The BlackHawk T-Series L3D for Glock 17 with TLR-7 is a left-hand, Level 3 retention holster built for shooters who need active security without sacrificing draw speed. Whether you carry for duty, competition, or personal protection, this holster combines thumb-activated retention with the natural drawing motion of the Master Grip Principle—so your draw stays intuitive even under stress. The reinforced polymer construction and low-friction internal lining mean smooth, silent presentations in any weather or environment.

BlackHawk engineered the T-Series L3D with dual security layers: the thumb-activated retention lever and a passive retention strap across the back of the slide. That two-tier approach keeps your Glock locked down while you move, train, or work—and both release naturally as part of your draw stroke. The sound-dampening lining helps keep your gun quiet during holstering and unholstering, a feature that matters on the range, in duty shifts, or anywhere discretion counts.

This demo/used unit comes with the Jacket Slot Belt Loop already attached, so you're ready to configure your carry setup right out of the box. The slim profile and durable materials handle whatever conditions you throw at it—rain, dust, heat, cold—without the bulk of less-refined designs.
