I wear one of my three nearly every day, and don't get any "v-notches" at the loops, and they hold up quite nicely.
The construction of a true gun-belt is an eye-opener compared to even the best/stiffest off-the-rack belts. The support they offer to your gear is incredible, and they (at least for me) ended the movement of a holster and the backache that can come with carrying a full-sized weapon and backup mags. Balancing the weight on your belt helps a ton too. If I carry just the pistol, my lower back doesn't feel so hot after a day on my feet--if I put the pistol on one side, and a pair of mags on the other, I can be on my feet all day without noticing anything.
Any of the quality gun-belt manufacturer's products are great. Galco, BeltMan, Comp-Tac, Bianchi, 5.11, Wilderness, all make good quality belts that will make a huge difference for you.
To my knowledge, all of Wilderness' belts are nylon "boy-scout/GI) style, and 5.11 offers both leather and nylon. The rest of the manufacturers I mention make mostly leather products.
The 5.11 series of leather belts are a great starting point if you don't want to drop upwards of $75-100 on a gun belt as a first try. Many surplus stores carry the leather series, and locally (in Houston) I've been able to find them in the $35 range -- in the price range of a good dress belt.
The only problem with most gun belts is their width -- most gear, and most belts, are setup for 1.5" loops/slots these days--it's a great standard, and it works perfectly with jeans, and "kahkis" in my experience...my good suits, not so much--won't go through the loops. I keep meaning to either have a custom 1.25" belt made, or to have a tailor fashion me some belt loops that will support the 1.5" belts I prefer...just haven't gotten it done yet.
And since I haven't seen it mentioned here yet (and it seems that you already are aware of this) -- the belt is the foundation of any carry system. I would rather carry a $5 holster on a good belt than carry a top-of-the-line holster on a belt that won't support the rest of the rig.
As for JALLEN, I think you may have identified a cross-platform/cross-manufacturer design flaw there--my belts seem to be shorter some days than others too...what's up with that?
