I have a Pocket Companion XL kydex pocket holster from David Stillwell at Grandfather Oak Holsters ( http://www.grandfatheroak.com/Stockdesigns.html ) for my Kahr PM9 9mm. It's a nice holster that conceals well as long as you wear pants that are on the baggy side with sturdy pockets.

I also have one of Eric Larsen's leather pocket holsters for a S&W J-Frame-sized five-shot revolver. I pressed it into service with my Taurus 905 9mm revolver
