For the most part I no longer carry Glock. Having said that, if I were to carry one of my Glocks it would be the G45. I use to carry a (Gen 2) Glock 17 off duty and did so for years. In fact, it was my first Glock. And I carried it daily without issue in a Desantis OWB leather holster. I have a no-name leather OWB holster for the G45 for when/if I get the itch to carry it. It has a 30 degree forward (FBI) cant which nicely takes care of the butt of the pistol sticking out and printing through a T-shirt.
