I picked up one of these belts -
BLACKHAWK! Molded Cordura Duty Belt - BLACKHAWK! - this winter. You can see it set up in this thread, page two -

The belt is very heavy duty. It has two different points that need to be pressed in order to open it up. This should prevent the belt from ever opening when you don't want it to. There is is what feels like plastic of some sort inside the webbing so the belt holds its shape very well. It is thick, however, and you may need to modify the belt or anything you attach to it.
