I love my Kore essentials belt. It uses a ratcheting system and is easily adjusted between sitting and standing.
I really like my Hanks belt. It’s very comfortable.
Those are the only two gun belts I have experience with other than an $11 Amazon buy (hint: don’t get that one).
There are lots of good brands. A good belt makes a huge difference. They are worth every penny. A good gun belt will hold its shape like a hula hoop when you hold it up .
