If you're serious about customizing your Glock, a Glock 19 threaded barrel is essential. These barrels come with a 1/2x28 thread pitch—the standard for most 9mm suppressors and muzzle devices—giving you more flexibility in how you set up your firearm.
At 3CR Tactical, our threaded barrels feature precision-cut threads for a snug, secure fit, and many come with a thread protector to prevent damage when not in use. Whether you’re aiming for reduced recoil, improved shot control, or just a tactical look, a threaded barrel unlocks a world of customization.
Let’s talk about fluting—it’s not just for aesthetics. Fluted Glock 19 Gen 5 barrel options cut down on weight while increasing surface area, meaning better heat dissipation and a more balanced firearm.
For high-volume shooters, this translates to improved consistency over long shooting sessions. We offer fluted barrels in a variety of finishes, including titanium nitride (gold), black nitride, and stainless steel, so you can get a performance boost without sacrificing looks. These aftermarket barrels provide both function and form, giving your Glock pistols a sleek upgrade.

A Glock 19 barrel with porting is designed to reduce recoil and muzzle rise by venting gases upward. The result? Faster follow-up shots and improved target tracking. Ported barrels are a favorite among competitive shooters and anyone who wants to maximize control during rapid fire.
We carry premium options from trusted names like Agency Arms, Zaffiri Precision, and Faxon Firearms—each designed to give you an edge when it counts. Adding a compensator can further fine-tune recoil management, ensuring you stay on target shot after shot.
Why limit yourself to one caliber? Our Glock 19 threaded barrel and standard conversion barrels allow you to swap between 9mm, .40 S&W, and .357 SIG with a quick and easy barrel change.
Conversion barrels are perfect for shooters who like to experiment with different calibers, whether for training, cost-saving, or personal preference. Precision-machined to work flawlessly with Glock slides and magazines, these barrels open up new possibilities without requiring a new firearm.
