Low profile and gun belt are two diametrically opposite things in some minds. There is justification, too. A one pound gun with holster takes a stout piece of gear to support it and the pants hanging from it.
Load up your EDC gun, holster, belt, what you stuff in your pockets, etc and weigh it. The pants are the least of our problems. To keep them up we have to use a stiffly constructed piece of harness to prevent it from folding over, and it has to keep the belt above the hips so they are wider than the waist.
That last part isn't going to happen for a lot of us. We are too much a tapering funnel - cinching up the belt doesn't make it work better, it just adds a lot of discomfort. The best belt in the world won't fix it.
Since that isn't admitted or even recognized at a certain point in life, it has to be mentioned. It may not be the belt - it's doing what it can against stacked odds. At that point a factual reassessment has to be made. That may happen at any age, too, depending on the health and lifestyle of the carrier. Plenty of younger guys discover this situation exists before they even buy their first firearm.
That's why belt carry simply isn't a choice for a lot of us, and when we do, it's a battle of tug here and pull there to keep from losing our pants. All of which are tells we carry, dead giveaways in public when we aren't trying to be Open Carry at all.
I will say that any belt that is seen hanging from the vendors hook ready to buy that is straight as an arrow is one that is NOT designed for the human body. Those belts are selling to flat abbed young males who's body style only exists for a few short years. The belt curved to fit over the hips ergonomically is the one to look for, and they are few and far between. They still won't fix the issue of trying to hold up a pair of pants on a tapering funnel pointing at our ankles.
Them's the breaks, a lighter or different belt may not be the answer at all. Switching to a different kind of carry may be the necessary answer, and plenty do. We may want to carry the gun, but we don't have to do it like a professional LEO/MIL or 3Gun competitor either. And that's why a lot of people didn't belt carry thirty years ago - it just didn't work for them either. Only recently have we had "experts" insisting it's the only proper way.
