I feel as though it might even be just as helpful if there was some kind of handle that could be clipped on to the side "helper" buttons of the magazine...just something that could take the stress off your fingertips.

I envision some kind of plastic/metal device that would allow you to compress the follower by placing the magazine between your pointer and middle fingers, then applying downward pressure to load. Almost like a "trigger" on each side of the magazine.

Just a thought...
