Sig Sauer P320-XTEN & X300U Align Tactical Thumb Rest OWB Holster
Our Outside Waistband Taco Style holster for the Sig Sauer P320-XTEN 10MM pistol with the Surefire X300U-A or X300U-B and the Align Tactical Thumb Rest is vacuum formed with a precision machined mold designed from a CAD model of the actual firearm and light.
Each holster is formed, trimmed, and folded in-house. Final fit and function tests are done with the actual pistol and light to ensure the holster fits the gun/light combination and has the correct amount of retention. The retention of the holster is easily adjusted so that the fit can be dialed into your personal preference.
This holster will NOT work properly without the X-300 mounted to the pistol, the retention is on the light itself and not the firearm.
The profile of the holster is cut to clear the Sig Romeo 1 Pro as well as many other Red Dot Sights.
This holster does work with the X300 Turbo light mounted on the XTEN.
- Full Sweatguard
- Adjustable retention
- Made from .080" thick thermoplastic for durability
- Open Muzzle for threaded barrels or compensators
- Minimal material and smooth edges to reduce printing.
- The holster is designed to accommodate a red dot sight mounted to the pistol
- Proudly made in the USA.
9mm for the hoods, 10MM for the woods!
