The Safariland 6354RDSO Duty Holster for the Glock 17 MOS with a SureFire X300, Right Hand (Safariland part no. 6354RDSO-832-721-MS19) is a duty holster built specifically for red-dot-equipped pistols. Safariland’s Automatic Locking System (ALS) secures the pistol with a lever the thumb releases during the draw, giving duty and patrol shooters a reliable retention level beyond simple friction fit. Unlike Safariland’s standard RDS series, the RDSO variant uses an open pocket around the optic instead of a flip-up dust cover, so the red dot stays protected without an extra moving part to manage. This cut is sized for the Glock 17 MOS slide with a SureFire X300 mounted, and it’s built for right-hand draw.
