If you really want to see if a good gunbelt makes a difference and don't want to mortgage the ranch to do it, try
The Original Instructor Belt, from Wilderness Tactical Products. The basic model is a 3 stitch design ($34.95), which has been around for 17yrs. It works great. The 5 stitch model ($39.95) is every bit as stiff and secure as the very best, double-ply leather belts. The best part, is that they are thinner than leather belts, so don't impose as much mass on the body. They will never be something you'd wear with a suit, but for casual wear, range sessions and competition, you can't beat them. I know several guys who dress casual for work and that's all they'll wear.
Wilderness is great to deal with and has incredibly fast turn around. Last week they actually
made me a belt and shipped it same day.
