Sl 6378 Als For Glk 19 Stx Hg Blk Rh

The Safariland Model 6378 ALS Paddle Holster for Glock 19/23 with 4" Barrel, Right-Hand, STX High-Gloss Black Finish is a duty-proven retention holster designed for law enforcement, security professionals, and armed civilians who demand secure firearm retention without compromising draw speed. The ALS (Automatic Locking System) secures the pistol through contact with the trigger guard the moment the weapon is holstered—no manual thumb break required—while the paddle mounting system allows rapid donning and removal from duty belts.

The STX high-gloss black finish resists corrosion and maintains appearance under regular wear, while the polymer construction keeps the holster lightweight without sacrificing durability. The ALS mechanism provides Level II retention, preventing unauthorized weapon removal during physical engagement while allowing the operator to draw under stress with a simple upward motion. This design is particularly valuable for patrol officers, security details, and field operators who face contact with subjects or require tactical repositioning during duty.

Right-hand shooters carrying a Glock 19 or Glock 23 will find the 6378 compatible with standard duty belts 1.5 inches and wider. The paddle system distributes holster weight across a larger area of the belt, reducing pressure points during prolonged wear. This configuration has been fielded by patrol divisions, federal task forces, and private security teams since its introduction, making it a category standard for operators requiring ALS-level security at service-pistol speeds.
