- Secondary strap across the back of the firearm adds an extra retention layer
- Fits Streamlight TLR-1 and TLR-2 weapon lights mounted on Glock 21

Who This Is For
The T-Series L3D is purpose-built for duty carry — ideal for law enforcement officers, armed security personnel, and military professionals who carry the full-size Glock 21 with a Streamlight TLR-1 or TLR-2 light and need a holster that won't compromise retention under physical stress, adverse weather, or high-stakes scenarios. Right-hand draw configuration in an all-black finish suits both uniform and plainclothes duty roles.

Frequently Asked Questions
Will this holster fit a Glock 21 without a weapon light attached?
The T-Series L3D is specifically designed to accommodate the Glock 21 with a Streamlight TLR-1 or TLR-2 weapon light. Because the light rail is factored into the holster's retention geometry, it is not recommended for use with a bare, light-less Glock 21, as the fit and retention may not be secure without the light present.
Does the thumb-activated retention slow down the draw stroke?
No — the T-Series L3D is engineered around the Master Grip Principle, meaning the retention release is naturally activated as your hand achieves a proper firing grip. With practice, the release motion becomes intuitive and adds minimal time to your draw, making it one of the fastest Level 3 duty holsters available.
What belt widths are compatible with the included Jacket Slot Belt Loop?
The Jacket Slot Belt Loop included with the T-Series L3D is designed to fit standard duty belts up to approximately 2.25 inches wide, which covers most law enforcement and tactical belt platforms. For wider or specialized belt systems, Blackhawk offers optional mounting accessories sold separately.
