Yes, one has to be a masochist to want to load a Luger mag by hand. Unfortunately my single and dual stack 9mm MagLula's that work wonderfully on all other mags, do not work with Luger mags of any manufacturer.
Lastly, I found that my one repop Luger tool does not work well with my MegGar or other mags. I guess they are for show only.
