The Safariland 6390RDS Holster (brand part no. 6390RDS2832132) is specifically designed for the Glock 19 MOS mounting a red dot sight, paired here with a Surefire X300U weapon light. The Safariland holster’s open-top design uses the Automatic Locking System (ALS), an internal locking device that retains the weapon in every direction with no straps or snaps to manipulate. Once holstered, the pistol locks into place automatically, and the ALS is deactivated and operated entirely with the thumb during the draw. It is built for a left-hand draw and finished in black STX for duty and competition use with an optic-and-light-equipped Glock 19.
