Recently we wrote an article about the best Glock slides to give you suggestions on which ones you can buy, as well as a few suggestions on how to pick the ideal Glock slide next time.
Well, after covering a part of the Glock handgun, we decided to proceed in the same manner to explore these pistols more in detail. Hence, now we’re writing an article about the best Glock barrels.
We will do our best to help you choose the next barrel, why to change it, and, of course, at the end, give a few examples of barrels you can purchase at our website.
Let’s begin.
Why Change a Glock Barrel
As you know, Glock is one of the high-quality pistols on the market, which is one of the reasons why this handgun got so much attention and popularity: not only among people but in many different video games and TV shows.
However, it can sound a little bit weird to change an original manufacturer’s barrel but there are still reasons you can do that.
Also, sometimes aftermarket parts are better than the original ones.
Barrel length options
Glock barrels come in different sizes: standard, compact, and subcompact.
You can change the barrel length depending on the purpose of use. For concealed carry, you should go with shorter barrels. This is just an example, but you get the idea.
Caliber conversion
If you didn’t know so far, Glock is designed to allow you caliber conversion. This can be done easily by changing the barrel of your Glock.
For example, you can convert a Glock 17 chambered in 9mm to shoot .40 S&W or .357 SIG by replacing the barrel.
However, some older models aren’t suitable for caliber conversion, so make sure you check this one before purchasing a different caliber barrel.
Accessories support
If you’re one of those guys looking to add additional accessories to your gun, pay attention if the barrel you’re looking for is threaded.
Threaded barrels are made to support various muzzle devices like flash hiders or suppressors (which are increasingly popular). However, there are some things to pay attention to when buying a suppressor. Take a look at our detailed guide about suppressors.
Accuracy enhancement
As with any other physical thing in the world, Glock barrels are also subject to wear over time.
Over time, the rifling inside a barrel can wear down affecting the bullet stabilization and of course the accuracy itself.
Replacing old and used barrels can help you solve this issue.
About Barrel Finishes
Glock barrels come with different types of finishes. Most common finishes you can find:
- Standard: Standard finish for Glock barrels is matte black or dark grey. This finish is achieved through a process called Tenifer or Melonite treatment, which hardens the barrel's surface and provides corrosion resistance.
- Stainless steel: Some barrels come with this finish. You probably already know stainless steel is durable and resistant to corrosion and wear.
- Nitride or DLC coating: nitride and Diamond-Like Carbon (DLC) coatings are used in Glock barrels to improve durability and corrosion resistance.
- Titanium Nitride (TiN) coating: The TiN coating is a popular choice for aftermarket Glock barrels. It offers a distinctive gold-colored finish and provides increased surface hardness and lubricity.
- Copper or bronze: Some Glock barrels feature a copper or bronze finish, either through actual plating or through coatings like Cerakote.
- Threaded barrels: Threaded barrels have a special finish to accommodate muzzle devices such as suppressors or compensators. These barrels typically have threads at the muzzle end, allowing the attachment of various accessories.
