What holster do you all recommend?

I just purchased my first firearm this past weekend and did a lot of research and went with the echelon 4.5F and I will be getting my CPL soon. As a soon to be CPL owner what holster do you all recommend? Something comfortable and concealed, I have a stomach so I’m not sure if a AIWB will work but I also don’t want to buy a lot of holster that don’t work.
