Factors to Consider When Looking at the Best Aftermarket Glock Barrels

Caliber

As Glock owners will know, the handgun is actually available in a wide range of calibers. This essentially means you’ll need to go for replacement barrels that will match your Glock handgun’s caliber. While this may appear to be stating the obvious, it’s extremely important to understand that through a simple barrel and magazine swap, some Glock models actually can be converted to chamber different calibers.

Glock specifically designed some of their pistol models to allow this so shooters can take full advantage of the less expensive ammunition and benefit from lighter recoil. When it comes to swapping out your Glock barrel, you must always make sure that the type of caliber is the one you intend to use.

Barrel length; Threaded or Non-threaded?

Aftermarket Glock barrels often come in a wide range of lengths. You should always look for a replacement barrel that matches the original factory length. If you don’t plan to attach a suppressor, compensator, or any muzzle device on your Glock, getting an unthreaded Glock barrel will be fine and plus, they are cheaper too.

That said, if you do intend to attach a suppressor or a compensator on your replacement barrel, you might want to consider investing in a threaded glock barrel. While you might be paying a little more for the barrel, you’ll definitely save more money in the long run. This is because if one day you discover that you’d want a non threaded barrel, a complete replacement will be required and you must be prepared to fork out at least $100 for this.

Finish Options

This really depends on what style and aesthetics suit you better. While the factory glock barrels are solid, they come in a ‘Tenifer’ finish. This is largely due to their durability, robustness, and corrosion resistant finish. There’s no doubt that these factory glock barrels are solid and reliable as hell, but they sure aren’t pretty.

There are plenty of aftermarket glock barrels that are more solid, reliable and pretty at the same time! You may opt for aftermarket glock barrels that come with a Titanium Nitride, Stainless Steel, or a Cerakote finish. Cerakote finishes will come in just about every color you can imagine and many shooters actually fancy it in an aftermarket glock barrel.

If you didn’t know, Lone Wolf has been working very hard to be where they are today – the leader of Glock aftermarket barrels. When it comes to manufacturing Glock aftermarket barrels, Lone Wolf doesn’t simply produce your everyday Glock OEM replica, they take a few steps forward by constructing a wide range of unique Glock aftermarket barrels.

If you are looking for an aftermarket barrel to significantly increase your shooting accuracy, you will love the Lone Wolf Alpha Wolf range of barrels. This line of aftermarket Glock barrels should be the benchmark when it comes to achieving excellent accuracy and reliability from your Glock handgun.

These aftermarket glock barrels were specifically designed to take lead plated or jacketed ammunition. Lone Wolf decided to ditch the hex rifling for traditional rifling. Hence, the benefit of this is that you’ll be able to shoot lead ammo on this Lone Wolf barrel without ever having to worry about dangerous buildup of deposits which Glock constantly warns against with their factory barrels.

In terms of barrel length, they have plenty for you to choose from. When it comes to longevity and reliability, you won’t have any issues with the Lone Wolf Alpha Wolf range of barrels as these aftermarket Glock barrels were treated to RC 40-42 standards and coated in a Nitride salt bath. As such, you know the Lone Wolf Alpha Wolf match barrels are going to last you for quite sometime even if you often shoot under unfavourable weather conditions.

One of the biggest differences between the usual Glock OEM barrels and the Alpha Wolf aftermarket Glock barrel lies in the barrel threading design. This threading design is something you won’t find in Glock’s factory barrels/stock barrels. Besides having great shooting accuracy on your Glock handgun models, mounting suppressors and other muzzle devices are also extremely easy.

You are planning on mounting a suppressor. One of the biggest and best differences between an Alpha Wolf and a Glock OEM and/or factory barrel is the option of barrel threading. This is something that Glock simply doesn’t do. If you are planning to mount a suppressor on your Glock models, not having a threaded barrel can turn a simple attachment into the world’s biggest headache.

You plan to convert your Glock’s caliber. The coolest thing about Lone Wolf’s barrels is perhaps the conversion kits. If you didn’t know, Lone Wolf actually has a number of different barrels that convert various Glock models from one caliber to another. As such, you can easily turn your Glock 35 into a .357, your Glock 29 into a .40 S&W, and so on.

You might not like this product if:

You are an amateur shooter. Unless you are shooting in a 3Gun competition or anything of this sort, you probably won’t notice a significant difference between your OEM barrel and this Alpha Wolf variant. That said, you’ll still enjoy the Lone Wolf’s conversion kits, threaded feature, and the fact that it allows you to safely fire lead plated or jacketed ammunition.

Introducing the ZEV Technologies PRO Threaded Barrel. Not only is this aftermarket barrel super stylish when fitted, it will also deliver excellent accuracy.

This shows that not only is this aftermarket block barrel resilient, it will also be able to withstand any excessive pressure from suppressed shooting.

Talking about suppressors, yes, as the name suggests, this is a threaded Glock barrel and it is the one you’re looking for. Unlike the some other aftermarket Glock barrels, mounting a suppressor on a Glock has never been made easier with the ZEV Technologies PRO.

Another great thing about this barrel is its increased versatility. While the Glock OEM replicas/barrels are almost perfect in every way, they will restrict you to only FMJ (full metal jacketed) rounds. With the ZEV Technologies PRO Threaded Barrel, you can opt to shoot less expensive lead rounds safely and accurately as they don’t come with the traditional polygonal rifling.

You will like this product if:

You want an aftermarket barrel that’s built to last.

If you have a tight budget, this might be beyond your budget. That said, if you are willing to invest a little more in getting better returns in the long run, you can’t go wrong with a ZEV Glock barrel.

Besides looking great, the lightning cuts from the V1 and ‘Geo Scales’ from the V2 also comes with practical features such as reducing muzzle weight and providing a better grip.

You plan to mount Trijicon’s RMR sights. One of the most outstanding features about this barrel and slide combo is that you can opt to order them already cut for Trijicon’s RMR. While it has a very tight tolerance, you know it’s not going anywhere once you tapped it in.

If you didn’t know, Glock OEM barrels incorporate something called ‘polygonal rifling’. While this sort of rifling will allow you to achieve the best muzzle velocity for your ammunition, they aren’t as precise as land and groove rifling. Furthermore, if you plan to shoot cast lead bullets, you’re not gonna like the conventional polygonal rifling.

If you share the same concerns for polygonal rifling barrels, you’ll love the Victory First Brownells Edition Glock Barrel as it uses traditional rifling to tighten the organic precision of your Glock pistol and provides you with enhanced performance even with cheap cast lead ammunition.

While you might get slightly lower muzzle velocities than your Glock OEM barrels, the difference is negligible and in return, you will be getting excellent terminal ballistics with defensive ammunition.

The Victory First Glock barrel is machined from 416R stainless steel and comes with a matte black nitride finish. Hence, you know that this barrel is just as durable, if not more durable than your usual OEM barrel, both inside and out.

Furthermore, the Victory First barrel is even crowned to protect the rifling so you can deliver more consistent shot groups. This is essentially the same as the Glock Gen 5 OEM barrel, but it’s a major improvement if you are upgrading from a Gen 4 barrel. While this barrel might not be super flashy, it’s one of the best Glock upgrades you can get that won’t disturb its standard aesthetics at a reasonable price tag.
