Glock 20 & X300U Duty & Competition Holster

Glock 20 w/ Surefire X300U-A/B – Duty & Competition Holster

Designed for those who demand more from their gear, this holster is built to support the full-sized firepower of the Glock 20 paired with the Surefire X300U-A or B. Whether you're running drills, working a shift, or stepping onto the competition line, this single-level retention rig brings purpose-built performance to every draw.

Made from rugged Kydex and engineered for secure lock-up and consistent access, our duty/competition setup features open-bottom clearance, optimized sight channels, and precision-molded fitment for both the A and B variants of the X300U.

Built for Performance:

Fits Glock 20 with Surefire X300U-A or X300U-B

Compatible with red dot optics and suppressor-height sights

Adjustable retention for a consistent, confident draw

Open muzzle for threaded barrels or compensators

Works with popular competition and duty belt mounting platforms (Safariland, G-Code, Blade-Tech, True North Concepts, and more)

Why It Stands Out:

Tuned for high-stress performance

Molded from CAD-based files using the actual weapon/light combo

Ideal for 3-Gun, USPSA, light tactical duty, or armed professional applications

Hand-assembled and tested in the USA

If you're running 10mm with the X300U, you're not messing around—this holster keeps that same energy.
