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.
