How to replace Glock sights?

It depends on the type of sights that are being replaced.

If they are fixed or adjustable sights, then a gunsmith will need to be contacted to remove and replace them.

If they are fiber optic sights, then they can be replaced by the user without any special tools or skills. Simply remove the old sight from the slide and install the new sight in its place. Make sure that it is properly aligned before using it on the range or in a tactical situation.

You must use the correct tools and have a firm understanding of how the Glock sight system works to avoid damaging your pistol.

1. The first step is to remove the slide from the frame of the pistol.
2. Next, use a screwdriver or other tool to remove the screws that hold the old sights in place. Be careful not to lose any of these screws, as they are small and easily lost. Once the screws have been removed, gently pull on the old sights until they come free from the slide.
3. Next, install the new sights by reversing these steps. Make sure that the new sights are properly aligned before tightening the screws. Once the new sights are installed, reassemble the pistol and test-fire it to make sure everything is working properly.

We also recommend watching a video about installing Glock night sights without a scope pusher:

If you have a standard Glock, there are three types of replacement sights that you can get: night sights, fiber optic sights, and tritium sights.
Night sights are the most popular type of replacement sight, as they allow you to see your target in low-light conditions.

 
Fiber optic sights are becoming increasingly popular because they allow for faster target acquisition.

While tritium sights are ideal for people who want the benefits of night sights without having to sacrifice daylight visibility.
To install any of these types of replacement sights on your Glock, you will need a sight pusher tool and a vise. First, remove the old sight with the pusher tool. Then secure the gun in the vise and use the sight pusher tool to install the new sight. Be sure to follow the instructions that come with your sights, as each type of sight may have different installation requirements.
