Rigel is the brightest star in the constellation Orion and our WML IWB/AIWB holster. Our Rigel shares all of the standard features of the Orion AIWB holster, but in a weapon mounted light holster. It is compatible with the Streamlight TLR-1 HL. TLR-1, and TLR-1S. For IWB and AIWB specifically the length is driven by the attached light. For that reason we make the Rigel compatible with all Glock 9/40 double stack models and round off the muzzle. When worn in the AIWB position with a 19/17 length pistol the extra holster merely occupies empty space.
