Description
The Safariland 6390 ALS is a mid-ride duty holster built for the Glock 17. It’s designed for uniformed security, law enforcement, and serious shooters who require a secure, fast, and reliable retention system. We’ve stocked this model since early 2026, and it’s one of our most consistent repeat-seller holsters for duty use. The primary benefit is the proven Automatic Locking System (ALS) that secures the firearm until intentionally released.
Key Highlights
- Automatic Locking System (ALS): Internally locks the firearm into the holster upon full insertion. Release is intuitive with the thumb.
- Level I Retention: Meets common security standards for duty and professional use.
- Mid-Ride Height: Balances accessibility and security, compatible with standard duty belts.
- Durable Construction: Molded from Safariland’s proprietary polymer for consistent performance.
- Passive Hood Guard: Helps protect the rear sight from damage during daily use.

What Buyers Ask
Will this holster fit a Glock 17 with a weapon-mounted light?
No. The Safariland 6390 is designed for a standard Glock 17 without a light attachment. You would need a specific Safariland model, like the 6390RDS for lights, which has a different shell.
Is the retention adjustable?
The ALS system’s retention tension is not user-adjustable. It is set at the factory for a consistent, secure draw. The system is designed to function reliably without needing adjustment over time.
Does it work with a Glock 19?
It can, but it is not optimal. The 6390 is molded specifically for the full-size Glock 17/22 frame. A Glock 19 will fit and the ALS will lock, but there will be extra space at the muzzle end, which some users find less secure for active duty.
