The 7TS 7390RDS holster is specifically designed for firearms with red dot sights mounted to them. 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 deactivated a simple straight up draw is used. Features a mid-ride belt loop.
