Went there, read that, shrugged and thought, "Four inches?? Why not add six or eight inches while you're at it? Just throw in a couple of extra holes for use until you actually become morbidly obese, and you're covered for the next 150 pounds" (I even think sarcastically)!
True enough, anybody could guarantee a "perfect fit" with a belt that was 4" longer than one's waist measurement. The seller could probably guarantee it for the next gain of 80 pounds or so! The Pillsbury Doughboy could use a belt like that...
I buy my gunbelts measured for IWB carry (yes, I do carry fully concealed during the Utah winters), because IWB carry is when you'll truly need some extra length on your belt. Hip holsters don't add diddly-squat to your belt size. How much extra do you really need? Two inches... unless you're carrying a MAC or Uzi inside your waistband. There is such a thing as "too much of a good thing", and an additional 4" of belt is exactly that... unless you're planning on a significant weight gain in the immediate future. On the other hand, you get four feet of "Bullhide" belt for the same price as three feet, so the extra 4" in length may be good insurance without any additional cost. Just my thoughts on the matter.
