For short waits and a great value, +1 for Jim and the girls at The Beltman.
Also look at Wilderness Tactical Instructors belts, although they may be similar to what you already have.
You won't find a good leather gun belt on any store shelf. Look to the good, custom leather makers as they use the right leather and more important, the right construction. Some even go as far as cutting them with the curve so they are comfortable form day 1. I have 2 from The Beltman and one from Gary Broomeland and 1 Wildeness for casual wear and I had one from Milt Sparks. The Sparks belt I sold because it was a little too big, but I had gotten a sweet deal on it then sold it for 2x what I paid!
