The Gbrs Group X Priority 1 OWB holster for the Sig Sauer P320 with SureFire X300U is a purpose-built rig that bridges practical duty ergonomics with the modularity serious shooters demand. Gbrs Group partnered with Priority 1 to create a holster that handles everything from range sessions to varied carry setups, all without compromising retention or accessibility. Built from 0.93" Boltaron — a thermoplastic engineered for durability and weight efficiency — this outside-the-waistband holster is right-hand draw and designed specifically around the P320 paired with a SureFire X300U-A or X300U-B mounted light. That light-specific design means the holster fits the gun-and-light combo exactly, not as an afterthought.
What makes this holster stand out on the range and in practical use is its flexibility. The open-muzzle design accommodates threaded barrels and compensators, so you're not locked into a single setup. The holster is cut and ready for most common slide-mounted optics — standard or suppressor-height sights work too. Retention is user-adjustable via a screw-on mechanism, so you can dial in exactly how much resistance you want for your draw. The paddle attachment comes included, and because it's part of Gbrs' modular ecosystem, you can pair it with True North Concepts adapters for belt or drop-leg mounting options if you want to experiment beyond the standard ride.
This is a straightforward, no-nonsense choice for P320 shooters who run a light and value the ability to tune their holster to their preference rather than being stuck with a one-size-fits-nobody retention feel. If you're planning to use this setup with an accessory light, verify you have the SureFire X300U-A or X300U-B — other light brands and models are not compatible.
