Fast, sure target identification with the additional tactical advantage of a powerful Red Class 3R Laser.

Even under low light conditions and during more complex operations, fast, sure target identification and acquisition is a necessity for survival in Special Operations. With the GTL 21 Tactical Light, GLOCK offers the solution for those users who cannot afford compromise. You’ll find the same, proven GLOCK Xenon illumination technology, integrated, ergonomic design, and easy operation as the light-only GTL 10. But the GTL 21 offers the additional tactical advantage of a powerful red class 3R Laser inserted into the shockproof and waterproof polymer housing. Simple and accurate adjustability in both axes guarantees precise targeting. Software-controlled temperature monitoring of the laser diodes permits operation in various temperature ranges.


  • A Powerful Red Class 3R Laser
  • High-Tech Polymer Casing
  • Adjustable Focusing
  • Xenon-Technology Electronics
  • Ergonomically-Placed "Soft Switch"
  • Simple and Ambidextrous Operation
  • Mounts Rigidly to Pistol’s Rail in Seconds

The GLOCK Tactical Light 21 extends the revolutionary concept of the GLOCK Safe Action Pistol as smoothly as its tapered high-tech polymer case integrates with the pistol itself. The advanced Xenon lighting technology delivers 60 lumens of maximum illumination continuity and optimal efficiency over the life of its 2 CR123 Lithium batteries, thanks to the “smart” electronic components which control it. All of this is available at the touch of the ergonomically-placed "Soft Switch". Embedding it all in the proven GLOCK polymer makes it virtually shockproof.

The smoothly integrated light-Laser module mounts rigidly onto the pistol’s accessory rail in seconds. Operation is simple and ambidextrous, even with tactical gloves. It all works together with your GLOCK pistol to provide a flexible solution for practically any target illumination situation—creating a superior tactical weapon/light system no police or military special unit should be without.
