Glock 43X & 48 MOS Duty & Competition Holster

Glock 43X / 48 Duty & Competition OWB Holster

This outside-the-waistband (OWB) duty and competition holster is designed to fit the Glock 43X MOS, Glock 48 MOS, Glock 43X Rail, and Glock 48 Rail pistols. Built for training, competition, and range use, this holster delivers a secure fit, adjustable retention, and a fast, consistent draw.

Precision Construction & Fit

Each holster is vacuum-formed using a precision-machined mold created from a CAD model of the actual firearm. All forming, trimming, and finishing is completed in-house.

Final fit and function testing is performed using the actual pistol to ensure proper retention, smooth draw, and reliable performance.

Retention is fully adjustable, allowing you to fine-tune draw resistance to your personal preference.
