It features the ALS (Automatic Locking System) retention, an internal locking device that secures the firearm in all directions simply upon reholstering. This ergonomic design features a straight-up draw and the release is completely operable with the thumb, making it very instinctive to use. The 7378RDS holster has an open-top design without SLS for quick retrieval of firearm. This model is constructed of the innovative SafariSeven material, a high performance nylon blend. SafariSeven is highly durable and practically impervious to the elements.
