Glock 43X & 48 MOS with XC3 Sub Duty & Competition Holster

Glock 43X MOS, 48 MOS, 43X Rail & 48 Rail and SureFire XC3 Sub OWB Outside Waistband Light Duty & Competition Holster

Built for competitive shooting, range training, and everyday OWB carry, this light-bearing OWB holster is precision molded for the Glock 43X MOS, Glock 48 MOS, Glock 43X Rail, and Glock 48 Rail equipped with the SureFire XC3 Sub weapon light. Constructed from durable .093" Kydex, the optics-ready design delivers adjustable retention and a fast, consistent draw for dependable performance on the range or during competition.

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, consistent retention, and reliable performance.

The adjustable retention system allows you to fine-tune the draw to your preference while maintaining a secure fit during competition, training, and light-duty use.
