The collaboration between Haley Strategic Partners (HSP) and G-Code has produced the INCOG Shadow Holster. This is a weaponlight capable IWB holster which should be convenient for those who prefer a weaponlight mounted beneath their pistol rails all the time. You can select between a single and dual-cip system. Compatible with Mag Caddy it is available for the Glock 19, Glock 18, H&K VP9, 4.5" SMith & Wesson M&P in 9mm and .40 S&W that use the Surefire X300 or X300 Ultra.
