Safariland 6378 ALS Holster Glock 20/21 w/ X300 Paddle Mount RH

The Safariland 6378 ALS holster delivers automatic weapon retention and rapid deployment for Glock 20/21 pistols equipped with Surefire X300 weapon lights. This outside-the-waistband holster combines Safariland's proven Automatic Locking System with durable SafariLaminate construction for professional and civilian use.

What Makes This Different

The Automatic Locking System (ALS) secures the firearm upon holstering and releases with a natural straight-up draw motion using the thumb. Unlike traditional retention holsters that require multiple steps or awkward hand positions, the ALS allows for instinctive operation under stress. The SafariLaminate construction provides the rigidity of Kydex with enhanced scratch resistance and quieter operation.

Key Features

• Automatic Locking System (ALS) provides Level II retention without manual manipulation
• SafariLaminate construction resists scratches and reduces operational noise
• Specifically molded for Glock 20/21 with Surefire X300 weapon light
• Paddle mount design allows easy on/off without belt removal
• Suede lining protects firearm finish during holstering and drawing
• Open-top design accommodates various sight configurations
• Right-hand configuration with adjustable cant angle

Field testing demonstrates consistent lock-up and smooth draws across temperature ranges from -20°F to 120°F. The paddle mount distributes weight evenly across the waistband, reducing printing and improving comfort during extended wear. Law enforcement agencies and competitive shooters rely on this holster design for duty carry and USPSA/IDPA competition where equipment reliability determines performance outcomes.
