Frequently Asked Questions
Which handguns are compatible with the Safariland 578 GLS Pro-Fit?
The 578 Pro-Fit is designed to fit over 60 popular semi-automatic handguns, including models from Glock, Smith & Wesson, Sig Sauer, Springfield Armory, and more. The adjustable retention mechanism can be customized to securely fit your specific firearm. We recommend verifying your handgun model against Safariland's official compatibility chart before purchasing to ensure a proper fit.
How does the GLS (Grip Lock System) retention work?
The Grip Lock System is a passive retention device built into the holster body. When you holster your firearm, a locking component automatically engages to secure the weapon without any manual action required. To draw, simply apply your middle finger to the release lever as you establish a natural shooting grip — the motion is instinctive and requires no extra steps, making it faster and safer than traditional thumb-break designs.
Can I use this holster for concealed carry or is it duty-use only?
While the Safariland 578 GLS Pro-Fit is built to duty-carry standards, its slim OWB profile and paddle or belt-loop mounting options also make it suitable for concealed carry under a cover garment such as a jacket or loose shirt. It is not specifically designed for IWB (inside-the-waistband) carry. For optimal concealment, pair it with appropriate attire and confirm that carrying this holster configuration is lawful in your jurisdiction.
