I just bought two 1 1/2" leather belts from Sportsman's Guide...2 prong, holes all the way around. One brown, one black for a total price of about $18 for the pair + shipping. They arrived 2 weeks ago. Excellent quality for the price. Plenty hefty enough for holster carrying...IWB or OWB.
sportsmanguide.com Search for belts.
I do not work for SG. Just thought you guys would be interested.
