(Top 6) Best Aftermarket Glock Slides

Glock handguns (and the so-called "Glock clones") are some of the most popular firearms in the world. They are being used widely across the globe by civilians, law enforcement, and many others. And if you’re a fan of action movies, it’s almost impossible you haven’t seen a Glock pistol at least once in them.

Because of its popularity, there are lots of aftermarket Glock parts manufacturers (aftermarket refers to parts not originally made by the manufacturer, in this case, Glock).

And since you’re here right now, chances are you are looking for a new slide for your Glock pistol to upgrade its performance, recoil, or even add support for micro red dot sight for example.

However, among many different aftermarket manufacturers, you can get overwhelmed by the vast selection of products and may not know which one is best for you.

That’s why we’re writing this article - to help you choose the best Glock slide, and at the same time, we will provide you our top 5 picks if you’re not sure which ones are best.

Why Change Glock Slide?

There are many reasons why you could upgrade your Glock pistol.

For example, you may want to add support for mini red dot sights, made for pistols.

On the other hand, you may want a longer slide or you may find aftermarket slides more attractive than the original one. There are plenty of reasons and probably you know best why would you like a better slide.

Considering these factors above, let’s explore what you should look for when choosing a Glock slide.

Factors to Consider When Choosing Glock Slide


Before purchasing a slide for your Glock, get to know which Glock you have.

For example, these pistols come in various models denoted with numbers like Glock 17, Glock 19, or Glock 29. Another factor is generation: these pistols are marked as Gen 3, Gen 4, and Gen 5.

Once you know your handgun generation, you can proceed with searching for specific slides matching the model and generation you already own.

Many manufacturers selling slides provide compatibility information so don’t forget to check specifications before making a purchase.


The most commonly used materials for Glock slides are aluminum and steel.

As you can guess, steel slides are a bit heavier than aluminum, but they offer better recoil control.

If however, you prefer a lighter firearm, then go with aluminum slides. With a lighter firearm, you have better handling and balance.

Keep in mind that aluminum slides may not be durable as those made of steel, however, picking material depends on your personal preference.


When it comes to corrosion and wear resistance of your handgun, finishes, and coatings play important roles in their protection.

For example, stainless steel is popular not only because of its durability but also because it’s corrosion-resistant.

Here are a few examples of finishes known for their corrosion resistance:

  • Stainless steel - as mentioned, it has great corrosion resistance. Stainless steel contains chromium, which forms a passive layer on the surface, protecting it from rust and corrosion.
  • DLC (Diamon-Like Carbon) - hard and durable coating with excellent corrosion resistance. It’s a type of carbon coating that offers low friction and high hardness, making it resistant to wear and corrosion.
  • Cerakote - ceramic-based finish offering good corrosion resistance. It’s a durable coating that provides a protective barrier against moisture and other corrosive elements.
  • PVD (Physical Vapor Deposition) - PVD coatings, such as TiN (Titanium Nitride) and TiCN (Titanium Carbonitride), provide a hard, thin layer on the surface of the slide, offering corrosion resistance.
