Foxy,
A PROPERLY FITTED Wildeness belt will NOT have the same problem you are having with your more generically sized Blackhawk belt. They are fitted to the inch, so the bitter end always finishes in the right spot. In addition, the Wilderness stiched belts are far more rigid and suitable for range holsters than the Blackhawk offering (which is still a decent belt for the price).
