The Glock 19 in 9mm Luger is the most popular pistol with civilians worldwide, and for more reasons than one. It’s compact, lightweight, reliable, and very easy to customize. One of the best customizations that you can make to your Glock 19 will be to invest in a threaded barrel, especially if you plan on using a suppressor with your pistol.

In this guide, we’ll discuss the history and development of the Glock 19 and what led to it becoming so popular, the main reasons to consider adding a threaded barrel to it, the top qualities to look for in a threaded barrel, and then our choices for the top three best threaded barrels on the marketplace today.

History and Development of the Glock 19

The Glock 19 holds the distinction of being the highest selling and most popular centerfire semi-automatic pistol sold in the United States today. There’s good reason for that, and the fact that the Glock 19 is so popular means that there is virtually an unlimited number of spare parts and accessories available for the weapon.

The Glock 19 was first released in 1988 was the more compact version of the Glock 17, which had been first released in 1983. The Glock 17 completely revolutionized the firearms world because it was the first striker fired, polymer frame pistol that took the industry by storm. It was quickly adopted as the standard issue sidearm by the Austrian military, and in a matter of years, the Glock became the most widespread pistol in use with militaries and law enforcement units all over the globe.

There’s simply no question that the Glock has been the single most influential pistol since its release, as virtually every other handgun maker now makes their own version of the Glock-like, striker fired single action auto. The CZ P10C, Smith & Wesson M&P, Springfield XD, HK VP9, and the Walther PPQ (among others) are all direct competitors to the Glock and adopt several of the same internal design features.

A solid argument can be made, however, that the Glock 19 (rather than the larger and heavier Glock 17) is the one pistol to have if you could only have one. It’s a compact pistol that is small enough to adequately conceal carry and yet large enough to fight with as a duty weapon.

The 9mm Luger that the Glock 19 is chambered for is also the most widespread and affordable pistol caliber cartridge in the entire world. Self-defense loads for the 9mm today are also much more effective than they used to be, and recoil is moderate and easily controllable.

The Glock 19 also holds 15+1 rounds in the standard capacity, which is impressive firepower for any handgun (let alone a compact model). However, it will also accept the longer Glock 9mm 17 round and even 33 round magazines as well (even though they will protrude beneath the grip). A Glock 19 with a 33 round magazine in particular would make for a formidable and effective home defense weapon to keep resting on your nightstand.

The Glock in general also more spare parts and accessories available for it than any other handgun you can get. In fact, the only other firearms that come anywhere close to the Glock in total customization options are the 1911 series of pistols, the AR-15 series of rifles, and the Ruger 10/22 .22 carbine.

Furthermore, the Glock has an excellent reputation for reliability and durability. It’s also incredibly simple to operate and has few controls, which helps give it a more minimal profile and makes it easier to learn how to use.

In total, for these reasons a solid argument can be made that the Glock 19 is the most practical pistol in history: its reliable and durable; it can be used for home defense, concealed carry, and tactical scenarios; it’s easily customizable; it fires common ammunition and offers impressive firepower; and its incredibly simple to operate.

The Glock 19 as it comes from the factory is already an excellent pistol, but it can be improved further. If you plan on installing a suppressor on your Glock 19 to use for certain scenarios, for instance, then something you’ll need to invest in is a threaded barrel.

We’ll discuss what a threaded barrel is and the reasons to own one in the next section.

Why Add A Threaded Barrel To Your Glock 19?

Why should you add a threaded barrel to your Glock 19? There are many pros and cons to doing so.

But first, we need to answer this question: what even is a threaded barrel in the first place?

In this context, a threaded barrel refers to a slightly extended barrel that protrudes slightly out from the muzzle of the slide. It comes with threads on the end to install suppressors, muzzle brakes, and other muzzle devices.

Most people who buy a threaded barrel for their Glock 19 do so to add a suppressor to it. Plain and simple, you cannot affix a suppressor or a silencer to your Glock without the aid of a threaded barrel.

This then naturally begs the question: why should you add a suppressor? There are two very practical reasons for owning a suppressor that go beyond it looking or sounding cool. The first reason is to minimize noise in a home defense situation. Shooting a gun indoors will be extremely loud and disorienting to your ears, and while a suppressor will not silence the noise completely it will mitigate it substantially.

The other reason to own a suppressor for your Glock is for shooting at the range when you want to create less noise as well. For example, if you live out in the rural regions of the country where you can shoot on your property but are still in relatively close proximity to your neighbor, a suppressor will be a nice accessory to have so you do not disturb your neighbors.

As you can see, there are fully practical reasons to owning a suppressor, contrary to what some people may tell you. Yes, a suppressor will add weight and length to your pistol, but the above pros still ring true. And again, a threaded barrel will be necessary to affix a suppressor to your Glock.

There are cons to going with a threaded barrel to. As noted, the threads of the barrel are going to protrude out slightly from the muzzle of the slide. This adds length to your Glock, and while it’s minimal it’s still worth noting.

Furthermore, there’s really no reason to buy a threaded barrel for your Glock if you’re not going to also buy a suppressor for it. So ultimately, if you’re not planning on adding a suppressor or any other kind of muzzle device that needs threads, buying a threaded barrel won’t be necessary for you.

The good news is that adding a threaded barrel to your Glock is incredibly easy. All you have to do is field strip the weapon, remove the old barrel you have in it currently, and then place in the new threaded barrel. Reassemble the weapon as you always do, and you’re all set.

This means if you don’t like the look of the threaded barrel and are not using a suppressor, you’re not stuck with it. You can quickly install the threaded barrel to affix a suppressor when needed in as little as thirty seconds.

Take note that when you buy a threaded barrel for your Glock 19, you must make sure that it is for the Glock 19. A barrel designed for a Glock 26, 17, 34, or any other Glock 9mm is not going to work for a G19 model. If a threaded barrel is sold as “Glock 9mm”, there should be fine print indicating which specific model of 9mm Glock that it is for.

Buyer’s Guide For The Best Glock 19 Threaded Barrels

These are the most important factors to consider when looking for a new threaded barrel for your Glock 19:

Durability

First and foremost, you want your threaded barrel to be as durable, as well as rust and corrosion resistant as possible. The best threaded barrels will be built out of 416R stainless steel with a black nitride finish for excellent rust and corrosion resistance as well. Carbon steel is also a durable option, and while not quite as strong or rust resistant as stainless steel, it’s also usually more affordable for when you’re on a budget.

Compatibility

Not all Glock threaded barrels are designed to work with all Glocks. Most will, but some will be designed only for specific generations of the Glock. For example, some threaded barrels may be compatible with Generation 3, Generation 4, and Generation 5 guns but not with earlier models.

Beyond being compatible with your generation of Glock, you also need to make sure that your barrel will be compatible with whatever accessories you plan on adding onto it. For example, if you plan on adding a suppressor or muzzle brake to your Glock, make sure that your threaded barrel is compatible with the suppressor or brake that you will be using.

Accuracy

At the bare minimum, your new threaded barrel should be equally as accurate as the factory barrel that comes installed on your Glock, if not more so.

The 3 Best Glock 19 Threaded Barrels For 2021

Now that we’ve covered why you need to upgrade your Glock 19 with a new threaded barrel and the top qualities to look for in one, here are our choices for the top three best Glock 19 threaded barrels for this year:

Silencerco Glock 19 Threaded Barrel

Silencerco Glock 19 Threaded Barrel

The Silencerco Glock 19 Threaded Barrel is one of the very best threaded barrels that is available for the Glock 19. It’s built out of a very durable and rust resistant 416r stainless steel. For even added corrosion resistance, it comes with a black nitride finish over the top. However, if you would prefer the traditional silver stainless look, there is an option for you to purchase the Silencerco without the nitride. The black nitride finish, however, would match better with the factory black finish on the Glock 19.

The Silencerco has 1/2×28 threads per square inch, which means that it is only compatible with the generation 3 and generation 4 Glock 19s. If you own an earlier generation Glock, you’ll need to keep searching. Fortunately, the Silencerco does come with a thread protector, which is a welcome feature especially when you consider that several threaded barrels do not come with one.

Accuracy out of the Silencerco is also excellent, and many users report shooting tighter groups out of the Silencerco than with the factory Glock 19 barrel.

The 1/“ 28 threads are compatible with most Glock muzzle brakes, sound suppressors, and compensator. The Faxon also comes with an 11” recessed target crowned muzzle.
