The Safariland 6304 ALS/SLS Tactical Holster is designed to ensure the maximum safety your firearm. The ALS (Automatic Locking System) secures the firearm upon holstering, while the SLS (Self Locking System) clicks into place for additional safety. Both mechanisms release quickly to allow a smooth, efficient draw when every second counts. Constructed from thermoformed SafariLaminate, the 6304/6305 holster handles harsh environments, and the soft suede lining and molded sight track protect your firearm’s finish and sights. The wide shroud and dual elastic straps add comfort and stability, and silicone grip strips help eliminate movement. Mounting holes on the shroud accept ELS, QLS and MLS accessories, making the 6304 ideal for gear-heavy roles.
