I was using a belt from Dickie that was a lot thinner and my holsters weren't riding very comfortably. I invested in a belt from Midwest Leather Works, a local company and also a NFOA sponsor, early on and years later I am still wearing it. It is an incredible belt that I will have to replace soon only because it is now too long because of my losing weight since I bought it. Matt was great to work with and really knew what needed to be done to fit me.
