Gbrs Group
The Gbrs Group Xpriority 1 OWB holster for Glock with X300U weaponlight is a serious choice for shooters who run a light on the range or in duty carry. Built from precision-molded Boltaron polymer, this right-hand outside-the-waistband holster is engineered to work seamlessly with the SureFire X300U-A and X300U-B mounted on compatible Glock platforms. Whether you're training hard at the range or setting up a duty rig, this is a holster that earns its place in a professional shooter's kit.
The design philosophy here is modularity and adaptability. Gbrs Group and Priority 1 collaborated to create a platform that doesn't lock you into a single carry method—paddle attachment comes standard, but the holster integrates with True North Concepts modular holster adapters for belt or drop-leg mounting configurations. That flexibility matters when your needs change or when you're building a system that works across different environments. The open muzzle design is a big win if you run threaded barrels or compensators; most OWB holsters force you to choose between light mounting and muzzle options, but this one handles both.
Retention is user-adjustable via screw-on positive retention mechanism, so you can dial in exactly how secure you want your draw. The holster ships optics cut ready, meaning it's prepared to accept most slide-mounted red dots without additional modification. If you're running suppressor-height sights or other aftermarket optics solutions, this holster is built to accommodate them. One critical note: this holster is engineered specifically for the SureFire X300U-A and X300U-B—it won't function with other light brands or models, so verify your setup before ordering.
Built for shooters who take training seriously and demand consistency in their gear, the Gbrs Group Xpriority 1 delivers the durability and precision you expect from the collaboration between two names known for no-compromise design.
