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

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

This Inside Waistband (IWB) Taco Style Holster is designed to fit the Smith & Wesson M&P 10MM M2.0 pistol, available in 4" and 4.6" barrel lengths, with or without thumb safety. It is compatible with the Surefire X300U-A, X300U-B, X300T-A, and X300T-B weapon-mounted lights.

Light-Based Retention System

The holster secures on the mounted Surefire light—not the pistol itself. It cannot be used without the light attached.

Precision Fit & Craftsmanship

• Vacuum-formed using precision CAD-based molds of the firearm.
• Individually formed, trimmed, and finished in-house.
• Each holster is fit-tested with the actual pistol and light combination.
• User-adjustable retention for custom draw tension.

Optics & Sight Compatibility

The holster profile is cut to clear most red dot sights, including optics that overhang the side of the slide.

Key Features

• Full sweat guard
• Adjustable retention
• Minimal material with smooth edges for comfort
• Made from .093" black thermoplastic for durability
• Proudly made in the USA
