Safariland 6390Rdso2832131 Als Black Fits Glock 19 Mos Compatible W/ Surefire X300U Right Hand

The Safariland 6390RDS is a purpose-built OWB (outside-the-waistband) holster engineered for Glock 19 MOS pistols equipped with the SureFire X300U tactical light. This is the right-hand draw version in black, designed for shooters who run a weaponlight on their duty or personal-defense Glock and need a retention system that keeps up with serious use—whether that's patrol, range work, or defensive carry. Safariland's ALS (Automatic Locking System) is the standout here: it secures your pistol automatically as it enters the holster, then releases with an intuitive thumb lever during the draw. You get active retention without fumbling.

The 6390RDS is built to tolerate real-world handling. The holster body is injection-molded for durability and consistency, and the design accommodates the MOS (Modular Optic System) mounting cuts on your slide—no workarounds needed. Fit is tight to the Glock 19 and the X300U, so you won't experience unwanted play or shift during movement or draw practice. The SureFire X300U pairing is explicit, so verify your light model before ordering if you're uncertain.

Right-hand draw means the holster is angled for natural access from your dominant side, typical for belt carry at the 3 o'clock position. This is a working holster, not a lifestyle accessory—expect to deploy it in training and carry regularly if you choose it. Safariland's reputation for retention and durability backs the 6390RDS, making it a solid choice for shooters who want one less thing to worry about when seconds matter.

Frequently Asked Questions

Will this holster fit my Glock 19 without the MOS cuts?

No. This holster is molded specifically for the Glock 19 MOS. Standard Glock 19 slides without optics cuts will not fit properly.

Can I use this holster with a different weapon light?

This holster is designed for the SureFire X300U. Using a different light model may result in poor fit or retention issues. Stick with the X300U or check with Safariland for compatible alternatives.

Is the ALS thumb lever easy to operate during a draw?

The ALS thumb lever is designed for intuitive, under-stress operation. With practice, the motion becomes reflexive—your thumb naturally sweeps the lever as you grip and draw. Range time is essential to build that muscle memory.

What carry position is this holster designed for?

The 6390RDS is a right-hand OWB holster angled for typical belt carry at the 3 o'clock position on your strong side. Exact positioning depends on your body mechanics and belt setup.
