Safariland 578 GLS Pro-Fit OWB Holster FDE Right Hand 3.3-4.25"

The Safariland 578283551 GLS Pro-Fit holster delivers secure retention and rapid deployment for mid-size pistols in a versatile outside-the-waistband configuration. This polymer holster accommodates barrels from 3.30" to 4.25" while maintaining the proven GLS (Grip Lock System) that has become standard for law enforcement agencies nationwide.

What Makes This Different

The GLS Pro-Fit system eliminates the guesswork of holster selection by fitting multiple pistol models within its specified barrel length range. Unlike traditional molded holsters that require exact model matching, this design uses an adjustable trigger guard lock that secures dozens of popular pistol models. The Flat Dark Earth polymer construction resists impact damage and environmental wear while weighing significantly less than leather alternatives.

Key Features

• GLS Grip Lock System activates automatically during holstering, releases with natural firing grip
• Fits pistols with 3.30" to 4.25" barrel lengths including Glock 19/23, S&W M&P Compact, Sig P320 Carry
• Dual mounting system includes both paddle attachment and belt loops for 1.50" to 2.25" belts
• Flat Dark Earth polymer construction provides corrosion resistance and reduced weight
• Right-hand draw configuration with adjustable cant for optimal positioning
• Open muzzle design accommodates threaded barrels and compensators
• Low-profile design reduces printing under concealment garments

Field testing demonstrates consistent lock engagement across compatible pistol models, with the GLS mechanism requiring deliberate grip pressure to disengage. The system functions reliably in temperatures from -40°F to 160°F and maintains retention through mud, sand, and water exposure. Competition shooters report draw times under one second once muscle memory develops, while duty officers appreciate the passive retention that doesn't require conscious activation.
