Best Light for Glock 19: Here’s Your Ultimate Guide 2022

Do you want to accurately focus and see your target even in the darkest surroundings? Well, that’s definitely why you should be extremely careful in choosing the best light for Glock 19.

And since I’ve been shooting for quite a while, I’ve tried a bunch of weaponlights, each with specific useful features and performance levels. So I basically recognize and understand what works and what doesn’t.

For a Glock 19, which is undoubtedly the best selling handgun in the world for its home and personal defense reliability, it sures needs an equally good light for Glock 19 Gen 3, 5, and so on. It has to be solid, topnotch, and durable to ensure longevity and superb performance.

In today’s guide, I’m reviewing the top 10 picks for your reference when comparing different options. I’ve also answered the most frequently asked questions and discussed some important points in choosing a pistol flashlight and laser (red laser light or green laser sight) combo. So let’s get to it.

What should I look for in a pistol flashlight?

Choosing the best pistol light for Glock 19 may be time-consuming and challenging given the number of options out there.

Select one that is reliable and has an excellent reputation among tactical and military professionals. Cheaper is not always better. Strike a balance between price and quality.

Next, check the lumens that measure how bright or dim the light is. Too much of it is not always better. A bright light can blind an attacker, but it can blind you, too, especially if you’re indoors. As much as possible, you might want to go between 200 and 400 lumens, although 800 lumens may be ideal for outdoor and hunting.

How many lumens should a pistol light be?

An EDC light with between 300 and 1000 lumens should be sufficient. Too much brightness, again, isn’t always a good thing especially if you’re using it indoors. A very bright light will reflect off of windows, mirrors, screens, and bright walls, destroying natural night vision and making seeing extremely challenging.

Meanwhile, an ultra compact handgun light with a higher lumen will be ideal for its additional brightness and range that will let you see further to identify targets easily. Using a too low-powered Glock 19 gen light may hinder your ability to establish positive identification of the target.
