I'd like to buy a simple thumb-saver tool to help with loading mags for my Ruger MKIII. Also, I want one for a MKII, as I'd like to buy one for my Dad's pistol too. Perhaps the same tool would work with both. I have something made for my Makarov, a flat piece of oval shaped plastic with the center cut out, that fits/slides perfectly over the Mak's mag, simple and effective. Something along these lines is what I'd like.
