Frequently Asked Questions

How does the ALS retention system work on the Safariland 6378?

The Automatic Locking System (ALS) automatically locks the firearm in place the moment it is seated in the holster — no manual snapping or toggling required. To draw, the shooter sweeps their thumb naturally across the release lever positioned at the rear of the holster, disengaging the lock for a smooth, uninhibited draw. This makes the ALS system exceptionally fast while maintaining a high level of security against weapon grabs.

Will this holster fit a Glock 17 with a light or optic attached?

The Safariland 6378 is precision-molded specifically for the standard Glock 17 without a weapon-mounted light or optic. If your Glock 17 is equipped with a rail-mounted light such as the Streamlight TLR-1 or SureFire X300, you will need a light-bearing variant of the 6378 or a compatible Safariland model designed for that light/firearm combination. Optic-cut compatibility varies by model revision — contact Goodland Guns for guidance on the best fit for your setup.

What mounting options are compatible with the Safariland 6378 ALS?

The 6378 ALS is designed to integrate with Safariland's versatile mounting ecosystem, including the Mid-Ride UBL (Universal Belt Loop) and the Quick Locking System (QLS). This allows you to swap the holster between multiple platforms — from standard duty belts to drop-leg and MOLLE configurations — without needing additional tools. The modular system makes the 6378 a highly adaptable choice for both duty and range use.
