I think we may both have been looking at the same sites recently. My idea would be that you cut the glue stick into a small dime size and put it in your EDC. I have tried using the hot glue guns to repair picture frames, broken Christmas decorations, etc. They are so messy and don't hold anything together well. I could find many other things that I could use that space for in an EDC. Now I could see carrying a small tube of non-toxic super glue in a FAK. It's basically the same thing they use to close wounds in the ER. Especially on the hands and face. Plus super glue works a lot better at keeping other day to day things together.
