I have had a Belman belt for over 15 years now and could not be happier. I catty a full size 1911 in a Milt Sparks holster almost daily. I picked the horse hide 1.5". It still looks like new. No need for the added stiffener layer. Comfortable! I've tried numerous belts and this is the best I've found. Ordering a new one soon in 1.5" Elephant.
Bullhide CCW Gun Belts for Concealed and Open Carry by Beltman
I also have a Beltman (though not quite as old as yours) that has held up admirably. I also have a Bigfoot gunbelt. I have looked at the belts the OP has, but I'm a fan of leather.
