What To Look For in Your New Glock Light

So what makes for the best tactical flashlight with a laser for Glock? Before you make that light/laser upgrade for your Glock, let’s have a look at them.

Light Output

You can know how bright a light is by looking at how many lumens it outputs. The more lumens, the brighter the light is.

Look for a minimum 100-lumens of brightness, but keep in mind that some models reach up to 800 lumens, which is a distinct difference.

It’s also worth considering that high-brightness modes drain your batteries faster than they would in low ones. Make sure to balance this out as best you can.

Strobe Mode

Strobe lights are known for their effects on the eyes and vision. The flickering between bright pulses causes disorientation and diminishes peripheral vision. These extremely important few seconds gained should be enough for you to gain the upper hand in situations where your life is threatened.

Laser Sight

Since the advent of lasers, it didn’t take long for manufacturers to adapt them to weapons. They greatly improve aim by providing long-range targeting and can also be used as a deterrent. 

Red lasers are the most common, but their beams aren’t as visible as green ones. This is due to their different properties when interacting with molecules or particles in the atmosphere. 

Green lasers can be scattered by the air alone without the need for particles, as is the case with the red laser.

Glock Model and Generation

Not all tactical flashlights are designed to mount on all models and generations of Glocks, so make sure the light you get fits on your generation of Glock. There are currently five generations of Glocks, with the fifth being the most recent.

The ability to mount tactical lights and laser sights began with third-generation Glocks onward. However, each generation has several models.


It’s crucial for tactical lights to be built for reliability. There’s no point in having something that can easily break down in the middle of a shootout, rendering you blind and unable to take your shot.

As such, the best flashlights with lasers for Glocks should have good resistance against impact, water, and weapon recoil. Construction mostly involves using aircraft-grade aluminum along with a hard plastic polymer.

Size and Weight

While not the most important factor to consider, it’s still something to consider to aid with usability. Avoid tactical flashlights that cause the gun to be bulky and obtrusive.

They’re also not supposed to be heavy enough to shift the weapon’s center of mass, making it more unbalanced when held.

The best flashlight with a laser for Glock would typically be between 2 and 6.25 inches long, and it should weigh no more than 5 ounces.

Windage and Elevation

Being able to adjust your laser sighting for windage and elevation is a necessity. This way, when you take your shot, it doesn’t end up going off target.

Confused between the two? Windage deals with horizontal adjustments, whereas elevation deals with vertical adjustment.

Depending on the flashlight, you can make these adjustments either using tools or directly with your hand. The latter is more common with smaller tactical flashlights that don’t have room for a rotatable knob.

Ease of Use

In tactical situations, timing is everything. As such, the ability to quickly switch on the light and laser is paramount. These switches should be easily accessible using either of your hands. Additionally, they also shouldn’t obstruct your overall use of the gun.

This is why flashlights with switches that suit ambidextrous use are ideal for switching between different light modes as well as turning it on and off.

Some products have even more unique technology, where the light activates the moment you draw your gun, without the need to use any switches.

Best Overall Flashlight with a Laser for Glocks

Streamlight 69240 TLR-4 Compact Rail Mounted Tactical Light

The Streamlight 69240 TLR-4 is a great addition to your Glock and takes the trophy for the best flashlight with laser for Glock.

The light shines at 125 lumens and uses a combination of focused and wide beams for optimal peripheral and close-up illumination. In addition to the light, there’s a red laser that you can operate on its own or with the light using an ambidextrous toggle switch. This combines well with the adjustment screw for windage and elevation to provide zero retention of the laser.

Powered by one CR2 lithium battery, you can keep the light and laser running for a maximum of 1.5 hours before running out of juice. Additionally, the product measures 2.73 inches long and weighs 2.81 ounces.

The rail clamp system is a one-hand mount and secure system while being compatible with a broad range of guns in addition to the Glock—Beretta, Kimber, Ruger, Sig Sauer, and Smith & Wesson.

It emits 800 lumens, delivering high brightness in a wide beam pattern up to 309 yards. In addition, the laser is green for long-range targeting.

We like the inclusion of a strobe mode, which can be used separately or together with the laser. The runtime for both is 1.5 hours but is 17 hours on just the laser using two CR123A batteries, which are included.

Mounting it is straightforward and easy using the clamp system, keeping your hands away from the muzzle. Moreover, it can be mounted on a broad range of handguns as well as Picatinny rails.

Operating the three modes—laser, light, and laser, and light only—is via a simple button on both sides.

Two CR1/3N lithium batteries provide enough juice to keep the light-powered up for 1 hour, with or without a laser, or the laser alone powered up to 11 hours. The batteries are easily replaced without tools or detaching the flashlight and reattaching it, or re-zeroing the laser afterward. 

This flashlight is also made from a durable polymer that’s impact-resistant up to 1 meter. Additionally, it’s water-resistant with an IPX4 rating and can operate between -20 and 120 degrees Fahrenheit.

With both the light and laser on, it’ll run for 2 hours via one CR2 battery, although we’re unable to confirm runtime in single-use.

Finally, it’s designed to seamlessly integrate with a Glock 42 or 43’s frames and then activates when the gun’s held in a firing grip.
