Both my daughter and I use Pioneer lifting belts and I’m thrilled with the quality. Due to that experience, I was thrilled to see that they offer a gun belt.
Their Heavy Duty Gun/Work Belt has a 1.5″ width and uses the same tough sole leather they use in their lifting belts. The leather used is 5-5.5mm thick so it should have the rigidity necessary to comfortably carry plenty of weight.
This belt also features the Pioneer Cut, a series of closely spaced offset holes, for which they are known. This allows for finer adjustability by placing more holes in the same space while still leaving plenty of leather between the holes for strength.
This looks like a lot of belt for the $32 asking price.
