I use an Uplula to load all magazines. When loading single stack magazines they get a little wobbly in the Uplula. Since I have extra magazines for three single stack pistols I though an adaptor was in order. Pictured below is an adaptor that attaches to the bottom of the Uplula by friction. The material is plastic similar to Delrin. It was made on a bandsaw.

That looks nice! That's good to know. I use an Uplula too but haven't had any issues.
