Another option is to go to a saddle shop and they will make whatever you want.
Make sure to specify it needs to be stiff to support a pistol.
They can make them double thickness and stiffer with certain designs.
For a non-leather option, the Wilderness Instructor belt is wonderful.http://www.thewilderness.com/belts/original-instructor-belt/
If you are going to open carry, please look at a restraint holster with at least Level 1 retention and then practice, practice, practice drawing with that holster.
Also, learn how to guard your pistol. There are some ok videos on youtube as a starting point.
