The Gbrs Group Xpriority 1 OWB holster is a serious outside-the-waistband option built for shooters running a Glock with a SureFire X300U weaponlight. This is purpose-built gear designed around real-world use—whether you're working through drills at the range or training for duty carry. Gbrs Group collaborated with Priority 1 to create a holster that balances retention, accessibility, and modularity without the bloat.
Built from precision-molded Boltaron polymer, the Xpriority 1 delivers durability in a lightweight package. The open-ended muzzle design accommodates threaded barrels and compensators, so your setup isn't locked into factory specs. Adjustable screw-on retention lets you dial in the resistance you want—tighter for dynamic work, lighter for speed shooting. The paddle attachment comes standard, but this holster plays well with modular belt and drop-leg mounting systems if you want to experiment with different carry positions.
One critical note: this holster is engineered specifically for the SureFire X300U-A and X300U-B lights. It won't accept other light brands or models. If you're running a different weaponlight, this isn't your solution. The optic cut is already built in to accommodate most common slide-mounted optics, and the design clears suppressor-height sights without issue.
