Smith & Wesson M&P 4" & 4.6" 10MM M2.0 & X300U Outside Waistband Holster

Outside Waistband Taco Holster for Smith & Wesson M&P 10MM M2.0 with Surefire X300

This OWB Taco Style Holster is designed for the Smith & Wesson M&P 10MM M2.0 pistol with thumb safety, paired with the Surefire X300U-A, X300U-B, X300T-A, or X300T-B weapon-mounted light.

Light-Based Retention System

The holster retention is on the mounted Surefire light, not the pistol frame, meaning it will not work without the light attached.

Compatible with the 4" and 4.6" barrel lengths, with or without the thumb safety, as long as the Surefire X300 is attached.

Each holster’s fit and function are verified using the actual 4.6" pistol with thumb safety and Surefire X300 before packaging and shipment.

• Vacuum-formed with precision CAD-based molds of the firearm.
• Formed, trimmed, folded, and finished in-house.
