GBRS Group Priority 1 SIG P320 X300U RH IWB Holster

The GBRS Group x Priority 1 IWB Holster is a right-handed inside-the-waistband design fitted for SIG P320 with a SureFire X300U. Its rigid Boltaron shell uses adjustable retention so draw tension can be tuned instead of being locked to a fixed setting. The black holster also uses an optics-ready cut and an open-ended muzzle area that can accommodate common slide-mounted optics and threaded-barrel configurations when the pistol fit allows.

The GBRS Group Priority 1 SIG P320 X300U RH IWB Holster includes adjustable cant and ride height, giving the user room to change how the pistol sits inside the waistband. A full sweat guard separates the rear of the slide from the body, while the concealment wing helps rotate the grip inward to reduce printing. The Discreet Carry MONOBLOCK clip is designed to hold the holster securely with or without a traditional belt.

Fit should be verified against the exact SIG P320 configuration before carry, particularly on this light-bearing version. A holster is a fit-specific item, so firearm model, mounted light, hand orientation, and optic clearance matter more than appearance alone.
