Smith & Wesson M&P 4-4.625" M2.0 & X300U Inside Waistband Holster

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

This Inside Waistband (IWB) Taco Style Holster is designed for Smith & Wesson M&P M2.0 pistols (4"–4.625" 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 directly to the mounted Surefire light, not the pistol itself. This means it cannot be used without the light attached.

Precision Fit & Build Quality

• Vacuum-formed with precision-machined molds created from CAD models of the actual firearm.
• Each holster is trimmed, folded, and hand-finished in-house.
• Final fit and retention are tested with the pistol/light combination.
• Adjustable retention allows users to fine-tune the draw.
• Made from .093" thermoplastic for long-lasting durability.

Red Dot Compatibility

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

• Full sweat guard for comfort
