Now personally, I would go with an SOE Every Day Carry (EDC) Belt or Ares Gear Ranger Belt they both use cobra buckles come a 1.5 inch and will thread through the loops in your jeans or tactical/combat pants. Both belts offer a rigid fit and can handle more weight then you are willing to put on your hips. I run a Original SOE Gear EDC Belt in uniform literally everyday and have had no issues other then I want another. A very good friend of mine runs an Ares Ranger Belt and swears by it. They are custom made to order so it takes a couple weeks but it's worth the money and the wait. Each belt costs approximately $100.00 to have delivered to your house.
Edit - I've had Blackhawk, 5.11, CP Gear, and any number of duty and tactical belts they all work for a while and then wear out they end up sagging and your gear hangs funny. The SOE EDC and the Ares Ranger are the only two I have seen last as long as the have and still keep going.
