How to Choose the Perfect Glock 19 Barrel for Your Shooting Needs

When it comes to choosing the perfect Glock 19 barrel for your shooting needs, there are a few important factors to consider. Knowing what to look for in a Glock 19 barrel can help you make an informed decision and get the most out of your firearm. In this blog post, we will go over what you need to know about choosing the right Glock 19 barrel for your shooting needs.

1) Stock vs. Aftermarket

When it comes to choosing a Glock 19 barrel, you have two main options: stock or aftermarket. Stock barrels come factory installed with your Glock 19 and are designed specifically for it. Aftermarket barrels, on the other hand, can be purchased from online retailers like and allow for more customization.

Stock barrels are reliable and are a good choice for casual shooting and everyday carry. They are typically made of stainless steel and feature traditional land and groove rifling, also known as button rifling. This type of rifling is relatively accurate and relatively inexpensive to produce, making it a good choice for stock barrels.

Aftermarket barrels offer greater customization potential for the Glock 19 enthusiast. Many aftermarket barrels are made of 416R stainless steel and feature polygonal rifling, which offers higher velocity and better accuracy than traditional land and groove rifling. These barrels may also feature nitriding or fluting, which further enhances their performance and durability. If you’re looking to get the most out of your Glock 19, an aftermarket barrel is definitely worth considering.

2) Polygonal Rifling

When it comes to Glock 19 barrels, you may have heard the term “polygonal rifling” thrown around. Polygonal rifling is a specialized form of barrel rifling which is characterized by having a polygonal shaped bore. It has a slightly different shape than the traditional rifling, and this affects the way the bullet spins and travels down the barrel.

Polygonal rifling can be found on both stock and aftermarket Glock 19 barrels from Polygonal rifling generally has fewer grooves, and the sides are more curved than traditional rifling. This type of rifling also requires less cleaning and maintenance due to the smoother surface, so it is becoming increasingly popular for handgun owners. Additionally, it reduces wear and tear on the Glock 19 barrel, allowing it to last longer. Finally, it also reduces contact between the projectile and the barrel walls, resulting in improved accuracy, less fouling, and an overall better shooting experience.

3) Button Rifling

Button rifling is a type of rifling process used for the production of gun barrels. This method uses a button-shaped tool which is forced into the bore in order to form the rifling grooves. With this method, the individual grooves are formed independently and do not require an additional cutting process. The advantage of button rifling is that it produces very consistent and accurate barrels.

For a Glock 19 barrel, button rifling is often seen as a more precise way of producing consistent and accurate firearms. Many customers opt for aftermarket barrels with button rifling to ensure the accuracy of their pistols. If you are looking for an accurate and consistent barrel for your Glock 19, considering one with button rifling may be a good option.

4) Nitriding

Nitriding is a popular process used to treat the steel of a Glock 19 barrel. It’s a type of thermal heat treatment that increases the hardness and corrosion resistance of the barrel without affecting its dimensional accuracy. The process involves introducing nitrogen into the steel, forming a compound with the iron atoms to make it harder. This makes the steel less prone to wear and tear from regular use and environmental factors. The surface layer of nitride Glock 19 barrels also has improved lubricity, which can reduce friction between the barrel and ammunition for improved accuracy.

5) Fluting

Fluting a Glock 19 barrel can add some performance benefits to your gun. Fluting is a machining process that creates grooves in the barrel. These grooves reduce the weight of the barrel, improve the rigidity and strength, and allow for better heat dissipation. Fluted barrels also provide an aesthetic enhancement, adding visual appeal to the gun.

When choosing a fluted Glock 19 barrel, there are two main types to consider – straight or spiral fluting. Straight fluting is usually more uniform and consistent than spiral fluting, while spiral fluting offers a more visually appealing look. It’s important to note that while fluting reduces the weight of the barrel, it also affects its ability to dissipate heat and therefore could lead to increased wear on the gun over time.

If you’re looking to upgrade your Glock 19 barrel with fluting, it’s important to do your research and make sure you get the right fit and style for your gun.
