Why Bother With Laser Sights?

The 6 Best Glock 19 Laser Sights in 2021 Gun Pointed at Someone

Many of us keep our pistols for protection. However, a pistol will become reliable only if we practice using them. This is where aiming, and laser lights come in. Laser lights enable you to shoot efficiently whether you’re crouching or lying down. Moreover, it helps you aim well during the dark. Sure, you can see clearly using your sights during the day, but it’s a different setting in low-light situations or at night.


However, laser lights do pop even in harsh daylight. Overall, laser lights provide benefits that using only iron sights cannot provide.

If you’re someone with vision issues and need to train, then laser sights would help with shooting. In addition, if you think you will have to use your pistol in compromised situations, it will be a lifesaver. In short, we can all use it under different circumstances. 

Don’t get me wrong, laser sights will not make you an accurate shooter in an instant. It does, however, improve your skills in the long run. And in conditions when light is not your greatest ally, that laser might be the ultimate game-changer.

Laser Lights Pros and Cons

Pros
  • Low-light advantage
  • Faster sight acquisition
  • Improves accuracy
  • Target engagement even in unideal positions/ while moving
  • Serves as a training guide
  • Helps shooters with poor eyesight
  • Can deescalate a heated situation
Cons
  • Can reveal one’s location
  • Can make a gun bulkier
  • Batteries run out
  • Holster adjustments

Laser sights are not perfect, they also come with their own cons. One of which is that they can give away your location. While it’s true, the laser paths are not visible most of the time, contrary to what’s often portrayed in the movies. We can only see the beam when there’s smoke or fog, which isn’t often the case in real life.

The dot is only seen from the source and on the target so being on the move helps when you are in a gunfight. You also have to be aware of the situation and only turn it on when needed. 

The same can be said with the issue of batteries running out. Most of the things we use, like our mobile phones, run on batteries. It’s a fact, batteries do run out, but should we stop using them despite the benefits these things give us? I don’t think so. 

The Downsides…

Laser sights can make your handgun bulkier. However, that also means finding a holster that will fit it can be a problem. It really isn’t much of a concern nowadays. Laser sights have become increasingly popular and are becoming a common fixture on pistols. In addition, holster brands are seeing this trend and are providing more flexibility on this. Most often, you can find one that fits your Glock such as the SuperTuck IWB Holster and the Freedom Carry IWB Holster.

The downsides of laser sights are manageable. They need adjustments, it’s true, but if it brings more security then I’m all in. After all, we’re talking about life and safety here. 

Laser Sights vs Red Dot Sights

Laser and red dot sights are two different optical aids for shooting. While these two serve similar functions, they are different in many ways.

Laser sights simply work by projecting a dot on the target. You can use it without aligning your eye to the sights. This is especially useful when you’re in compromised situations. Because of the projected laser, you can focus more on the target at hand. 

Red dot optics are another device that helps with our point of aim. The dot is produced by an LED light reflected on a curved mirror. But unlike the lasers, these things get in the way of the iron sights. It can restrict you from switching between the two if you want the iron sights as a backup. 

As the name says, we have to focus on the red dot as we aim. This dot can come in different sizes, called minute of angle (MOA). The smaller the dot, the more accurate the shot can be. But also, since it is smaller, it can be hard to see. Like everything else, it calls for familiarity and preference.

Another thing that makes red dots different is that you, the shooter, are the only one that sees them. It is not projected on anything and so, it does not reveal your position. This sight, however, still requires you to aim and focus on the sight rather than directly on the target. 

The Best Glock 19 Laser Sights Compared

Laser sights come in different designs and placements. We can attach them on our pistol’s trigger guard, rail, grip, and even internally, through the guide rod. So many of them are available on the market so there’s no shortage of options for different preferences. 

Our 6 best Glock 19 laser sights come in all these varieties. Each has distinct designs, which may be interesting to others and unappealing to some. We will dive deeper into their specifics and why they made it to this list. And of course, since this is not rainbow land, we will also take a look at the pros and the cons to balance things out.

Crimson Trace Laser Grips

The Crimson Trace LG-639 fit Gen 3, 4, and 5 of Glock 19. It has a unique and ergonomic design that comes in both red and green. As the name says, you need to install it on the grip of your Glock instead of under the barrel or on the rear. It’s made of a combination of polymer and rubber for comfort.

Two 2032 batteries (included) provide up to four hours of continuous laser light. Their small size allows you to place them on both sides of the grip, for a slim design. One thing we like about it is that it is easy to install and very user-friendly.

Lasergrips use an instinctive activation mechanism that lights up immediately upon gripping. Both the red and green lasers put out 5 milliwatts of a powerful laser.

The unique design of the Lasergrips allows you to protect the laser components at all times. You don’t have to worry about bumping it into something since you are basically holding it.

This option doesn’t exactly come cheap. Also, if not used to, you might need to adjust to the laser placement. Since the laser positions itself along the slide, we might need to adjust our pointer finger in order not to block it

Still, there’s very little to complain about these Lasergrips. It’s instinctive and convenient as a whole. If you prefer installing laser sights over the trigger guard, you’ll be out of luck on that part. Still, we find that a laser that activates as you grip is much more ideal.

Pros
  • Unique grip design
  • Convenient
  • Made of comfortable materials
  • Holstering is not affected
Cons
  • Premium price
  • Grip design and laser placement may need adjusting

LaserLyte Rear Sight Laser

The LaserLyte Rear Sight Laser is universal amongst all Glocks. It’s a compact and lightweight laser you can install on the rear of your Glock 19. Though it seems small, it is actually made of heavy-duty high-carbon steel.

This laser can be in steady or pulsating mode. Additionally, the blinking makes it easier to see and you can easily see where you’re pointing at. You can activate this laser sight with an ambidextrous on/off button. It also automatically shuts off after six minutes. LaserLyte provides a one-year limited warranty for this product.

It has a minimal design and simply gets the job done for you and your pistol. We like that the compact size and weight (1.2 oz) don’t interfere at all with any other part of the Glock. You can readily draw without damaging the laser sight or knocking it around. And since it is placed at the rear part, it lets you keep the same holster. 

I also heard about others having some issues with screws and adjustments with this sight. Most of the time this has something to do more with installation (and if you actually read the manual). Windage and elevation adjustments primarily depend on what you’re most comfortable with. And also, it’s our responsibility to check it from time to time in case of loose screws.

It’s important to keep in mind that this is a cheaper laser compared to other products on this list. It probably has a short lifespan since the warranty is only for a year. Still, if your needs are basic, this is a handy little accessory to add to your Glock. 

Pros
  • Budget-friendly
  • No interference
  • Easy-to-use design
  • No need for additional Glock/holster modifications
  • One-year warranty
Cons
  • Possibility of loose screws
  • Adjustments can be a challenge
  • May have a shorter life span

Viridian Reactor 5 Laser Sight

The Viridian Reactor 5 makes it a great choice for CCW, thanks to its small frame. The red laser uses a 635-650nm wavelength. It is one of the brightest dots legally available to gun owners on the market. The green version has 510-532nm for precision targeting. It operates in both constant and strobe mode.

A great bonus is that this laser comes with an Enhanced Combat Readiness (ECR) holster. This hybrid holster automatically activates your Viridian Reactor 5 whenever you draw it. In the same way, the laser light is turned off when it’s reholstered. The holster is made of a glass-reinforced nylon shell and comfortable leather. It’s worn outside the waistband (OWB).

If you’re a fan of Viridian, then you’ll be sold to this laser sight and holster combo. That is if you want an OWB holster for your concealed carry, which will limit some of its buyers. If you already own a perfect holster for your Glock 19, the Reactor 5 probably isn’t the best choice on this list. Otherwise, we have nothing but wonderful things to say about this laser sight.

The Viridian Reactor 5 is a bit more expensive than the previous option in this list. If you’re willing to pay the price, then you’re making a good investment in this laser. Remember that you’re getting a top-of-the-line laser with a holster for that price. This combo may not be for everyone, but it’s a great deal if you were looking for a holster anyway. 

Pros
  • High tech laser
  • Comes with an ECR instant-on hybrid holster
  • Compact size and weight
Cons
  • Limits buyers with required OWB holster

LaserMax Guide Rod Laser Sight

The Guide Red Rod Laser is made of aircraft-grade aluminum (like most high-quality scopes are). It comes with a Wolff spring replacing the stock guide rod on your Glock. The body of the laser will only add a couple of ounces to your gun’s total weight.

Options are available for all generations of Glock 19. The LMS-1131P fits Gen 2–3, LMS-G4-19 for Gen 4, and LMS-G5-19 for Gen 5. These lasers can also come in green color. In addition, it only takes a couple of minutes and you can do it yourself at home, no gunsmith needed. This laser has a constant and a pulsating light mode.

The fact that it doesn’t change the look of your Glock, unlike exterior lasers, is a sure advantage. Every accessory you attach to your pistol makes it a little less compact. Most ideal though is that installing the laser is super easy and done in a couple of minutes. Though, you might want to give it more attention while doing so since it involves the internals.

The only big catch on the LaserMax Guide Rod Laser is the fact that it is in the higher price range. It’s a viable option, there’s no doubt about that. It does exactly what it needs to, and it should last quite a while since all the components are internal.

You can get the:

Pros
  • All internal components
  • The Glock remains snag-free as it is
  • Does not interfere with holster, grips, or lights
  • Easy installation
Cons
  • More expensive than other competitors
  • Might make the Glock less compact

Crimson Trace Rail Master Universal Laser Sight 

The Crimson Trace Master Universal Laser (CMR-201) is a 0.2-pound device attached to the accessory rail. It is compatible with all Glock 19 generations, including Gen 4 which often has a challenge finding a fit.


The Class 3R laser of this sight emits 5 milliwatts of laser. It is one of the brightest dots available to gun owners on the market for precision targeting. It operates in one 1/3N battery which is included in the box.

You can activate it from both sides as it has an ambidextrous paddle switch. You may have to purposely reach it though, unlike the instinctive CT Lasergrips version. This switch makes the laser a bit wider so you may have to make adjustments to your holster with this one.

The universal design of this laser sight is an advantage as it caters to a lot of pistols. However, it can also become its own weakness as it wasn’t made for the Glock 19 in particular. Crimson Trace is a trusted name when it comes to laser sights. The Rail Master Universal Laser is easy to spot and is great at zeroing. With a price that is less than $200, this one is definitely a great buy.

Pros
  • Small and lightweight
  • Easy to install and use
  • Ambidextrous paddle switch
  • Affordable for a Crimson Trace laser sight
Cons
  • Not fitted specifically for the Glocks
  • Need holster adjustments

Souforce Adjustable Laser Sight

The 6 Best Glock 19 Laser Sights in 2021 Souforce Adjustable Laser Sight

The Souforce Adjustable Laser Sight is a very low-priced tool that has both red and green options. The package comes with three AG13 batteries and two wrenches which is a real steal considering the price.

The laser has a metal casing that protects it from wear and tear. It is placed on the Glock rail, like the Crimson Trace Master Universal Laser. It comes with a mounting deck which you clamps on the rail, and that’s mostly it. Due to its universal design, it can be a little loose in some places but can be remediated without much effort.

This is by far the lowest-priced laser on this list. Obviously, most of it has something to do with the fact that little is known about the brand as yet. But does it mean it is far behind in usability? Does not seem so. It has an impressive wall of 5-star reviews from online purchases where it is available.

Souforce Laser Sights are not as popular as the others on this list, but many are satisfied with the product. The laser is decent and simply does the job. If you’re one who does not care that much about the name and is looking to save some bucks, then this is for you.

Pros
  • Super affordable
  • Easy to install
  • Metal housing
  • Includes wrenches and batteries
Cons
  • One-size-fits-all design
  • Relatively new to the scene

Bonus: Laser & Light Combo

Most often than not, aside from laser sights, we also need lights to navigate the dark with our handguns. Thankfully, we don’t need to buy them separately anymore since the two are already integrated. We added one of the most famous laser-light combos available out there to widen your options.

Streamlight TLR-4

The Streamlight TLR-4 is a two-in-one device. It gives you the advantage of shooting in a low-light environment with the laser guiding you. It is specifically made for compact guns like the Glock 19. Additionally, this combination is composed of a C4 LED flashlight, that emits 110 lumens, and a Class 3R laser. It runs in a CR2 battery which includes one in the package.

You can operate it in three modes: laser only, light only, and the laser-light combination. Switching between the three is easy because of its ambidextrous controls. As an addition to your Glock, this one is quite lightweight since it is made of polymer material.

Mounting is easy as you can just hand tight it or use a coin. Though, you might not want to overdo it as it can break the plastic rail attachment. As observed, the laser is slightly way below the barrel, under the flashlight. Even so, adjusting the laser can be very effortless. It quickly zeroes and holds it very well. 

The location of this laser and light combo might need some holster change. Still, the Streamlight TLR-4 is a bang for the buck. It costs below $150, and for a laser and light combo of this quality, it’s more than worth it.  

Pros
  • Affordable price
  • Easy to install and adjust
  • User-friendly/ easy to navigate
  • Great at zeroing
  • Lightweight
Cons
  • Laser-barrel distance
  • Might require holster modifications
  • Might break easily

Conclusion 

All the featured laser sights mentioned have their own advantage, that’s why they made it to the list. But among them, our recommendation would be the LaserMax Guide Rod Laser. Our bias is toward this one since it keeps the Glock 19 as it is. It does not snag and most of all, it has an impressive laser, especially the green one. While our choice has a higher price than the others, we’d like to think of it as an investment. This is the kind of add-on that you can’t really go wrong with.

If you want to go the budget route, the Souforce Laser Sight is a good alternative at only $24.99

  1. Great guide as a laser sight can be one of the most useful handgun accessories. The potential improvement in target acquisition time can be a literal lifesaver.

    But one comment, the power output for these lasers is in milliwatts, not megawatts, as stated in the crimson trace writeup. For comparison, the LaWS laser system tested by the Navy on the USS Ponce, for destroying drones or speedboats, had a max output in the 50kilowatt range, 1/100the power of a 5 megawatt laser.

    A 5 megawatt crimson trace laser grip would be freaking awesome, but having to haul its power supply on a semi would make concealed carry a bit difficult.
