Frequently Asked Questions

What type of barrel does the Glock 19 have?

The Glock 19 uses a steel barrel that is slightly longer than 4 inches. All Glock barrels, including the Glock 19, have a unique polygonal rifling, which makes them very accurate. This is one of the reasons Glocks are the preferred pistols of many shooters.

Why upgrade your Glock 19 barrel?

If Glock barrels are so reliable and accurate, then why should you upgrade them? It is a very reasonable question. Well, the polygonal rifling inside Glock 19 barrels does increase accuracy, but it can have a slight drawback as well. Glock barrels aren't designed to fire cast lead bullets. The lead can deposit inside the deep rifling grooves and make the pistol dangerous to operate over time. This is one of the reasons why some people choose aftermarket barrels that don't have polygonal rifling. More commonly, people go for thread, fluted, and match-grade barrels.

Aftermarket barrels can also offer shooters a way to improve the aesthetics of their pistols by choosing unique finishes.

What is a Glock 19 threaded barrel?

Factory Glock barrels, especially those on civilian models, aren't threaded. This means that you can't install a compensator, suppressor, or any other muzzle device on them. This is perhaps the most common reason people upgrade their Glock 19 barrels. Most aftermarket Glock 19 threaded barrels have 1/2 -28 threading, which is the most common standard for 9 mm firearms.

What is a fluted barrel?

Some shooters who want a lightweight pistol may also opt for a fluted barrel. These barrels have grooves of material removed from the barrel's exterior in a way that doesn't significantly decrease the barrel's strength but makes it lighter. Fluted barrels also have a larger internal surface area, which is better for heat dissipation.

What are “match-grade” competition barrels?

All Glock pistols use the Glock Marksman Barrels, which are inherently very accurate. They are perfect for personal defense and general duty use. However, some competition shooters want more accurate barrels, which is why some aftermarket companies make “match grade barrels,” which can have a different rifling profile to perform perfectly with a specific bullet weight; factory barrels, on the other hand, are designed to offer good accuracy with a wide range of bullet profiles.
