FAQ
Is this a drop-in barrel for my Glock 19?
Yes, this barrel is designed as a drop-in upgrade for most factory-stock Glock 19 pistols. Always check function with your specific ammunition after installation.
Does the copper coating wear off?
The copper finish is a Physical Vapor Deposition (PVD) coating, which is bonded at a molecular level to the stainless steel. It is highly resistant to holster wear, solvents, and corrosion, making it far more durable than any painted or plated finish.
