Streamlight TLR-6 100-Lumen Tactical Light for Glock 42/43 - Compact

Our review of the Streamlight TLR-6 finds it aimed squarely at owners of GLOCK 42, 43, 43X and 48 who want a compact, integrated light and red aiming beam without adding bulk. The single biggest reason to buy is the combination of a usable 100-lumen white LED and a factory-integrated red laser in a tool-less, trigger-guard mounting package that does not require removal for battery changes. For everyday carry subcompacts where size, quick attachment, and simple operation matter, this is a practical, no-frills choice.

Key Features

• Compact white LED: The 100-lumen LED delivers a bright, focused beam suitable for target identification at close to medium range.
• Integrated red laser: The red aiming beam provides a clear point of aim with a wavelength in the 640-660nm range and output under 5mW.
• Tool-less battery access: Batteries can be replaced without removing the device from the weapon or re-sighting the beam, saving time in the field.
• Secure trigger-guard mount: Designed to attach to the trigger guard on GLOCK subcompacts for a low-profile, factory-like fit.
• Ambidextrous controls: Momentary and steady on/off switch arrangement works for both left- and right-handed shooters for fast activation.
• Durable polymer housing: Impact-resistant polymer construction has been tested to 1-meter impacts for day-to-day carry durability.

Who It's For

The TLR-6 is best for concealed-carry owners of GLOCK 42/43/43X/48 who prioritize a minimal footprint and straightforward operation. It fits the trigger-guard of these models and gives a practical light and laser combo for identification and close-range aiming without adding significant bulk or weight.

Those who need very long run times, exceptionally bright flood illumination, or a universal mounting solution for many pistol models should look elsewhere; this unit is purpose-built for a narrow set of GLOCK subcompacts and performs best in that specific role.

Pros & Cons

Pros

• Small, low-profile package that preserves concealability on subcompact GLOCK pistols.
• Reliable 100-lumen white light with a usable beam for target ID and short-range use.
• Integrated red laser with class 3R output for fast pointing without additional attachments.
• Tool-less battery replacement and ambidextrous controls improve ease of use.

Cons

• Fit is specific to certain GLOCK models; not a universal mount for other pistols.
• Some users report occasional retention issues under heavy use, so verify secure attachment before reliance in training or carry.
