Mean Arms Endomag 9mm Thumbsaver Loader

thingiverse

When I built my AR9 using a standard AR15 lower, I found the Mean Arms Endomag Inserts, which allowed me to use a standard Magpul Gen2 or Gen3 5.56 magazine to feed my 9mm AR. The problem was, there's no easy way to load them; the ejector that is built onto the insert makes it impossible to use any of the "speed loaders" designed for 5.56, and required me to stuff one round at a time in, which really took a toll on my thumbs. I remixed the speed loader portion of this thing https://www.thingiverse.com/thing:3071657 using FreeCAD to assist in pushing the 9mm rounds down into the mag. It still only loads one at a time, but my thumb is a whole lot happier at the end of a loading session.
