Why Would You Want an Aftermarket Barrel?

The Glock is known for being an accurate and reliable pistol right out of the box. So, why would you want to replace the stock barrel with an aftermarket barrel?

The most common reason people replace their stock barrel with an aftermarket one is for increased accuracy. A well-made aftermarket barrel can provide tighter tolerances and a better fit than a factory barrel. This can lead to more consistent shot placement and improved accuracy.

Another reason people opt for an aftermarket barrel is for the looks. Some people simply don’t like the way their stock barrel looks and want to change it up. There are also a number of coating options available for aftermarket barrels that can give your gun a unique look.

How Do You Choose an Aftermarket Barrel?

There are a few things you’ll want to keep in mind when choosing an aftermarket barrel for your Glock.


First and foremost, you’ll want to make sure the barrel you’re considering is compatible with your Glock. There are a number of different Glock models and each model has its own specific barrel threading. Most aftermarket barrels will list the models they’re compatible with on the product page.


One of the most important things to consider when choosing an aftermarket barrel is the material it is made from. The most common materials used for gun barrels are steel, aluminum, and polymer. Steel is the most durable option and will typically last the longest, but it is also the heaviest. Aluminum is a lighter-weight option that is also durable, but it may not last as long as steel. Polymer barrels are typically the lightest weight option, but they may not be as durable as the other two options.

Type of Rifling

The type of rifling on a gun barrel has a big impact on accuracy. The most common types of rifling are button rifled,polygon and broach cut. Button rifled barrels are made by pushing a button through the barrel from the chamber end. This leaves behind spiral grooves that give the bullet spin. Polygon barrels are made by machining spiral grooves into the barrel. Broach cut barrels are made by using a tool to cut spiral grooves into the barrel. Each of these types of rifling has its own advantages and disadvantages.


Aftermarket barrels can range in price from $100 to $500. The most expensive barrels are typically made from high-quality materials and offer the best accuracy. However, there are also a number of more affordable options that can still provide good accuracy. It’s important to find a balance between quality and price that fits your needs.


Another thing to consider when choosing an aftermarket barrel is the length. The length of the barrel will affect both the accuracy and the velocity of the bullet. Generally speaking, a longer barrel will be more accurate than a shorter barrel, but a shorter barrel will have a higher velocity. Therefore, it is important to choose a length that is appropriate for the type of shooting you will be doing.

Twist Rate

The twist rate of a barrel is the number of inches that the bullet will travel in one complete revolution around the barrel. The twist rate affects both accuracy and velocity. A higher twist rate will typically result in more accuracy, but a lower twist rate will typically result in a higher velocity. Therefore, it is important to choose a twist rate that is appropriate for the type of shooting you will be doing


Another thing to consider when choosing an aftermarket barrel is the profile. The three most common profiles are button-rifled, hammer forged, and cut-rifled. Button-rifled barrels are the most accurate, but they are also the most expensive. Hammer-forged barrels are less accurate but are much cheaper. Cut-rifled barrels are in between in terms of accuracy and price.


Another factor to consider when choosing an aftermarket barrel is the coating. The most common coatings are black oxide, nitride, and chrome. Black oxide is the cheapest and least durable option. Nitride is more expensive but is more durable and provides better corrosion resistance. Chrome is the most expensive but is the most durable and provides the best corrosion resistance.


Another thing to consider is what features you want in an aftermarket barrel. Some barrels come with additional features like ported muzzle and threading for attaching a suppressor. Decide which features are important to you and look for barrels that offer them.


Lastly, you’ll want to decide what finish you want on your barrel. The most common options are black nitride and chrome. Black nitride is more durable but can be more difficult to clean than chrome. Chrome is easier to clean but doesn’t have the same level of durability as black nitride.
