TLR-6 100-Lumen Tactical Light for Glock 42/43/43X/48 - Compact Weapon

Our review of the TLR-6 100-Lumen Tactical Light focuses on compact handgun users who want a no-frills, firmly mounted illumination option for Glock 42/43/43X/48 pistols. The bottom line: this light is for shooters who prioritize a very small, lightweight unit that clamps to the trigger guard and delivers usable white light for target identification without adding bulk. It is not a multipurpose rail system lamp, but for owners of the specified Glock models it solves the common problem of finding a discreet, secure light that stays in place and allows battery changes without removing the unit.

Key Features

• Model-specific mounting: Designed to securely attach to the trigger guard on Glock 42/43/43X/48, providing a tight, model-specific fit that limits wobble during carry.
• Ultra lightweight and compact: The small footprint keeps overall handgun profile low so it remains comfortable for concealed carry and handling.
• Tool-less battery replacement: Batteries can be replaced while the light remains mounted on the weapon, making maintenance quick without field-stripping the unit.
• Durable zero retention: Windage and elevation adjustment screws are mounted in bushings to preserve a dependable zero over time.
• Impact tested: One meter impact resistance testing shows the unit is built to withstand everyday drops and recoil stresses expected on compact pistols.

Who It's For

This compact tactical light best serves owners of Glock 42, 43, 43X and 48 who want an ultra compact, purpose-built option that clamps to the trigger guard rather than using a rail. It is ideal for concealed carriers and those who prioritize a low profile and easy, tool-less battery access.

It is not the right choice for users who need a universal rail-mounted weapon light, higher lumen output for long-range illumination, or models that attach to MOS-equipped slides. Those seeking a multi-platform solution should look to rail-compatible lights instead.

Pros & Cons

Pros

• Bright enough for quick target identification on short-range encounters while remaining compact and lightweight.
• Secure mounting that customers report stays in place during carry and handling, reducing the need for frequent retightening.
• Easy installation and removal with tool-less battery replacement saves time and keeps the light on the gun for maintenance.

Cons

• Limited to select Glock models with no rail or MOS, so it will not fit pistols that require a different attachment method.
• Some users report intermittent functionality issues, so buyers should verify operation on arrival.
