Smith & Wesson M&P 10MM M2.0 4" with Surefire X300 Outside Waistband Holster
This OWB (Outside Waistband) Taco Style Holster is designed for the Smith & Wesson M&P 10mm M2.0 4" pistol paired with the Surefire X300U-A, X300U-B, X300T-A, or X300T-B weapon-mounted light. Constructed from durable .093" Kydex thermoplastic, this optics-ready holster delivers adjustable retention, a smooth draw, and the dependable performance expected from a purpose-built outside waistband holster.
This holster is designed to work on pistols with or without the thumb safety.
**Please note: Our 4BROS Belt Slides are designed to work with standard belts for everyday carry, not thicker "Battle Belt" style belts with rows of MOLLE on the outside.
