Description
The Blackhawk T-Series L2C is a retention holster built around one key principle: your draw should work the way your hand naturally wants to move. When you grip the gun, your thumb falls right on the release lever without any awkward finger gymnastics. This is what Blackhawk calls the Master Grip Principle, and it makes the difference between a holster that slows you down and one that feels instinctive from your first draw.
T-Series Design and Construction
Blackhawk engineered this holster using a dual-shot injection molding process that combines a reinforced outer polymer shell with a low-friction internal layer. The result is durability without unnecessary bulk. The hydrophobic lining keeps things working smoothly in wet conditions while the sound-dampening material ensures quiet, stealthy drawing and holstering. The holster's non-light bearing design is purpose-built for stock pistols, delivering trigger guard protection from every angle without compromising draw speed.
Level 2 Retention and Optics Ready
The L2C meets certified Level 2 retention standards through both active and passive mechanisms. The thumb lever releases a spring-loaded trigger guard lock, while passive retention can be adjusted via a Phillips screw for your preferred feel. An open-top design with a speed cut lets you bring the barrel up faster and funnel the gun back in quickly during reholstering. The optics cut on the front runs with any standard slide-mounted red dot, and the wide muzzle opening prevents debris from becoming trapped inside.
What Comes in the Box
You get the holster with a quick dual release belt loop already mounted, plus a 2-slot belt loop for traditional belt carry. Both attachment styles work with Blackhawk's modular belt loop system, so you've got carry options that match how you want to set things up.

Frequently Asked Questions
Does the T-Series L2C work with red-dot sights?
Yes. The holster features a large optics cut on the front and is compatible with any slide-mounted red-dot sight. The low-profile design means your reflex sight won't interfere with draw or reholstering, and the open muzzle design prevents debris from getting trapped inside.
What makes the thumb release different from older Blackhawk models?
The T-Series moves the release lever from your trigger finger to your thumb, which is more intuitive and faster. When you get a proper grip on the gun, your thumb naturally falls on the release without any extra hand contortions. This aligns with what most professional and competitive users prefer.
Can I adjust the retention on the L2C?
Yes, the passive retention is adjustable. There's a Phillips head screw near the front of the trigger guard that lets you dial the fit tighter or looser to your preference. The default setting works well for most users straight out of the box.
Will this holster fit other Glock models not listed?
The L2C is specifically molded for Glock 17/22/31/34/35/41/47 models. Due to the tight, precision fit, it's not designed for other generations or sizes. The open muzzle does allow compatible Glock models like the 19 to fit in some cases, but the primary fit is for the models listed.
