I have an ISWB leather / kydex hybrid holster for my LCR 2 inch as well as an OWB holster and pocket holster.

What I want is a smaller ISWB holster. Something with a smaller "footprint" against my skin than the hybrid holster. Something I can really sweat on in Florida.

That probably means entirely Kydex.

Perhaps a holster maker produces this style for both J-Frames and Rugers. Anyone?
