You’ve got a TON of options when it comes to Glock lasers. Our ultimate guide to the best laser sights for your Glock will hopefully point you in the right direction.

The reason I was initially attracted to Glock pistols was simple: I was regularly told that the Glock 19 was one of, if not the most, popular handguns in all of history. The Glock 19 featured a number of impressive changes, some of them sorely needed, including new barrel rifling and ambidextrous slide stops. The flared magazine well was also a welcomed addition to the handgun, and the public seemed to agree, with the Glock 19 rapidly climbing the list of best-sellers in America. It’s also one of the most popular Glock models that people like to put laser sights on as well.

Sometimes, however, a handgun by itself just doesn’t pack enough of a punch or have enough luster to make it worth your while. While I loved my Glock 19, I quickly found myself less than satisfied with its iron sights, and figured I needed to make a laser purchase if I wanted to get serious about my accuracy and precision. There are so many options to choose from, however, that I was initially put off of a purchase entirely because I simply couldn’t pick the right one.

What to Look for in a Glock Laser Sight

Let’s get started. But first, we need to know what to look for and why in Glock laser sighting systems.

The right laser sight can make all the difference when you’re out on the range shooting targets or exploring the woods in the pursuit of prey. The problem is that the differences between the right laser sight and the wrong one for your Glock pistol aren’t always easy to discern. As a matter of fact, I once struggled when it came to finding the right laser sight for the job, and wished I had some help.

Here’s everything I’ve since learned about choosing a laser sight for a Glock pistol, and what common mistakes I think you should avoid if you don’t want to end up regretting your purchase.

Fit and Finish of Glock Laser Sights

Nobody wants a quarter inch of plastic hanging off their Glock or a laser housing that isn’t quite the right color in comparison to the frame of their Glock pistol.

There are quite a few cheap lasers out there that just kind of hang off of your picatinny rail and then there are some that fit nice and flush and just “feel” like their quality.

You want the latter. This also makes a difference when we’re talking about how your laser-sighted Glock will fit into a holster, but that’s another topic.

Reliability

Glock makes some of the most reliable handguns in the world, your laser sight needs to be reliable as well. First and foremost, your Glock laser needs to be able to handle the recoil of your pistol.

I’ll tell you right now, not every laser sight out there can withstand continuous vibration from 9mm fire and still work every time.

Brightness of the Laser

A dim laser is absolutely useless for your Glock. Especially if you carry one everyday. Generally speaking, green lasers will be much brighter than red lasers as we discussed in our red vs. green laser sights article. If you’re using it for EDC (every day carry), you should be using a green laser sight for your Glock carry pistol.

 

 

Red vs. Green Laser Color

The first question I encountered was the simplest, and it’s one you’re going to have to deal with, too; do you want a red laser sight, or a green one? Some gun nuts passionately argue that there’s a major difference between red and green sights, but I think it’s really a matter of personal preference. Nonetheless, there are reasons to believe that green lasers take more energy to generate, and in turn appear more visible to the human eye in low-light conditions.

This has the consequence of making many green laser sights more expensive than some of their red counterparts. If you’re really going for maximum visibility, it’s likely worth spending the extra few dollars for a green sight that can peer further into the darkness and pop out more vibrantly when you’re searching for your target. If you’re looking for a cheap option that will improve your overall visibility but don’t care too much about the specifics, a cheaper red option will likely suit your Glock pistol better than a green one.

Regarding battery life, I also discovered that red sights typically last substantially longer than their green peers because of the energy differential needed to create the two different colors. This also means that red lasers have a greater ability to deal with temperature variations than green sights do. If you’re a shooter who’s going to be exploring cold areas alongside of hot ones, it’s worthwhile to invest in a red laser sight for your Glock pistol.

Colorblindness is also something to take into consideration; a close friend of mine enjoys shooting, but suffers from deuteranomaly, otherwise known as green colorblindness. It’s the most common form of color blindness and can diminish your ability to use certain sights. As always, be sure to test before making a final decision if you can.

Indoor vs. Outdoor Use

Certain colors perform better indoors versus outdoors, too, which you need to take into consideration depending on where you’ll be shooting. Red laser sights are popular for indoor shooting environments, largely because they can be very challenging to see in high-light environments like a sunny field. Even relatively cloudy days can still emit enough sunlight to diminish your ability to peer down a red laser sight with ease. Well-lit conditions traditionally call for a vibrant emerald-green laser sight, as this will be much more visible on a bright day than a red sight.

There’s a serous difference in how far red and green sights reach, too. Most red laser sights will be unsuitable if you’re trying to hit a target further than 30 or 40 yards away, for instance, whereas green lasers will give you a much brighter picture at up to 100 yards. Similarly, I’ve always believed that green laser sights are less durable than their red counterparts and don’t hold up as well to the natural wear and tear that your firearm will experience when you visit the range.

Pointability and Holstering

Upping the pointability, or the capacity of your handgun to serve as an extension of your hand and eye coordination, is the most important aspect of purchasing a laser sight for your Glock pistol. I found that the vibrant laser I eventually settled on helped me locate my targets better, especially in low-light conditions, and that my eyes naturally arrived on the sights with much greater ease than they had when I was using iron sights. The size, length, and weight of your laser sight could impact your Glock pistol’s pointability, so be sure that a small adjustment to your sights won’t throw off your shooting.

Besides pointability, you also need to consider how you’ll be holstering your weapon. Far too many gunowners I know made an expensive purchase, waiting eagerly for it to arrive, and then found out that their new laser sight prevents them from holstering their firearm in the holster they’ve been using for years. Bulking up your Glock pistol with a new addition isn’t always fun, but sometimes you’ll need to make a sacrifice in order to get a new laser sight. Consider the possibility that you’ll be forced to purchase a new holster if you purchase a laser sight before you end up finalizing your purchase.

You should also take some time to consider the other gear you use in tandem with your beloved Glock pistol. Sights which are easily affixed but hard to remove may require you purchase a new carrying or storage case, for instance. Similarly, gunowners are famous lovers of attachments of all shapes and sizes, so consider how your new Glock pistol laser sight will meld with your existing flashlight if you have one.

Read Reviews About Glock Lasers You’re Interested In

Finally, you should review the advice and reviews of others who have previously bought the laser sight you’re seriously considering. You can find plenty of reviews on YouTube for just about any firearm or firearm-related accessory, and Glock pistol laser sights are no exception. These videos aren’t only useful because they act as comprehensive user reviews but are also handy because they effectively serve as a tutorial for how to properly mount your Glock pistol laser sight once you’ve made a decision.

I always recommend price comparisons so that you don’t get ripped off, but don’t be afraid to splurge a little extra for a green laser sight. My first laser sight had an admirable red shade, but I simply found it too lackluster in outdoors environments to be that useful. Gunowners who exclusively shoot at indoor ranges may find a red laser sight and its higher versatility and lower price to be the more attractive option, but those who love the great outdoors will likely need a green option.

What are you waiting for? Start scoping out your laser sight options right away, and soon you’ll be shooting like the professionals with the help of your new laser sight for your Glock pistol.

Our Top Ranked Laser Sights for Glock Pistols

We’ve chosen our top 3 picks for Glock laser sights. All of these are very well reviewed, have an average rating of over 4 stars and are quality built to work reliably on your Glock pistol.

Without further delay, here are the best laser sights for Glock below.

TOP PICK: Crimson Trace Laser Grip for Glock

Having owned these laser grips for both my G17 and Glock 19 handguns, I know that these are the best laser sights on the market today. No on/off switch, no fumbling around. You just place your hand on the gun normally and you’re ready to go.

One of the best things about the Crimson Trace laser grip sights is that installing them on your Glock is so easy. All it takes is the replacement of a stock grip pin with the slightly larger Crimson trace pin (to accommodate the grip laser) and you’re done. It takes all of 5 minutes to do. Plus, the grip laser sight frees up your Glock’s picatinny rail for a nice light (we recommend the Streamlight TLR-8).

Some people don’t like that the grip laser makes your Glock’s grip a little bit bigger. I disagree with that. My hands are pretty big and I actually get a more positive grip on the gun with the Crimson Trace laser attached (on a Glock 17). I could see how the laser grip might help people with bigger hands grasp the smaller Glock 19 as well.

Crimson Trace Laser Grip Laser Sight Video Review

Here’s an awesome overview video of the Crimson Trase laser grip sight for Glock. The firearms instructor in the video goes over why he likes laser sights and what the Crimson Trace lasergrip has to offer.

LaserMax Guide Rod Laser for Glock

Although I don’t own this laser personally, several of my buddies own these guide rod laser sights for Glock and absolutely swear by them. I think I know what they mean.

One thing about owning a laser sight for any handgun is the fact that you’re going to need a different holster because the sight won’t fit in most conventional holsters.

Another problem is that once you have the rail mounted laser installed on your Glock, you don’t have any room for a light because your rail is taken up. The LaserMax guide rod laser takes care of both of these issues (to be honest, the Crimson Trace mentioned above does too).

The following video by Colion Noir (pretty good YouTube gun channel) explains his thoughts on buying a Glock 27 and being surprised to find the Lasermax guide rod laser installed.

It is a little pricy though (around $300 for the LaserMax) but it seems to be a great laser for your Glock. I have to rank it #3 on this list since I don’t actually own it but I have several very trusted friends that love it. The reviews for this guide rod laser sight are also pretty good on Amazon.

Viridian C5 Universal Sub-Compact Laser Sight

You know what Viridian makes? Laser sights. In fact, they make some of the best in the world. The Viridian C5 is a very well constructed compact laser sight that’s going to fit basically any Glock you own very snugly.

The laser on this thing is basically brighter than you’ll ever need, but you want it anyway. It’s got a 5mW peak laser brightness – extremely bright. So bright that you could see the dot for miles at night. During the day, it’s still very bright.

We highly recommend the Viridian C5 because it’s probably the best laser sight you could buy for a sub-compact Glock.

When you’re betting your life on a laser sight to work (CCW), I’d bet on this one.

Which Laser Sight is Right for Your Glock?

In this post, we’ve gone through 3 different laser sights for Glock. Surprisingly, they’re not all rail mounted lasers either.

Keep in mind what features are most important to you in a laser sight for your Glock and choose accordingly. We think the three mentioned above are definitely the best laser sights for Glock on the market.
