The Model 578 GLS Pro-Fit brings the GLS (Grip Lock System) and SafariSeven together in a customizable holster. The GLS is an innovative technology that automatically secures the weapon when holstered and releases it upon application of the middle finger with a standard shooting grip for a more intuitive and safer release. The holster body is constructed of SafariSeven, a lightweight nylon blend which is completely non-abrasive to a gun's finish, tolerant of extreme high and low temperatures and easy to maintain. It includes an injection-molded paddle and an injection-molded belt loop that is adjustable for maximum comfort and allows the holster to be worn cross draw.
