Here's the Glock 33 carried at the appendix position. The wedge really tucks the grip into the body- perfect for any double stack pistol!
I saw these two Tuckable Holsters in the Cordovan and Black Leather Textures and had to take pictures of them! The brown is a tuckable glock 43 holsters and the black is for the Glock 26, 27 or 33.
