Glock 17/47 with Surefire X300 OWB Holster

Description

Outside Waistband Holster for Glock 17 and 47 with Surefire X300U or X300T

This Outside Waistband (OWB) taco-style holster is purpose-built for the Glock 17 and Glock 47 equipped with the SureFire X300U-A, X300U-B, X300T-A, or X300T-B weapon-mounted light. Retention is secured on the light body—not the pistol—so the holster must be used with the light mounted on the firearm.

Firearm & Generation Compatibility

Select the correct Glock generation for optimal fit: Glock 17 Gen 5, Gen 6 or Gen V, Glock 47 Gen 5, or Glock 17 Gen 3/4.

The holster is designed to fit the following pistols with additional muzzle length extending beyond the slide on shorter models, as long as the Surefire X300U or X300T is mounted correctly:

Glock 19 & 45 (Gen 5)
Glock 19 & 23, and 22 (Gen 3 or Gen 4)
This holster is not compatible with the Glock 23 Gen 5.

Surefire X300U-B Light Information & Purchase

For technical details on the Surefire X300U-B weapon light, visit the official Surefire X300U-B information page .

Our preferred light for this holster is the Surefire X300U-B, available directly from us at Surefire X300U-B Weapon Light – Four Brothers Holsters .

Precision Fit & Build Quality

Our OWB holsters are vacuum-formed using a precision-machined mold designed from a CAD model of the actual firearm and light. Each holster is formed, trimmed, and finished in-house. Final fit and function tests are done using the specific Glock and Surefire X300U combination to confirm secure retention and a consistent draw.

Retention is easily adjustable via the hardware so you can set the draw tension to your personal preference.

Threaded Barrel & Compensator Compatibility

The holster accommodates threaded barrels and compensators that are no larger than the slide in height and width. Compensators extending beyond the slide will protrude from the open muzzle end of the holster.
