My error. Since the thread title was asking for recommendations for the best speed loader for Glock Magazines, I was focused on that subject and completely missed that that you were relating your experience with a completely different platformI haven't used a Glock loader, but I believe that the lip around the periphery of the Makershot loader would make it easier to use than the Glock loader. But otherwise it's a similar design. As long as they got the pusher located properly it should work fine.
