All you need is a dremel to cut and sand, and some redneck. It sounds like you have everything you need to make this happen. All of mine are made for 2" gun belts but the clasp will adjust for 1" belts I think.
I've got kydex holsters made for 1" lights. You really just need to take one that's already made and cut out what you don't want, sand for smooth lines, epoxy magnets and you're done.
Or design you one made out of billet aluminum and shine like a baller.
Those are $26 off Etsy. Just gotta modify it.
