Installing a Glock sight is easy, right? For some, maybe. For others—especially those who have purchased one for the first time—it may be a daunting task. Glock owners across the globe attach sights to their handguns to assist with aim and accuracy. They are extremely important for accurate shooting, both in target practice and in practical scenarios like hunting or self-defense. In other words, a well-installed, well-maintained sight could enhance the effectiveness of your firearm based on the specific needs or use case of the shooter. And who doesn’t enjoy better performance? It’s one of the reasons why sights have become popular among concealed carry enthusiasts. 

So, whether you’re installing a Glock sight for the first time or looking to replace your Glock sight, we’ll break down the proper step-by-step process as well as the benefits of having your sight professionally installed.

Glock Sight Installation

So, you’ve got your new Glock sight ready to go, now it’s time to properly attach it so you can put it to good work at target practice. Because your Glock most likely came with standard-issue front and rear sights, you’ll have to get rid of those. This step involves taking your Glock apart.

To start this process, make sure your gun is unloaded to avoid any accidental discharges. Next, safely eject your magazine and lock the slide back. This will allow you to disengage the firing pin and recoil spring before removing the slide. Once this step is complete, you’ll be ready to install your Glock sight.

Remove Existing Sights

Once you’ve safely taken apart your Glock, you can start the process of replacing your Glock sights. To start, you’ll either need a universal tool, such as a screwdriver, or a front and rear sight tool to remove the two parts of your gun’s sight. Beginning with either the front or rear sight (you can go in either direction), carefully remove the screws to avoid damaging your slide. Once removed, you’ll want to slowly but surely push the sights off of your slide.

Install New Glock Sights

Once you’ve successfully removed your existing sights, you can install your new Glock sights. Place the new front sight in the appropriate hole at the front of the slide. If you’re someone who’d like their sight to potentially last longer, you could apply a small amount of Loctite to the threads of the sight screw. This will help hold your screws in place over time. Then, use the front sight tool to tighten the screw.

The process for the rear sight is very similar. Once you’ve pushed the new rear sight into the slide and centered it, tighten the nuts or screws to secure it in place and get ready to experience your newfound accuracy at the shooting range. That comes after the next step. Let’s not get too ahead of ourselves.

Reassemble Your Glock

Let’s not forget to piece our firearms back together. Once you’ve installed your Glock sights, you’ll want to make sure you reattach the parts that needed to be removed to replace your Glock sights. Most Glock models, from the 19 to the 43 and 43X, are known for their simple frames, so this step, hopefully, is not too time-consuming. Once your firearm is put back together, be sure to carefully inspect it to make sure everything is properly put back together and functioning well.

The Benefits of Professional Glock Sight Installation

If you’re wondering if there are other options for safely installing your Glock sights, you’re in luck. You could choose to have them installed by a professional gunsmith. Because gun owners have access to a wide range of sights to choose from, it can be confusing to simply follow an owner’s manual. That’s where we come in. Once you’ve purchased your sight, you can add on our sight installation service. This comes with a number of great benefits.

At Zaffiri Precision, we have the specific tools required for sight installation, including sight pushers that can make installation easier and more precise.

Safety

While the process of changing sights isn’t inherently dangerous, working with firearms always involves some level of risk. A professional will know how to manage this risk and ensure that the installation is done safely and efficiently.

Damage Prevention

We’ve all been there at some point. While doing an in-home repair or replacement to one of our firearms, something goes wrong. It sucks. Incorrect installation can potentially damage the new sights or the gun itself. So, turning to a professional gunsmith can reduce the risk of this.
