Just started using this Lula mag loader. Wow, what an improvement over the Colt style loader. It's actually a pleasure to use. Lula where have you been all my life.
Their UpLula is a great all purpose loader for hand gun magazines, however you if take a dremel tool and open up the sides of the loader, as well as remove the spring tensioned guide, it can be used to load Grease gun magazines.
