Looking to have some frame work- mostly undercutting trigger guards- done on a few Glocks. Is there someone in the Charleston area that does frame modifications?

Geez. I just remembered that I already posted this here a few weeks ago.

I'm getting old.

I can post the link to Dremel again if you need it.    
Seriously though, it's easy once you actually believe you can do it.

You have far more faith in me than I do myself.

I think I may wind up buying a Dremel.

I was really hesitant to do it but then I thought, meh, it's just a Glock.  Worse case you can send it back to Glock and a new frame is pretty cheap, or just buy a Polymer80, it's a much better feeling frame to start with.  Just go slow and keep your hand steady and you'll be fine- so unlike rattle canning a gun, don't start drinking first.    I used the sanding drums, both sizes, before switching to strips of sandpaper to finish rounding and smoothing.  Wear a dust mask or point it away from your face while sanding.

This is a must watch:
