This open top holster features the Automatic Locking System (ALS), an internal locking device that retains the weapon in all directions with no straps or snaps to manipulate. Once the weapon is holstered, it locks into place. The holster is completely operable with the thumb and once the ALS is de-activated a simple straight up draw is used. Features a mid-ride belt loop that rides close to the body, and a suede lining to protect the gun’s sights and finish.
