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.
