Who This Is For
The Blackhawk T-Series L2D is purpose-built for law enforcement officers, security professionals, and serious concealed carriers who run a Glock 21 with a Streamlight TLR-1 or TLR-2 light. If you need a holster that balances rock-solid retention with a fast, natural draw stroke — especially under high-stress conditions — this is an ideal choice for both on-duty use and range training.

Frequently Asked Questions
Will this holster fit a Glock 21 without a weapon light attached?
The Blackhawk T-Series L2D is specifically molded to accommodate a Glock 21 with a Streamlight TLR-1 or TLR-2 light. Because the retention and fit are shaped around the light rail and light body, it is not recommended for use with a bare, light-less Glock 21. For a Glock 21 without a light, a different T-Series SKU designed for that configuration would be the appropriate choice.
What does "Master Grip Principle" mean and how does it affect the draw?
The Master Grip Principle means your thumb naturally disengages the retention device as you establish a full firing grip on the pistol — there is no separate, conscious step required to release the holster. This reduces the chance of fumbling the draw under stress and allows for a faster, more consistent presentation from the holster, which is especially valuable in high-pressure situations.
Can this holster be used with other belt attachment systems beyond the included loop?
The T-Series L2D ships with a jacket slot belt loop, but Blackhawk's T-Series platform is designed to be compatible with a range of optional attachment systems, including paddle mounts and duty-belt attachments sold separately. This modular design makes it easy to adapt the holster to different carry methods without replacing the entire holster body.
