The retention system locks directly onto the mounted weapon light rather than the pistol frame, creating a precise and consistent draw. Because the retention indexes on the light, the holster will not function without the compatible SureFire X300 light installed.

Each holster is CAD-designed for precision and vacuum-formed from durable .093" thermoplastic. Every unit is hand-finished to ensure consistent fit, smooth edges, and long-term durability. Adjustable retention hardware allows you to fine-tune draw resistance to your personal preference.

The contoured profile supports stable carry while minimizing bulk for improved comfort throughout the day. You can also explore different IWB holster belt attachment options to configure the carry position that best fits your concealed carry setup.

If you need a compatible weapon light, the holster is designed to work with the SureFire X300U-B weapon light, one of the most trusted lights for duty and concealed carry pistols.

You can also personalize your holster by selecting from multiple Kydex patterns and finishes using our Kydex holster color guide.
