Vanguard - Light Compatible Holster Gun Fit: SureFire X300 Ultra A/B (Tuckable Over Hook Strut 1.5 and 1.75 included). The VanGuard (VG3) is minimalist IWB holster designed to be used with weapon mounted lights. Unlike traditional IWB holsters, the VG3 attaches to your weapon light and covers only the light and trigger guard of your weapon. This unique design eliminates the bulk of traditional holster, while providing level of safety and security not attainable by simply sticking pistol in the waistband of your pants. Because the holster is fitted to the light and not the weapon, the VG3 will work with wide variety of pistols. The VG3 is fully ambidextrous, tuckable, and can be worn anywhere on the waistline except the small of the back.
