Safariland #578 7Ts Pro-Fit GLS Holster Size 0 Long Slide Similar To Glock 34/35/17L Black Left Hand

The Safariland #578 7Ts Pro-Fit GLS Holster Size 0 for Long Slide Glock 34/35/17L in black, left-hand configuration, is a level-I retention holster engineered for operators who demand intuitive weapon security without complicated manipulation. Built on Safariland's proven GLS (Grip Lock System) platform, this holster automatically secures the firearm when holstered and releases cleanly upon application of the middle finger using a standard shooting grip—a design feature that minimizes training curve and maximizes safety during high-stress deployment.

The Pro-Fit design accommodates over 175 firearms through adjustable compatibility, though this Size 0 variant is optimized for long-slide platforms including Glock 34, 35, and 17L pistols. The holster body is constructed to deliver consistent performance across extended duty cycles while the left-hand configuration serves the estimated 10% of law enforcement and civilian operators who draw from the support side. Its compact footprint and durable material composition support both uniform carry and tactical operations without unnecessary bulk or weight penalty.

This model is suited for patrol officers, tactical team members, and serious recreational shooters who prioritize a manual retention system with transparent release mechanics. The GLS platform eliminates ambiguity—there is no secondary button to locate, no hood to clear—making it reliable for shooters wearing gloves, operating in low light, or transitioning between equipment configurations. The #578 7Ts Pro-Fit represents a pragmatic choice for those who value a straightforward retention philosophy backed by law enforcement field testing.
