The GBRS Group Xpriority 1 OWB holster is a duty-ready outside-the-waistband rig built for shooters running a Glock with a SureFire X300U weapon light. This is serious carry gear born from GBRS collaboration with Priority 1—the kind of holster that lives on a duty belt or range setup where you need fast access, rock-solid retention, and room to grow your setup. If you're carrying optics, running a threaded barrel, or planning upgrades down the line, this holster is engineered to keep pace.
Built from 0.93" Boltaron polymer, the Xpriority 1 gives you the durability and retention control real-world users demand. The paddle attachment comes standard, but the modular design plays well with drop-leg and belt-mounted systems—especially when paired with True North Concepts Modular Holster Adapters for maximum flexibility. Retention is user-adjustable via screw mechanism, so you dial in the draw feel that works for your workflow, whether that's competition practice or duty rotation.
Open-muzzle design means you're not locked into one barrel length: suppressor-height sights, threaded barrels, and compensators all fit without modification. The holster also ships optics-cut ready, so most modern slide-mounted red dots are accommodation-ready out of the box. One critical note: this holster is built specifically for the SureFire X300U-A and X300U-B—it will not function with other light brands or models, so verify your weaponlight before ordering.
