This open top tactical holster features the Automatic Locking System (ALS®). Once the weapon is holstered, it locks into place. When the ALS is de-activated by the thumb, a simple straight up draw is used. It features the single strap leg shroud allowing the holster to be worn higher on the thigh and a vertical leg strap with quick-release detachable leg harness. This model is constructed of the innovative SafariSeven™ material, a high performance nylon blend. SafariSeven™ is highly durable and practically impervious to the elements.
