Yes you will definitely need a belt designed to carry a gun. I have one from comp-tac that has kydex sandwiched inbetween the two pieces of leather. Night and day difference over just a belt to hold your pants up. Losing weight helps but I would experiment with position of the gun and see if it's any more comfortable. I know it feels like everybody knows you have a gun on you at first but you'll get used to it. Remember, bend at the knees when picking stuff up.
