Key Details
-
Manufacturer: Safariland. You can see the “Safariland” text molded into the top of the paddle and the holster body.
-
Model: 578 GLS Pro-Fit. The “GLS” stands for their proprietary retention technology.
-
Material: SafariSeven, a proprietary nylon blend that is non-abrasive to the firearm’s finish and extremely resistant to heat and cold.
Features
-
Grip Locking System (GLS): This is the “active retention” feature. Unlike the Blackhawk Serpa which uses a finger button, the GLS is released by your middle finger as you take a natural shooting grip on the gun. It is widely considered faster and safer than many other button-release designs.
-
Mounting: It features the standard Safariland Paddle, which is highly secure and features an underside hook to prevent the holster from being pulled off the belt.
-
Universal Fit: Because this is a “Pro-Fit” model, there is a small adjustment screw at the bottom of the holster. By tightening or loosening it, the internal block moves to securely hold various gun widths.
Specifications & Market Value
-
Fit: There are four main sizes (Sub-compact, Compact, Standard, Long). Based on the 7-inch height shown in your photo, this is likely the Standard or Wide-Standard size, which fits common duty pistols like the Glock 17/19, S&W M&P, and Sig P320.
-
Condition: It looks like it’s in great shape. Safariland gear is built like a tank, so surface wear rarely affects performance.

New: These typically retail for $55 – $70.
