Glock introduced the GTL II weapon-mounted light at SHOT Show 2025 as the successor to its earlier GTL series. The light outputs 600 lumens and 11,100 candela and is built for most double-stack Glock pistols along with certain clones, but it does not fit Slimline models.

Installation uses a dedicated latch that slides onto the Picatinny rail groove and locks by passing through the housing. Paddle switches rest along the trigger-guard sides and carry surface texture, while the kit supplies two push and two touch controls plus a tool for exchanging them.
