The Safariland 578 GLS Pro-Fit (brand part number 578-683-412) is a left-hand, outside-the-waistband holster that brings the Grip Lock System together with SafariSeven construction in a black finish, molded for pistols with a 5.3-inch to 6-inch barrel. GLS retention is an innovative design that automatically secures the weapon when holstered and releases it with a simple thumb press on the draw, so there is no separate lever to fumble under stress. It mounts to the belt with a belt loop/paddle, and the SafariSeven material resists abrasion to the pistol’s finish while standing up to heat and cold better than standard nylon.
