This 6384 open top holster features the Automatic Locking System (ALSŪ), an internal locking device that retains the weapon in all directions with no snaps or straps to manipulate. This holster is optimized for use with a MOLLE vest. Key to comfort and stability are the double leg strap and leg shroud. The leg harness is lightweight and simple to operate. Suede lining helps protect the gun's sights and finish.
