Sig Sauer P211 GTO & X300 Duty & Competition Holster

This Duty & Competition holster is built for the Sig Sauer P211 GTO with Surefire X300U-A, X300U-B, X300T-A, or X300T-B weapon-mounted light. Designed for competitive shooters and duty use, it delivers a stable platform, secure retention, and smooth draws—ready for training, range sessions, or match day performance.

Light-Based Retention System: This holster locks onto the mounted Surefire light, not the pistol frame, and cannot be used without the light attached. That design ensures consistent fit and draw, while giving you dependable security under stress.

For customers who need a compatible weapon light, we offer the SureFire X300U-B weapon light.

Every holster is precision-built using a CAD-designed mold, vacuum-formed from .093" thermoplastic, and hand finished for consistency. The adjustable retention system lets you fine-tune draw resistance, while the contoured body provides excellent stability during movement. Explore competition belt attachment options and personalize your rig by choosing the right holster color.
