Smith & Wesson M&P 5.6" 10MM M2.0 & X300 Inside Waistband Holster

Inside Waistband Holster for Smith & Wesson M&P 10MM Performance Center 5.6" with Surefire X300

This Inside Waistband (IWB) Taco Style Holster is designed to fit the Smith & Wesson M&P 10MM Performance Center M2.0 5.6" pistol, with or without thumb safety. It is built for use 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 will not work without the light attached. One customer has also confirmed compatibility with the Surefire X300 Vampire, though this is not factory-tested.

Precision Fit & Craftsmanship

• Vacuum-formed using precision CAD-based molds of the firearm.
• Individually formed, trimmed, and finished in-house.
• Each holster is test-fitted with the actual pistol and light combination.
• User-adjustable retention for preferred 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 and smooth edges for comfort
• Made from .093" thermoplastic for long-lasting durability
• Available in right- and left-handed configurations
• Proudly made in the USA
