Glock 43X & 48 MOS with TLR-7 Sub IWB Holster

Glock 43X MOS, 48 MOS, 43X Rail & 48 Rail and Streamlight TLR-7 Sub IWB Inside Waistband Holster

Designed for concealed carry, this Glock 43X MOS, 48 MOS, 43X Rail & 48 Rail and Streamlight TLR-7 Sub IWB Inside Waistband Holster is precision molded for pistols equipped with the Streamlight GL version of the TLR-7 Sub weapon light. Built from durable .093" Kydex, this optics-ready holster offers adjustable retention, adjustable ride height and cant, and a slim profile that helps minimize printing while providing a consistent draw for everyday carry.

Important: Retention is engineered around the mounted weapon light—not the firearm. The Streamlight TLR-7 Sub must remain attached to the handgun for the holster to retain the firearm correctly.

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 Streamlight TLR-7 Sub combination to verify proper fit, retention, and reliable performance.

The adjustable retention system allows you to fine-tune the draw to your preference, while adjustable ride height and cant let you customize the holster for appendix carry or other preferred concealed carry positions.
