When I wear Vertex pants with a Volund belt I have zero issues. I use the exact same setup with 5.11 pants and the holster won't stay clipped to the belt after driving for a few hours. Has this happened to anyone else? The holster is a K&D that looks like this. http://www.nelsonholsters.com/images/iwb/Dakotann.jpg To me it seems the material around the waistband is thicker on the 5.11's and I suspect the added tension unhooks the clips. I have a Comp-Tac I haven't carried yet. I am going to give that a shot but this is making paranoid.
