Safariland 578 GLS Pro-Fit Long Slide Left Hand Holster

Safariland Model 578 GLS Pro-Fit Holster

The Model 578 represents a thoughtful approach to outside-the-waistband carry, combining two proven technologies into a single, versatile platform.

Grip Lock System

The GLS (Grip Lock System) is the standout feature here. It automatically secures your weapon when holstered, then releases cleanly when you apply your middle finger with a standard shooting grip. This design is intuitive—your natural draw motion activates the release without requiring you to think about a secondary manipulation. For those concerned with retention and safety, this is a meaningful advancement.

Construction and Materials

The holster body is built from SafariSeven, a lightweight nylon blend engineered to be completely non-abrasive to your firearm's finish. It handles temperature extremes without degradation and requires minimal maintenance—simply wipe clean as needed.

Versatility and Fit

The Pro-Fit design adjusts to accommodate a wide variety of firearms, making it a practical choice if your collection grows. For this configuration, it's sized for long-slide handguns similar to the Glock 34, 35, and 17L.

Carry Options

The holster includes both an injection-molded paddle and an adjustable belt loop, allowing you to choose your carry method. The adjustable belt loop also permits cross-draw positioning for those who prefer it.
