The Model 6378USN is a concealment version of the all new Automatic Locking System (ALS) series holster. Once the weapon is holstered, it locks into place, providing an extra measure of security from the standard open top holsters. A simple straight draw is possible once the ALS is deactivated by your thumb while obtaining shooting grip. IDPA approved. The Model 6378USN features an all new injection molded paddle design that is highly concealable and rides close to the body with a slightly forward weapon cant. Additionally it features suede lining to help protect the gun’s sights and finish. Its SafariLaminate structure with wraparound design provides the strongest design combination.
