The Safariland 578 GLS Pro-Fit Holster (brand part no. 578-450-551) is a right-hand outside-the-waistband holster finished in FDE and engineered to adjust to a wide range of duty and carry pistols. Safariland’s Pro-Fit shell is customizable and adjusts to securely fit over 60 different firearms, making the 578 a practical choice for ranges, agencies, or shooters who carry more than one handgun. The standout feature is the GLS, or Grip Lock System, which automatically secures the weapon on holstering and releases with a simple middle-finger press during a standard shooting grip. That combination of universal fit and automatic retention makes the 578 GLS a strong option for training, duty backup, or a primary concealment rig.
