The Safariland 578 GLS Pro-Fit Holster is a shooter's dream and a force to be reckoned with. Safariland designed the 578 Pro-Fit with an ambidextrous adjustable belt loop feature for our south paw friends. The trademarked GLS (Grip Lock System), coupled with the durability and strength of the brand's signature SafariSeven™ construction, allows for the 578 holster to safely accommodate over 175 gun fits. What's more, the GLS locking technology fastens the firearm automatically when it's cradled, and release is made easy with a press of the middle finger while using your natural shooting grip. No fancy finger work necessary! Safariland's 578 Pro-Fit and its SafariSeven™ composition is non-abrasive and designed to not scratch your gun metal, and its tolerance of extreme temperatures in both directions keep it crack and warp free. Finally, the 578 GLS Pro-Fit comes with an injection molded paddle, increasing the holster's versatility that much more.
