1. Viridian C5L Universal Green Laser Light

Viridian C5L Universal Green Laser for Glock 19

Number one on our list of best Glock 19 light is Viridian C5L Universal Green Laser. Viridian is a famous brand that is steadily gaining popularity in the market and garnering tons of positive feedback. Viridian C5L Universal Green Laser has quickly received consumers’ attention with many advanced technologies applied.

First, the green laser light is one of the product’s most distinguishing features. It has a range of illumination settings, including green laser sight and white light, to provide you more freedom in seeing what you need. The green tactical laser can swiftly target and highlight threats effectively.

Because it is closer to the center of the color spectrum, greenlight is easier to see than red light and is visible in the daytime. Furthermore, the Viridian green laser is one of the brightest lasers on the market, producing 100 lumens of bright light and up to 140 lumens in strobe mode.

White light isn’t very remarkable, but it can blind someone to reduce their ability to combat you at that time. It’s also straightforward to switch between the various illumination modes. All elements are simple to use; just press both buttons and cycle through until you reach the desired setting.

It also has ECR Instant-On (Enhanced Combat Readiness), which is a huge plus. In a deadly situation where operating skills diminish, activating lights or lasers can be difficult, which may put you at a disadvantage. To overcome this issue, you can pre-program the light or laser to turn it on. Then, when you take out the pistol from the holster, you always have the light on in an emergency, and you’ll be able to easily turn it off.

Viridian products are also known for their toughness and small size, which are ideal for the Glock 19 and most other handguns. Its compactness provides a secure connection between the muzzle and the trigger guard. The C5L’s casing is composed of aircraft-grade aluminum, making it one of the most robust choices available.

When it comes to the product’s drawbacks, the on/off switch is not convenient. Furthermore, I hope that the battery life will be increased to allow for a longer time.


  • Make sighting easy
  • Very bright and crisp green laser
  • Strobe function with 140 lumens
  • Lightweight and long-lasting
  • Compact design


  • Switch on or off is not so convenient

Besides, thanks to ECR Instant-On, lights are available immediately in dangerous scenarios when taking the pistol out of the holster.

2. Crimson Trace LG-639G Lasergrips Flashlight

Crimson Trace LG-639G Lasergrips for Glock 19

If you are looking for the best Glock 19 light and the laser is placed in a relatively unique position, refer to Crimson Trace LG-639G Lasergrips. Crimson Trace, the proven leader in laser aiming and tactical lighting systems for handguns, has introduced this model of grip style laser for Glock 19, 23, 25, 32, and 38.

Its location towards the back of the grip makes it unique and works effectively. Because it’s in the rear, it doesn’t interfere with holstering as much as the weapon-mounted lights do. However, if you are not used to it, the additional pad behind you may seem unpleasant and bulky. Besides, it is easily adjustable for windage and elevation with the supplied tool.

Crimson Trace’s unique ” Instinctive Activation” is one of the reasons they dominate the Laser industry. As a result, when you take the gun, the light will immediately turn on. You won’t have to rummage around in the dark for switches as on other models.

By utilizing the Crimson Trace Laser Grip, you will significantly enhance your shooting. The laser has a sighted range of 50′, which is ideal for self-defense and other tactical tasks. You can get to the target faster and take the next shots more rapidly with laser support, even than with a viewfinder.

A good feature is also the battery life. If you do not use it frequently, it can last a long period because it has a 4-hour running time for continuous usage, much longer than any competitors. Fortunately, the battery is simple to replace, taking less than 5 minutes to change out and reinstall.

When picking, keep in mind that the LG-639 has a red diode and the LG-639G has a green diode. The red option is pretty good, especially at night, but the green light is better for seeing well in both day and night time.

The only drawback I can find is the price. It is expensive in comparison to others, but its quality and performance are outstanding.


  • Unique grip style laser design
  • Convenient to use and hold the gun
  • Made of high-quality materials
  • Holstering is not affected


  • Pricey

They allow you to activate the gadget with either your trigger finger or your thumb. The light/laser combination allows the device to be configured for dual lights, light only, or laser only.

These two tactical lights have some similarities in that they both produce 500 lumens and have a run duration of an hour and a half. You may also use the strobe feature and have both of them locked out. Interchangeable lenses are available.

This great light for Glock 19 is only 0.01 oz lighter and 0.07″ shorter than the TLR7 A in terms of setup. The weight difference is scarcely discernible. TLR-7 has a pointed-shaped nose, while the other merely has a flat one.

Thanks to the brighter beam, it is rated higher than the TLR 7A. Its beam is somewhat brighter than the TLR 7A, and it’s color-neutral, allowing for more accurate color reproduction in low light.

  • Great for concealed carry & faster holstering
  • Brighter beam than TLR 7A (More neutral)
  • Super lightweight
  • Beam pattern for close-range applications


  • It’s not flexible

Things To Look for The Best Tactical Flashlight for Glock 19

Top 8 Best Tactical Lights for Glock 19 Options (Gen 3,4,5 Compact)

Dimensions and configuration

When selecting a tactical light for a pistol, the first and most important consideration is the gun’s size and configuration. Each is built differently to accommodate various gun models. Furthermore, the length of these lights will be no longer than the pistol’s barrel, allowing your hand flexible control. Assemble the rails to fit together and have a strong connection that makes working as simple as feasible.


Your gun barrel will tilt forward, causing the gun to lose balance. Choose Glock 19 lights that are either lightweight or have little impact on the total weight of the weapon when mounted. I think you don’t want anything that adds to the weight of your weapon.

Easy to use

Lights must be disassembled and manipulated quickly, especially in emergencies. You’ll need a laser light assembly that’s simple to install and remove from your weapon.

Some laser light combinations use a mechanical switch panel, while others use an automated switch. Furthermore, some Viridian devices include an ERC Instant-on feature that ensures the light mode is always engaged with the default setting when removed from the holster.


Having a lot of lumens isn’t always the best option. Consider how you’ll be using your handgun light while deciding on the brightness setting. Because powerful light may be confusing and perhaps blind prospective intruders, homeowners generally desire maximum brightness levels.

Range of laser beam

When targeting an object, you need a long-range laser. This way, no matter how far away your target is, you will be able to shoot it quickly and accurately. There are different ranges that laser light combinations offer and all you have to do is choose the one that gives you the range you need for your shooting activities.


Your use of gun lights will play a role in choosing the best gun lights. Is it for carrying markings or for law enforcement? Military troops, police officers, or other law enforcement officials?

Those who use handguns for hunting or home protection still need something sturdy and dependable, but durability and reliability should not be the primary considerations.

Meanwhile, tactical flashlights with various light modes, including laser, will be prioritized for battle and target destruction duties. You can select lights with medium illumination and led light to view close targets if you’re using them for self-defense.


The material used to construct the light is crucial to consider when it comes to durability. The more durable the material used to create the product, the longer it will endure and work for a longer time. Durable lights are typically more expensive, but the initial investment is well worth it given the light’s quality.

The Glock 19 is without a doubt one of the best concealed carry firearms of all time. The Glock 19 has established itself as a popular contemporary firearm due to its excellent mix of durability, dependability, and lethality. With the compact and affordable design, you get one of the most popular guns of all time.
