XPRIORITY 1 IWB HOLSTER RH FOR SIG P320 W/X300U BLACK
$94.99
The Gbrs Group x Priority 1 IWB holster for SIG P320 with SureFire X300U is built for shooters who demand a concealed carry rig that handles modern kit without compromise. This right-hand inside-the-waistband holster marries precision engineering with practical carry features—optics-ready, light-compatible, and trimmed to work with threaded barrels. If you're running a P320 with a mounted optic and a weapon light, this holster is designed to accommodate both while keeping your grip secure and your profile low.
Gbrs Group precision-forms the holster from 0.080-inch Boltaron, a proven thermoplastic that resists sweat and wear while staying lightweight. Every unit is CNC-trimmed, hand-finished, individually test-fit, and inspected—no shortcuts. The design philosophy is straightforward: retention you can adjust, carry angles you can dial in, and features that actually reduce printing. That includes a full sweat guard to keep the rear sight off your body, a concealment wing to rotate the grip inboard, and a Discreet Carry monoblock belt clip that works with or without a belt.
Cant is adjustable to 0 or 15 degrees, and ride height adjusts when you swap between tuckable and standard attachments. The open muzzle accepts threaded barrels and most compensators. An optics channel is molded and trimmed to fit common slide-mounted red dots. This isn't a universal holster—it's purpose-built for the P320 and the X300U light, which means fit is tight and function is predictable. If you're carrying a modern duty or competition gun with modern accessories, this holster speaks your language.
