I'll looking at getting an "instructor belt" to use with a handgun holster, which I'm also shopping right now. Anyway, the holster I'm most interested in has belt slots that are 1 3/4 inches. Do I need to get a belt that is also 1 3/4 inches, or something slightly less wide (maybe 1 1/2 inches) to easily pass through the slots? Or does it really matter? Thanks!
