Aspen International: Safariland ALS Training Video

Automatic Locking System (ALS™)
The ALS™ system is the next evolution in retention holsters and builds upon the successful SELF LOCKING SYSTEM (SLS). With many patents to its credit, the key to this system is an internal locking device that secures the weapon in all directions simply upon re-holstering, providing Level II Plus Retention™ which can also be elevated to Level III Plus Retention™ with the addition of the Sentry. Additionally, holsters with this all-new ergonomic design are completely operable with the thumb making training easy, and the straight up draw makes them very instinctive to use, yet difficult for an assailant's attempted takeaway. Watch the movie to see the holster system in use.
