Are All Sights The Same?
If you’re talking about size and compatibility - yes, they are. All the pistols in the Glock series share the same dimensions for sights, except for Glock 21, 27, 42, and 43. However, in this article, we’ll be focusing on Glock 19, 26, and 27, so you don’t have to worry about size. All sights in this review will just fit together really well with those specific Glock models.
Having good sights on your handgun greatly helps in every situation and for every person, no matter if you are a rusty youngster or an experienced shooter with a pair of old eyes.
But, when it comes to the features, all sights are definitely not the same. There are several different types of sights which can be mounted on a handgun. These can be basic iron sights, illuminated sights, reflex sights, red-dot sights, or laser sights.
For instance, an illuminated sight lets you aim at your target almost instantly and without fumbling, since you have those illuminated dots as reference points. On the other hand, a reflex sight gives you a focused sight picture and the red-dot sight has an aiming point to make aiming easier. Similarly, a laser sight projects a laser beam for quicker and more precise target acquisition.
Conclusively, the more complex a sight is, the easier it is to acquire the target and shoot. But eventually, it all depends upon what you are comfortable with.
Aspects to Consider When Buying a Glock 19, 26, 27 Sights
Glocks 19, 26, and 27 are pretty compact handguns. They were initially designed to be used as a concealed or backup handgun. Choosing the right sight for your needs requires some contemplation on some very major aspects that really make a huge difference. Let’s consider them one by one:
Durability and Reliability
As with any other product, the first aspect to consider before buying new sights is their durability and reliability. The sights made from metal are preferable over polymer since they have a longer life span along with the ability to withstand the recoil of your weapon. Metal sights can handle extreme pressure and temperature as well, which makes them a good choice for Glock handguns. Plus, since Glock handguns are made from polymer, for the most part, metal sights won’t add much weight to them.
The next thing to consider is functionality. You must decide your intended use and level of comfort before buying a sight. With an illuminated sight, the lamp must be bright enough to let you aim accurately in the dark. Similarly, if you have a battery-operated reflex or red dot sight, it must have a good battery life. A proper check of the functions and abilities of the sights ensures that the accuracy of your weapon will not be compromised. Otherwise, there’s no point in replacing the sights.
Size and Compatibility
The size factor refers to the size of the sight and the dot. Since the point of focus is on Glocks 19,26, and 27, the sights on any of them can be replaced with another. Plus, the sight must be the right size so it doesn’t protrude or interfere with holstering. If the dot is illuminated, it must be large enough to be seen easily, even under low light.
Ease of Use
Finally, it all boils down to the ease of use. There are different types of Glock sights available on the market. Different sights have different aiming systems, such as the three dot, two dot, i-dot, and u-shaped sights. Each of them has its own pros and cons, along with the respective situations they are good for. Some sights, such as the laser-based ones, run on batteries, so you have to keep track of the battery’s power.

Note: Check the Glock for safety. Remove the magazine and ensure the gun is empty.
- The first step is to disassemble the Glock so you are left with only the slide.
- Now use the nut driver to screw out the front sight. Next, replace it with the new front sight, and tighten the screw back into place.
- Place the slide on a vise, so it faces upwards.
- Now, use the nylon hammer to tap and push out the rear sight sideways. This is the place where you might feel the need for a pusher tool.
- Finally, put in the new rear sight and tap it all the way down using the nylon hammer. Check if the sight sits exactly in the center. If it does, you’re done.

People Also Ask
Some people reading this might be new to the topic of sight replacement. Or you might have some questions about these sights. We have compiled an FAQ section to give you an insight into the most common questions.
How Long Do Tritium Night Sights Last?
Tritium has a half-life of 12 years. Which means that tritium sights last for almost 12 years. But it is important to note, that the brightness of tritium decays with time. So such a sight will not be as bright in the tenth year as it was in the first. However, the difference is not very considerable for the first eight years.
How Do Tritium Night Sights Work?
Tritium is a radioactive isotope of hydrogen. However, it isn’t hazardous until swallowed. Tritium decays slowly over time, during which time it releases energy in the form of light. Hence, tritium is a self-glowing element and doesn’t require electricity or sunlight to glow. Tritium night sights contain small vials of tritium which emit light constantly.
How Do You Adjust a Glock Rear Sight?
Adjusting the Glock rear sight can either be done with a sight pusher tool or with a nylon hammer. You just have to align the sight to the exact center of the slide. You can mount the slide on a vise and use the nylon hammer to tap it down into position.
How Do You Use Glock Sights?
To use simple iron Glock sights, you have to align the front and rear sight in such a way that it makes a W. If it is a three dot sight, all the three dots must be at the same level and the target should be exactly on top of this W. For red dot sights, the aiming point is the red dot.
What Are Night Sights?
Night sights are usually iron sights of a pistol which have tritium inserts inside. These sights glow in the dark and help the shooter with aiming at the correct point. Such sights are especially helpful for low light conditions and for older people.
