Would something like this 5.11 Operator belt work for concealed carry?
I use a 5.11 Trainer Belt which is the same as the Operator just .25 narrower. I’ve been using it for a couple of years and have been pleased with the performance and quality. I like the adjustment of the belt as you can easily compensate when changing holsters or other gear.
Just be sure to allow for the extra length required for your holster and any other gear when specifying length. Also, make sure the belt is not too wide to fit you holster and or belt loops on your pants.
