Outside Waistband Duty & Competition Holster for Smith & Wesson M&P 10MM M2.0 with Surefire X300
This Duty & Competition Style OWB Holster is designed for the Smith & Wesson M&P 10MM M2.0 (4" and 4.6" barrels), with or without thumb safety, when paired with the Surefire X300U-A, X300U-B, X300T-A, or X300T-B weapon-mounted light.
Light-Based Retention System
The holster secures on the mounted Surefire light—not the pistol frame—so it will not work without the light attached.
