FAQ
Is this a true drop-in barrel, or will it require gunsmith fitting?
This is engineered as a drop-in barrel for standard Glock 19 pistols. It should install directly into your OEM slide and frame without modification for reliable function. Always check for proper lock-up and feeding after installation.
What is the advantage of the “Radio Active” PVD coating?
Beyond its distinctive appearance, PVD (Physical Vapor Deposition) coating is significantly harder and more wear-resistant than traditional finishes like nitride or TiN. It provides excellent lubricity, reduces friction, and protects against corrosion and abrasion far better than standard coatings.
