I've been carrying a full size weapon in an IWB holster for many years now and have simply used my regular 1 1/2" leather belt which I always felt did a good job, until I got this new Nexbelt. I purchased the 1 3/8" leather belt with Aston dress buckle and I am impressed with the added comfort. Honestly I've carried so long that I don't even feel it's there, it's just part of me, but I have had to constantly pull my pants back up and tighten or loosen the belt as needed. Having to make 1" adjustments with the holes in the belt was definitely not fine tuned. Having the narrower belt and the 1/4" adjustments is a totally different comfort feeling and for the past couple of weeks of ownership; I feel confident with how the system works and have found I "mess" with my belt much less than before and my pants stay where they should be. I'm actually considering a second belt now.
