, so that loaders a thumb saver!
