Safariland Model 6354RDS ALS Tactical Holster for Glock 17 MOS w/ Light, Black, R/H,

The 6354RDS holster is specifically designed for firearms with red dot sights mounted to them. This model features the Automatic Locking System (ALS), an internal locking device that retains the weapon in all directions providing secure retention in an open-top holster for tactical use. With ALS, once the weapon is holstered, it locks into place, providing an extra measure of security for the weapon. Further, the holster is completely operable with the thumb, making it very instinctive to use. And finally, once the device is de-activated a simple straight up draw can be used. Key to comfort and stability are the lightweight double leg strap and the leg shroud. SafariSuede lining helps protect the gun's sights and finish.
