A compact, high-output light designed to pair seamlessly with your Glock 27.

Compact Design: Wow, talk about small but mighty! The TLR-7A Flex sits at a mere 2.5 inches and weighs next to nothing—only 2.4 ounces. 

That means it fits my Glock 27 snugly without making it feel like I’m hauling around a brick. The compactness is a major plus if you want to carry concealed or maintain the Glock’s natural balance.

High Output: Don’t let its size fool you; this light cranks out up to 500 lumens. That’s bright enough to disorient an intruder or light up an unlit parking lot. 

Thanks to the Borofloat glass, the beam stays sharp and focused. You get a lot of light exactly where you need it, with a tight center hotspot that’s ideal for precise aiming.

Quick Mounting: Gotta love how easy it is to mount this bad boy! The TLR-7A Flex has a “quick mount” system, letting you attach or detach it in a flash—no tools are needed.

If you’re in a situation where every second counts, you’ll be glad you have this feature. It’s a real time-saver.

Durable Construction: Here’s where the rubber meets the road. The TLR-7A is built from anodized machined aluminum. 

This means it can take a beating and keep on shining. I’ve had mine out in various conditions, and it hasn’t flinched. It’s also IPX7 rated, so a little rain or accidental drop in a puddle won’t spell disaster.

Safe Off Feature: A nifty addition that’s easy to overlook is the safe-off feature. It prevents accidental activation, so you won’t find yourself suddenly broadcasting your position or, worse, draining your battery when you least expect it.

Why I Love It: What’s not to love? It’s compact, bright, and easy to use, with features that make it both practical and reliable.

My Experience

I’ve put this light through its paces in real-world scenarios. 

It’s performed flawlessly, from late-night range sessions to simulated home defense drills. Its size complements my Glock 27 without sacrificing power or functionality.

A budget-friendly tactical light with a green laser, designed for versatile applications, including use with your Glock 27.

High Power Output: Let’s kick things off with the jaw-dropping 1350 lumens this light produces. 

I was initially skeptical, given the light’s affordable price point, but this thing is bright! Whether you need to disorient an attacker or illuminate a large area, this light covers you.

Weather Resistant: Durability matters and the OLIGHT Baldr Pro delivers. Made from an aluminum alloy, it’s got an IPX7 water resistance rating. I’ve used it in the rain, and let’s just say it passed the test with flying colors. 

It’s reliable through and through, so don’t fret about those wet or snowy conditions.

Reliable Activation Switch: If you can’t turn your light on when you need it, what’s the point, right? The tail switch on the Baldr Pro is dependable and tactile. 

You can feel it easily in the dark, and it’s ambidextrous for added convenience. It’s one of those small but essential features that make a big difference in high-stress situations.

Green Light: Yep, this light offers a green laser along with its white LED. The green light is really bright and helps a lot in different lighting conditions. 

It adds another layer of functionality, especially if you’re into tactical shooting or need that extra aim assistance.

Easy Operation: Installing the light is a snap, with adjustable screws that work with both 1913 and GL rails. While you do need a tool to get it on there, once it’s set up, the ease of use is terrific. The interface is intuitive, so you won’t fumble around trying to figure it out.

Why I Love It: For the price point, the feature set is outstanding. High output, water resistance, reliable activation, and the added bonus of a green laser—what more could you ask for?

My Experience

I’ve tested this light under a variety of conditions, from indoor range shooting to outdoor nighttime use. It performed consistently well. 

The high output and reliable switch came in handy, especially when working on rapid target acquisition drills.


  • Budget-friendly without skimping on features
  • High 1350-lumen output
  • Durable and weather-resistant
  • Reliable activation switch
  • Comes with a green light for added versatility

  • Does NOT have a Laser

A lightweight, dual-function tactical light with a red laser, designed for Glock 27 users who need versatility and power.

Featherweight Champ: This light barely tips the scales, folks. Weighing in at just 1.1 ounces with the battery, you’ll hardly notice it’s there. But don’t let the featherweight status fool you. 

It’s a small package with a big performance, and it won’t throw off the balance of your Glock 27. That’s super crucial when you’re in a situation where stability is everything.

Dual Functionality: Light and Laser: Let’s talk about the star features: the 100-lumen C4 LED light and the red aiming laser. This isn’t just a flashlight. It’s an integrated system that allows you to be more accurate and adaptable. 

The LED light is robust and can go the distance—literally, with a life expectancy of over 30,000 hours. Plus, the red laser is a game-changer for nighttime shooting.

No Tools, No Problems: The integrated rail clamp makes no fuss in attaching or detaching this unit from your Glock. There’s no need for a toolbox, no extra sweat; it’s just click, snap, and you’re good to go. 

Ambidextrous Ease: Now, lefties, listen up! The TLR-6 has you covered with an ambidextrous on/off switch. Right-handed or left-handed, you’re only a thumb flick away from illumination or laser targeting. It makes life just that much easier when you’re under pressure.

Longevity and Reliability: The Streamlight TLR-6 is a trustworthy companion. The LED light is rated for a ridiculous number of hours, and the construction seems robust enough to handle the usual knocks and bumps. And let’s not forget reliability also means always being ready when you need it most.

Why I Love It: For me, it’s all about dual functionality and ease of use. Sometimes, you need a light; sometimes, you need a laser. 

Why not have both without added bulk? It’s streamlined, smart, and super effective.

My Experience

I’ve had this out in a few different settings—daytime, nighttime, rain, and even some foggy conditions. It’s delivered every time. 

The red laser feature was particularly handy when I practiced some low-light shooting. Aiming felt more intuitive, and I could quickly toggle between the light and laser features.


  • Remarkably lightweight without sacrificing quality
  • Dual functionality with a powerful LED light and red laser
  • Simple and quick tool-free installation
  • Ambidextrous controls for universal use
  • Durable and long-lasting, thanks to solid construction and LED lifespan


  • Lower lumens compared to some other models, but still adequate for most situations

A tactical light with a special off-white 600-lumen LED and universal compatibility, designed for shooters who crave adaptability and peak performance.

Illumination: The light emitted is biased in the yellowish-green spectrum, which is optimal for our eyes. 

This color spectrum enables better vision and greater detail in high-stress situations. Trust me, you’ll see the difference immediately when you switch it on.

Precision in a Beam: The light features a precision TIR lens. It produces a tight, focused beam with just enough spill to illuminate your peripheral vision. 

And that’s vital because awareness of your surroundings can be a life-saver. The TIR lens makes sure you see clearly without unnecessary glare or shadowy areas.

One-Finger Switching: The ergonomic one-finger switch allows for momentary or constant light. It’s ambidextrous, which is great for southpaws like me. 

That means I can comfortably operate the light regardless of which hand I’m using to hold my Glock 27. The action is smooth and highly intuitive.

Customizable Control: An optional pressure-activated switch gives you even finer control. Once you get the hang of it, you’ll realize how much easier and quicker it makes your targeting and activation. 

Why I Love It: The illumination won me over. Not only does it pack enough lumens to light up a room, but it does so in a way that actually helps my eyes adjust quicker to changing light conditions. It’s a thoughtful design at its best.

My Experience

I put this bad boy to the test in both outdoor and indoor ranges and even during a late-night training session. Every time, it was a reliable performer. 

The one-finger switch made operations smooth, and the option for a pressure-activated switch is perfect for those who like extra customization.


  • Exceptional light quality tailored for human vision
  • Versatile and precise TIR lens
  • Ergonomic and ambidextrous one-finger switch
  • Universal and Picatinny rail compatibility
  • Customizable control with optional pressure-activated switch


  • Compatibility issues with some aftermarket holsters, so you might need to shop around for the perfect fit

While other lights offered unique advantages and had their own strengths, the TLR-7A Flex consistently met all my key criteria.
