Right now, my two favorite holsters for it are the Blade Tech IWB, which is a kydex holster, and the Milt Sparks Versa Max II, which is also a IWB holster, but in leather.
I also have a couple of Desantis OWB holsters which are also leather and work well, if you prefer the holster on your belt outside your pants.
