Blackhawk T-Series L3D Duty Holster for Glock 17/19, Left Hand

The Blackhawk T-Series (brand part no. 44N500BKL) is a duty-grade holster built around thumb-activated retention that keys off the Master Grip Principle: the moment a hand forms a proper firing grip, the release deactivates naturally, letting the pistol come free under stress without a separate, deliberate motion. Blackhawk T-Series L3D Duty Holster for Glock 17/19, Left Hand is molded specifically to fit Glock 17 and Glock 19 for left-hand carry. The shell is reinforced, injection-molded polymer, and the interior lining is smooth, sound-dampening, and hydrophobic so the holster performs consistently regardless of weather. This is gear built for law enforcement and serious duty or range use, not a lightweight concealment rig, and it holds up to daily wear on a belt.

Key Specifications
