Yup, anything from maglula is the way to go. Several years ago I was a ground combat skills instructor for airmen deploying to the AOR working out of Camp Guernsey, Wyoming. We had to load a LOT of M9 mags with simunitions for both our OPFOR and students. Myself and a couple other cadre brought in our own personal Maglula loaders and it made the job a lot faster and far fewer sore thumbs.
