This model is constructed of the innovative SafariSeven™ material, a unique nylon blend from DuPont™. SafariSeven™ is highly durable and practically impervious to the elements. This 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 comes standard with the UBL Mid-ride, fitting 2 in. to 2.25 in. belt widths.
