Why threaded barrels?

Regardless of whether you plan to purchase a suppressor, threaded barrels are an excellent upgrade to any tactical handgun. Additionally, threaded barrels allow you to attach breaching muzzles, which increases the muzzle velocity of your bullets and adds a major “cool factor” to your handgun.

Do I need to Buy a Suppressor?

Buying a threaded barrel doesn’t mean you have to immediately purchase a suppressor. However, most gun owners who bought threaded barrels for their Glock 19 do so to attach a suppressor with it. Unfortunately, you can’t attach a suppressor to a Glock 19 out of the box. So aftermarket threaded barrels are the only option.

It’s a common misconception that suppressors are reserved for special forces or tactical applications. But in reality, the most compelling reason to get a suppressor for your handgun is to lessen the amount of noise it makes when firing.

Although suppressors cannot completely erase the sound of a gunshot, they significantly reduce it. When it comes to self-defense at home or any other type of indoor shooting, this is a huge advantage.

Downsides of Threaded Barrels

Threaded barrels have a few limitations, but overall they’re still useful. However, a threaded barrel will increase the overall length of your weapon. Because of this, your Glock 19 won’t be compatible with as many holsters as it would otherwise be. If you have holsters with closed bottoms, automatically assume they will no longer fit with a threaded barrel Glock 19.

The good news is, thanks to the Glock system, threaded barrels have become a simple drop-in installation. This means you can switch out a regular barrel with a threaded barrel in as little as 30 seconds. Also, if you don’t really plan to use a suppressor or any other kind of muzzle device with your Glock 19, then maybe you don’t really need to buy a threaded barrel after all.

Buyer’s Guide to the Best Glock 19 Threaded Barrel

Before heading out to a gun shop or adding some items to your cart online, take a quick read of the most important factors to consider when looking for a new Glock 19 threaded barrel.

Durability

If you want your handgun to serve you well for many years, you need to invest in a well-made threaded barrel. The best Glock 19 threaded barrels have a 416R stainless steel build covered with a corrosion-resistant coating like nitride for optimum performance. However, if you’re working on a tighter budget, then getting a carbon steel Glock 19 barrel will save you a lot of money.

Compatibility

This is probably the most important thing to consider with Glock 19 parts in general. Not all Glock 19 threaded barrels are designed to work with all generations of the Glock 19. Most threaded barrels are interchangeable between Glock generations. However, you’ll inevitably run into some that aren’t. For example, some barrels might be compatible with Glock 19 Gen 3 and 4 except for the Generation 5 models.

In addition to being compatible with your specific Glock generation, your barrel should also be compatible with any additional attachments you want to add to it. Be sure your threaded barrel is compatible with your intended suppressor or muzzle brake if you’re thinking about installing one to your Glock.
