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 745BL belt clip for 1.5 in. (38 mm) to 2.25 in. (58 mm) belt widths.
