Glock 43X & 48 MOS with XC3 Sub OWB Holster

Glock 43X MOS, 48 MOS, 43X & 48 and SureFire XC3 Sub OWB Outside Waistband Holster

Designed for everyday carry, range training, and open carry, this light-bearing OWB holster is precision molded for the Glock 43X MOS, Glock 48 MOS, Glock 43X, and Glock 48 equipped with the SureFire XC3 Sub weapon light. Constructed from durable .093" Kydex, this optics-ready holster delivers adjustable retention, a smooth draw, and the dependable performance expected from a purpose-built outside waistband holster.

Important: Retention is engineered around the mounted weapon light—not the firearm. The SureFire XC3 Sub must remain attached to the handgun for the holster to retain the firearm correctly.

Light Installation: This holster is designed and tested with the SureFire XC3 Sub installed using the (A) Rail Set with the #1 Key. This mounting hardware is included with the XC3 Sub by SureFire.

Precision Fit & Performance

Every Four Brothers Holster is vacuum formed using a precision-machined mold developed from CAD models of the actual firearm and weapon light. Each holster is formed, trimmed, folded, and assembled in-house before being individually tested with the actual Glock and SureFire XC3 Sub combination to verify proper fit, retention, and consistent performance.

The adjustable retention system allows you to fine-tune the draw to your preference while maintaining a secure fit for everyday carry, range use, or training.
