The Best Threaded Glock Barrels for Adding a Glock Muzzle Device

Last Updated on

So, you’ve got your Glock 19. And it’s pretty sweet, even in its bone stock configuration.

However, there are a few things that aren’t included in the stock Glock package. A threaded barrel is one of those things. Yes, Glock does make Glock 19 OEM Threaded Barrels, which are pretty good.

But they aren’t the only option. And if you want something a little less plain, you’ll need to head out into the wide world of Glock aftermarket parts. There you’ll find roughly a bazillion Glock 19 barrels.

Allow us to help you sort through the list.

1. SilencerCo Threaded Barrels - Overall Best Threaded Glock 19 Barrel

SilencerCo Threaded Barrels are some of the best Glock 19 threaded barrels you can get, full stop. But they’re also very reasonably priced.

The main benefit of this barrel is that it’s a stainless steel barrel. Stainless steel tends to be a tad more precise than some of the other barrel steels. That’s because stainless steel wears more evenly than other steels, which means there’s very little point of impact shift throughout the life of the barrel.

This barrel comes in either a raw stainless steel finish or black nitride coated to protect your barrel from corrosion.

Lastly, this barrel is button rifled, which offers a tad more precision than the OEM barrel. And you can shoot lead bullets out of this barrel without excessively fouling the rifling. So it expands your ammo compatibility.

However, traditional rifling produces slightly lower muzzle velocities than polygonal rifling. Most shooters won’t notice the drop in muzzle velocity, though.

If you want an excellent threaded barrel that’s compatible with most suppressors and offers a slight precision upgrade for your Glock 19, this barrel is a perfect choice.

Pros

  • Steel is durable and precise throughout its lifespan.
  • Button rifling offers slightly better precision than the Gen 3 and 4 OEM barrels.
  • Can handle lead bullets without excessive fouling.
  • 1/2x28 threads are compatible with most suppressors.

Cons

  • Traditional rifling produces slightly lower muzzle velocities than the OEM polygonal rifling.

2. Radical Firearms Glock Threaded Barrel - Budget Threaded Glock 19 Barrel

I was pretty skeptical of the Radical Firearms Glock Threaded Barrel because the price seems too good to be true. However, this is actually a decent barrel. Though, you do get what you pay for.

First, this is a stainless steel barrel. It’s black nitride coated to keep the rust away. And it’s got the standard Glock barrel hood shape. It’s well-built, and it won’t change the look of your Glock 19, just in case you’re into the blocky aesthetic.

And, like most aftermarket barrels, this barrel uses traditional rifling to enhance your precision.

However, the finish is where this barrel shows its price point. The black nitride wears off pretty quickly in areas where the slide rubs the barrel.

Also, shooters who run a lot of rounds through their handguns say that this barrel has a slightly shorter lifespan than more expensive barrels. Though, that’s still thousands of rounds.

So, unless you shoot A LOT, this Radical Firearms barrel is a solid option for attaching a suppressor to your Glock 19 without ripping out your wallet’s guts.

Pros

  • Super affordable.
  • Stainless steel construction with a black nitride finish is durable and looks great.
  • Traditional rifling increases organic precision and shoots lead bullets without excessive fouling.
  • Looks just like an OEM barrel to keep your Glock looking like a block.

Cons

  • Slightly shorter lifespan than some higher priced barrels, but still lasts for thousands of rounds.
  • Starts to show slide wear fairly quickly.
  • Slightly lower muzzle velocities than a polygonal rifled barrel.

The TRYBE Defense Glock 19 Match Grade Threaded Pistol Barrel is a very affordable match-grade Glock 19 barrel. However, most of the quality is on the inside of this barrel (which is where it matters, to be fair).

This barrel is stainless steel with traditional rifling. This increases the organic precision of a Gen 3 or Gen 4 Glock 19. And this barrel will hold its point of impact until it needs to be replaced.

The traditional rifling also runs cleaner with lead bullets.

I found that the finish on this barrel looks great. And the TRYBE Defense logo on the barrel hood is pretty cool.

However, the black nitride finish seems to wear through pretty quickly. You’ll start to see wear from the slide in less than 1000 rounds. The titanium finishes seem to hold up much better, though.

But it’s pretty normal to get wear on the barrel where the slide makes contact. Eventually, even the OEM barrel starts to show this sort of wear.

Overall, though, this TRYBE Defense barrel is still a great buy for the money that adds some nice aesthetic touches to your Glock 19 and performs well.

Pros

  • Stainless steel and traditional rifling enhance organic precision, which stays true throughout the life of the barrel.
  • Runs cleaner with lead bullets than a polygonal rifled barrel.
  • Finish and TRYBE Defense logo look great.

Cons

  • Nitride finish wears through very quickly where the slide contacts the barrel.
  • Traditional rifling adds precision but sacrifices a small amount of muzzle velocity compared to polygonal rifling.

4. Faxon Firearms G19 Threaded Barrel - Best Threaded Glock 19 Barrel for the Money

I’m a pretty shameless shill for Faxon Firearms barrels. I’ve used them in both rifle caliber and pistol caliber carbines. The fit and finish is great. And the performance is excellent. So naturally I think the Faxon Firearms G19 Threaded Barrel is a great choice.

This barrel comes in either 416-R or 4150 steel. Either one is an excellent choice for a pistol barrel and will last for thousands of rounds without a noticeable shift in point of impact.

However, the rifling and crown on this barrel makes it at least as precise as the Glock Marksman Barrel (maybe more precise…). It’s got the same button rifling and target crown. These characteristics enhance the organic precision and run cleaner with lead bullets.

Additionally, the salt bath nitride finish is incredibly durable. And it looks awesome. Yes, eventually you’ll get some slide wear on your barrel. And the finish might not hold up quite as well as the Glock OEM finish, because that finish is ridiculous.

But the finish on this barrel holds up through a remarkably high round count.

Also, the machining on the barrel hood makes this Faxon Firearms barrel look cool. But it’s not overdone. It’s still clean and professional.

I prefer the plain barrel because the flame fluting is a bit too aggressive for my taste. But the flame fluted model is a good option if you want improved cooling and a very unique aesthetic.

This isn’t the cheapest barrel you can get. But it’s also not the most expensive. And the performance and durability are excellent.

Pros

  • Manufactured from stainless steel to hold the same point of impact throughout the life of the barrel.
  • Button rifling and target crown enhance the organic precision.
  • Shoots cleaner with lead bullets than a Gen 3 or Gen 4 OEM barrel.
  • Finish and barrel hood machining look great.
  • Flame fluting improves cooling and adds a very unique aesthetic.

Cons

  • Flame fluting might be too aggressive for some shooter’s taste (but there’s a plain model available).
  • Finish is really durable, but not quite as durable as the Glock OEM finish.
  • Slightly lower muzzle velocities than polygonal rifled barrels.

5. Lone Wolf AlphaWolf 9mm Threaded Barrel - Fluted Threaded Glock 19 Barrel

The Lone Wolf AlphaWolf 9mm Threaded Barrel has been a staple in the threaded barrel market for a long time. This might have been the first fluted Glock 19 barrel I ever shot with.

The thing about this barrel is that it’s made of 416 steel, rather than 416-R steel. So it’s slightly harder than most aftermarket barrels. This gives it an exceptionally long lifespan. And the point of impact stays the same throughout the service life.

Additionally, the salt bath nitride finish on this barrel is remarkably durable. It also has a semi-matte finish that looks really good with the finish on the Glock slide. And it resists slide wear almost as long as the Glock OEM finish.

The big deal with this barrel is that it’s fluted, though. The fluting makes the barrel more rigid. And it improves cooling. Ultimately, it makes your Glock a bit more heat resistant, which is nice if you do a lot of rapid fire.

However, I appreciate that this Lone Wolf barrel has a standard Glock barrel hood. The fluting doesn’t really affect the aesthetic of your gun as long as the slide is forward. It’s a good barrel for those who like the stock aesthetic, like I do.

So, if you’re looking for a fluted barrel that’s also incredibly durable and well-made, this is the Glock 19 threaded barrel for you.

Pros

  • 416 steel offers an exceptionally long lifespan.
  • Remarkably durable salt bath nitride finish lasts for a long time before it starts to show slide wear.
  • Fluting makes barrel more rigid and improves cooling.
  • Retains most of the standard Glock aesthetic.
  • Traditional rifling enhances precision and works better with lead bullets.

Cons

  • Standard rifling produces slightly lower muzzle velocities than polygonal rifling.

6. Stormlake Pistol Barrel for Glock 19 - Stainless Steel Threaded Glock 19 Barrel

The Stormlake Pistol Barrel for Glock 19 used to be THE BARREL TO GET if you wanted a stainless steel Glock 19 barrel. There are a lot more competitors than there used to be. But this is still an excellent threaded Glock 19 barrel.

Obviously, it’s stainless steel. So this barrel wears evenly and maintains its point of impact for as long as it lives.

It’s also cut with traditional rifling to improve the organic precision of your handgun and reduce fouling with lead bullets. Normal stuff, so far.

However, this barrel has (very) slightly tighter slide fit tolerances than an OEM barrel. Your Glock will still be just as reliable as it was with an OEM barrel. But, the improved barrel fit further improves the organic precision of your handgun.

This barrel is only offered in the raw stainless steel finish. That’s good and bad.

It’s good if you like the stainless steel look. And this barrel doesn’t show slide wear very much, since it’s already silver.

It’s not great if you prefer a black barrel. Also, the plain finish makes this barrel slightly more susceptible to rust.

That’s a small gripe, though. In the end, this Stormlake model is one of the few barrels that actually goes beyond the rifling to improve the organic precision of your Glock 19.

Pros

  • Stainless steel construction improves organic precision and retains its point of impact throughout the life of the barrel.
  • Traditional rifling enhances precision and runs cleaner with lead bullets than polygonal rifling.
  • Very slightly tighter tolerances further enhance organic precision.
  • Raw stainless steel finish doesn’t show slide wear very much.

Cons

  • Only available in raw stainless steel finish.
  • Traditional rifling offers slightly lower muzzle velocities than polygonal rifling.

7. CMC Triggers Match Precision Fluted Barrel - Match Grade Threaded Glock 19 Barrel

CMC Triggers makes exceptionally high quality components. And the CMC Triggers Match Precision Fluted Barrel is a superbly made barrel for those who want match grade performance and suppressor compatibility.

This barrel is made of 416-R steel, which is standard for pistol barrels. It wears evenly and retains its point of impact until it wears out.

However, the precision enhancing aspects of this barrel are what really stand out.

First, it’s machined to slightly tighter tolerances for a more secure slide fit and lock up. That means better organic precision.

However, this is one of the few barrels that uses hexagonal rifling to maintain the OEM muzzle velocity. But his barrel uses 6-groove rifling to for added precision without as much drop in muzzle velocity.

It’s not quite as precise as a traditionally rifled barrel. But it’s still a tad more precise than a Gen 3 or Gen 4 OEM barrel.

Unfortunately, the hexagonal rifling doesn’t run as clean with lead bullets as a traditionally rifled barrel. Most shooters won’t notice, though, unless they never clean their gun.

Lastly, this CMC Triggers barrel also has fluting to make the barrel more rigid and improve cooling.

In the end, this barrel is a bit pricey. But the performance features and build quality are outstanding. It’s probably the best barrel for those who want suppressor compatibility with match-grade performance.

Pros

  • Stainless steel construction is durable and wears evenly to preserve the point of impact throughout the life of the barrel.
  • Machined for a tighter slight fit and more secure lockup for improved precision without compromising reliability.
  • Hexagonal rifling improves precision while retaining the muzzle velocity of an OEM barrel.
  • Fluted to improve rigidity and cooling.

Cons

  • Runs a bit dirty with cast lead bullets.
  • Hexagonal rifling doesn’t produce quite as much precision as traditional rifling, though still very good.

Tightening Down

Threaded barrels are handy for attaching more than just suppressors. You also need a threaded barrel for a compensator.

And a threaded barrel adds a half inch or so to the overall length of your Glock 19 barrel. Is the performance difference between a standard barrel and a threaded barrel negligible? Probably. But every little bit counts, right?

SilencerCo Threaded Barrels

If you still haven’t made a decision, get one of the SilencerCo Threaded Barrels. They’re awesome barrels that are made by a company that knows about attaching muzzle devices to guns.

There are a lot of options. But now you know which ones are best. So it’s time to make your Glock 19 muzzle device compatible.
