Glock 27 Gen 4 Sights

Sights types

 

Many people say they’d want to have a cat’s life, because they could sleep all day. If I was ever to become a cat, it would be for its ability to see in the dark. Night vision is an important feature for many gun owners, especially those who often find themselves in tactical situations. One of the solutions to this issue are night sights, at which we will have a closer look now.

Types Of Night Sights

Night sights are small optic devices that are most frequently installed on the rear and front end of your handgun. They are designed to enable you to see better in low light situations and also enhance your accuracy. The night sights come in more versions – Photoluminescent nights sights, Tritium nights sights, fiber optic nights sights. What’s a great plus of these sights is the fact that compared to, let’s say, red dot sights, night sights are much more compact, less noticeable, thus more ideal for your everyday carry.

Photoluminescent Night Sights


Photoluminescent night sights for the Glock 27 Gen 4 transform low-light shooting, absorbing light all day to emit a bright glow in darker conditions, enhancing target visibility for Glock 27 Gen 4 users. These sights eliminate the need for batteries by harnessing natural light, making them ideal for rapid target identification in self-defense scenarios. Easy to install, they provide an immediate upgrade to the Glock 27 Gen 4's sighting system, boosting confidence in shot placement regardless of lighting conditions.

Their effectiveness, however, depends on prior light exposure, potentially limiting their use in unexpected low-light situations. Over time, the sights may require recharging with light to keep them glowing brightly. While they offer significant advantages at dusk or dawn, their performance in total darkness doesn't compare to tritium night sights. Still, for Glock 27 Gen 4 owners, photoluminescent night sights offer a low-maintenance, cost-effective solution to improve night shooting without the need for electronic components.

Pros

No Battery Required

Enhanced Low-Light Accuracy

User-Friendly Upgrade

Cons

Light Exposure Dependency

Glow Intensity Diminishes

Limited in Complete Darkness

Tritium Night Sights


Tritium night sights are a game-changer for Glock 27 Gen 4 owners seeking reliable, low-light targeting capabilities. These sights utilize small amounts of tritium, a radioactive isotope, to provide a consistent glow without the need for external light sources or batteries. This makes them an ideal choice for self-defense scenarios, where quick target acquisition is critical, regardless of the lighting conditions.

The glow from the tritium is subtle yet clear, ensuring it does not overpower your night vision or distract from the target. Unlike photoluminescent sights, tritium night sights do not require "charging" with light, offering unwavering performance through any situation. Their robust construction also means they are built to last, often matching the lifespan of the firearm itself. For Glock 27 Gen 4 users, tritium night sights are an excellent investment for enhancing shooting accuracy and confidence in low-light environments.

Pros

Self-Illuminating

Durability

Improved Accuracy

Cons

Higher Cost

Non-Replacable Tritium

Limited Brightness

Fiber Optic Sights


Fiber optic sights are a popular upgrade for Glock 27 Gen 4 enthusiasts looking to improve their target acquisition speed and accuracy in varying lighting conditions. These sights capture and channel natural or ambient light to their ends, creating bright, easy-to-see dots that dramatically enhance sight visibility. Unlike tritium or photoluminescent sights, fiber optic sights shine brightest in well-lit environments, making them particularly advantageous for daytime outdoor shooting activities.

The vibrant colors available for fiber optic sights—typically red, green, or yellow—allow for quick eye alignment and target focus, facilitating faster and more confident shooting. Installation on the Glock 27 Gen 4 is straightforward, offering a simple yet effective modification that does not alter the firearm's balance or handling. While they do not glow in the dark like tritium night sights, their high visibility in daylight can significantly improve shooting performance during the day. For shooters participating in competitive shooting or who frequent well-lit ranges, fiber optic sights on the Glock 27 Gen 4 offer an unbeatable combination of visibility and precision.

Pros

Exceptional Daylight Visibility

Variety Of Colors

Easy Installation

Cons

Limited Low-Light Performance

Durability Concerns

Dependence on Ambient Light

WHY WOULD I GET A NIGHT SIGHT? - BENEFITS OF NIGHT SIGHTS

Even if you aren’t lurking out in the streets at night often, a set of night sights could be a good solution for you, as there are definitely moments when you want to see a bit clearer. Night sights seem to be the right choice for a comfortable carry of night sights around the clock. These tactical and everyday night sights have some downsides, but advantages outweigh them anytime. In general, the biggest advantages of night sights are considered the following:

  • Accurate shooting in low or even no light situations
  • They are compact in size and ideal for everyday carry
  • Can work as an upgrade over factory sights
  • Longevity of tritium sights
  • Come in different colors – green, red, yellow
  • Can be used in daylight - they are not only meant for night
  • Help you find your gun quicker in a low-light environment
  • They don’t require difficult installation

No matter how you rank these benefits importance-wise, but it’s obvious that if you are looking for better visibility at night or simply in darker environments, night sights are a great and fairly affordable option for you. They won’t weigh your gun down by much and they will grant you better target acquisition and overall gun confidence in situations that are not that bright. Although they might get a bit pricey, if you go with the trusted brands, you’ll definitely not regret it.

How To Mount A Night Sight

Night sights installation is fairly simple. Although most people choose the easier way and go to their local gunsmith to have their night sights installed, you can definitely. However, if you are comfortable with tools and simple machinery, the job is not difficult and fairly straightforward. Well, of course it’s better if your hands are nimble and skilled at at least the basic workshop operations. Let’s have a quick look at what you’ll go through if you have a go at mounting a night sight set for your gun.

If you own, let’s say, a Glock, you will first need to get a set of glock make-respective night sights. Once you get hold of them, there will be a couple of other tools you will need. You’ll definitely need a table vise. Don’t be afraid if you’ve never worked the tool, a session or two will give you the basic understanding of it. You need to disassemble your glock first, but be safe about it, please. Night Fision, another night sights oriented gun accessories company, advises to apply their and other night sights to Glock aftermarket slides ready for applications, which have been growing in popularity lately. So if you get one of those too, even better.

You will need a punch, hammer and table vise, perhaps some sanding the material down too. Before you start, make sure the slide and the sights are cleaned well. The rear part of the set should slide in from some part easily and then you will need to apply some force with a hammer to get it in. If you have a problem pushing this part into the slide, you might need to file it down with sanding material. Although you will need quite a lot of force to slide the sight in, try to be gentle. The other part of the set, the suppressor sight, is attached to the front of the slide. Its application is fairly easier than the rear sight part. You need to glue it in, for example with Locktite, and then hand tight the screw inside of the sight with a fitting driver. Make sure you apply appropriate force, you don’t want to overdo it and perhaps even damage the pieces. After some time the parts should properly settle in and you’ll be good to put your gun back together. This was put in layman terms, but if you want a more precise guide on how to install a particular night sight on your gun, there are many video guides out there. I’m sure you won’t have any real trouble improving your gun optics at home.

Sight Alignment & Accuracy Tips


Aiming your Glock 27 Gen 4 correctly is a thing you have to master in order to perform better. The major keys to aiming and effective target hits are properly aligned sights, proper sight picture and little movement while you are on target. The hat of the battle or any dangerous situation may cause your aim to be worse, but practice makes perfect.

Aiming consists of two major elements, sight alignment and sight picture. The goal is to get the point of alignment equal to the point of impact. Sight alignment relates to the rear and front sight. Simply, the eye must be lined up with the Front and Rear Sights and the sights positioned so that the alignment is correct. Proper sight alignment of the two sights means that the TOP of the Front Sight is vertically centered in the NOTCH of the Rear Sight, so that there is an equal amount of white space on either side of the Front Sight post. It also means that the TOP of the Front Sight is LEVEL horizontally with the TOP of the Rear Sight. Of course, there are many different types of sights, but this general alignment concept works for all types of sights whether the front sight is a blade or a small or large dot and whether the rear sight is an open sight, two dots, U-shaped, V-shaped, or a simple notch in the back of the slide. No matter how the sights are configured, the front sight is designed to be placed on the same vertical axis as the rear sight.

Errors in alignment may be:

  • Front sight too low - low hit on target
  • Front sight too high - high hit on target
  • Front sight skewed to right - right hit on target
  • Front sight skewed to left - left hit on target

Don’t forget to use your eyes. This may sound silly, but using your eyes properly (using the dominant eye) is a key figure. The NRA suggests that it’s best to shoot with both eyes open. Sometimes of course, you get better results with the use of your dominant eye.

How To Determine Your Eye Dominance [In 6 Steps]


Sight Picture is the placement of the properly Aligned Sights on the Target. This is a short and throrough guide that you can use while determinig your dominant eye and thus improving the performance of your Glock27 Gen 4

  • Extend both of your arms and hands forward as in your preferred shooting stance;
  • Place your hands together to make a small triangle between your thumbs and first finger of each hand slightly overlapping your fingers; your thumbs will form the base of the triangle;
  • With both eyes open, look through your triangle while your arms are extended and focus on the bullseye of a target or some similar object in the room and put it in the center of your triangle;
  • Now while looking through your triangle, close your left eye. If you see the bullseye or object centered in your triangle, you are right-eye dominant. But if the bullseye or object moves away from your view to the left and you can’t clearly see it, you are left-eye dominant;
  • To validate your eye dominance, look through your triangle again and center the bullseye or object with both eyes open; close your RIGHT eye this time and if it remains in view, you are left-eye dominant. But if it moves away from your view to the right, you are right-eye dominant;
  • To further validate your eye dominance, repeat steps 1 and 2 above, then with both eyes open bring your triangle straight back to your face; you will naturally bring it back to your dominant eye without thinking

If you are a right-handed person but your left eye is your dominant eye you don’t need to worry. The simple and effective trick is to move your head slightly to the right while aiming. You can then better align your dominant eye with the sights.

Once you have your Front and Rear Sights in the proper relationship to each other, the question then is “Where do you place the sights in relation to the target?” What is the “Sight Picture?” Do I put my Front Sight in the middle of the bullseye, at the bottom of the bullseye, at the top to cover-up the entire bullseye, or where? The answer is it depends. Guns which are sighted in for a Combat Hold mostly require the shooter to place the Front Sight where it covers the exact center of the target (Center-Mass Hold), while guns sighted in for a Target Hold usually get their accuracy when the Front Sight is aligned at the center of the bottom of the bullseye (Six-O’Clock Hold.) Self-Defense handguns usually (not always) use the quicker but less precise Combat Hold. There are several variations and personal preference plays a key role.
