I can carry a much larger weapon and conceal it easier in a more varied wardrobe in the appendix position. The Dale Fricke Archangel was originally designed to carry GLOCKs in the AIWB position. Another option, albeit unconventional is the Zac rig also from Dale Fricke. I EDC a G23 in these options and I have to dress from shorts and a T to suits and everything in between.
While your G20 is larger than many EDC choices it is light weight and will still work with a little thought and pre-planning.
