If you want a leather belt you can go to any of the big name holster makers and they all make fine belts.
Or, you can order a belt designed to carry a gun, made of leather from a man that makes nothing but belts. Google "The Belt Man" if that's what you are looking for. He's located in Apex, NC, if that helps.
I wear one of his "Dress Belts" when I'm in a brown or taupe shade of suit, otherwise it's my black Mitch Rosen belt in a suit. When I'm in "casual" or more "normal" clothes I wear a Ted Blocker or a Bruce Gibson Belt. I'm going to add a Mark Garrity Belt soon, along with a holster
Having a good belt, designed to support a firearm is the secret to successful concealed carry IMO. Psst, I carry and N-Frame Revolver if that's any sort of a clue. Of course, a well designed holster helps too.
