Safariland 6390RDS ALS Level I Holster Glock 19 MOS SureFire X300U

The Safariland 6390RDS ALS holster delivers secure weapon retention for Glock 19 MOS pistols equipped with SureFire X300U weaponlights. This duty-grade holster combines the proven ALS (Automatic Locking System) with red dot sight compatibility for modern tactical applications.

What Makes This Different

The 6390RDS series incorporates an open-top design that accommodates various red dot optics without requiring sight-specific modifications. Unlike standard holsters that interfere with optic housings, this model features a raised sight channel and relief cuts. The ALS mechanism engages the trigger guard automatically upon holstering, providing Level I retention without manual thumb breaks or straps.

Key Features

• ALS automatic locking system secures weapon in trigger guard area
• Red dot sight compatible with raised sight channel design
• SureFire X300U weaponlight compatible with molded light bearing capability
• SafariLaminate construction resists impact and temperature extremes
• Straight draw cant with adjustable belt loop attachment
• Open muzzle design accommodates threaded barrels and compensators
• Right-hand configuration with thumb-activated release mechanism

Field performance centers on rapid presentation while maintaining positive weapon control. The ALS system releases with natural thumb placement during the draw stroke, eliminating fumbling with retention devices under stress. The holster maintains its grip on the weapon even when inverted or subjected to impact forces. Weather-resistant SafariLaminate construction performs consistently in temperatures from -50°F to 300°F.
