Glock Tactical Light present a solution for practically all conceivable target illumination situations. Able to function independently or in concert with the high intensity Xenon white light, the red laser/ 70 lumen light module is easily yet securely mounted to Glock pistols with a rail mount system. The laser is able to be zeroed with pinpoint accuracy and is designed specifically for "duty use" conditions. Both white light and laser respond to the ergonomically designed "Soft Switch". It is ideal for military, law enforcement and self-defense situations. The GTL 22 includes dimmer switch.
