Safariland
The Safariland 6378RDS is a purpose-built holster for shooters carrying a Glock 19 MOS (Modular Optic System) with a mounted SureFire X300U tactical light. This right-hand draw holster combines Safariland's proven ALS (Automatic Locking System) with the practical needs of armed professionals and serious civilian shooters who've upgraded their pistol with modern optics and weapon lights. If you're running a micro red dot and a dedicated light on your G19 MOS, this holster is engineered to secure that specific setup—no compromises.
The ALS mechanism locks your pistol in place the moment it holsters, relying on a positive thumb-activated release rather than friction or retention straps. That design keeps your firearm secure during movement and physical activity while allowing a clean, intuitive draw when you need it. The holster accommodates Glock 19 Gen 3 and Gen 4 frames, so if you've been running either generation, you're covered. Safariland's engineering ensures the X300U sits flush with the holster body—no light snag, no awkward presentation.
Built for duty and training, this is the kind of holster you see on duty belts and at serious shooting schools. It won't coddle your pistol, but it will hold it securely and let you access it when it matters.
