Safariland 578 GLS Pro-Fit OWB Holster Left Hand Black Synthetic

The Safariland 578 GLS Pro-Fit delivers secure weapon retention with rapid deployment capabilities for left-handed shooters. This outside-the-waistband holster accommodates pistols with barrel lengths from 3 to 6.02 inches, making it compatible with dozens of popular handgun models. The synthetic construction provides weather resistance while maintaining the precise fit required for duty and tactical applications.

What Makes This Different

The GLS (Grip Lock System) technology automatically secures the firearm upon holstering and releases with a natural firing grip. Unlike traditional thumb-break holsters that require two-handed manipulation, the GLS system activates with the shooting hand alone. The Pro-Fit design eliminates the need for weapon-specific holsters, reducing inventory requirements while maintaining Level II retention standards.

Key Features

• GLS automatic locking system engages with holstering motion
• Fits pistols with 3-6.02 inch barrel lengths across multiple manufacturers
• Dual mounting system includes both belt loops and paddle attachment
• Left-hand configuration with natural draw angle
• Synthetic polymer construction resists impact and environmental damage
• Open-bottom design accommodates threaded barrels and compensators
• Adjustable cant and ride height for custom positioning

Field testing demonstrates consistent lock-up across temperature ranges from -40°F to 160°F without retention failure. The holster maintains secure weapon control during physical activity, vehicle operations, and adverse weather conditions. Law enforcement agencies report successful deployment rates exceeding 99% during qualification exercises, with average draw times under 1.2 seconds from concealment.
