Zaffiri Precision G19 Gen 1-4 Flush and Crown Barrel

The Zaffiri Precision G19 Gen 1-4 Flush and Crown Barrel is a precision-engineered upgrade designed for superior performance, reliability, and style. Perfect for Glock^® 19 owners looking to enhance accuracy or complete a custom build, this barrel combines match-grade quality with a clean, flush-fitting design that blends seamlessly with the slide.

Machined from premium 416R stainless steel, each barrel is heat-treated and stress-relieved to a Rockwell hardness of RC 40-42 for extended durability and performance under hard use. The bore and chamber are polished to ensure smooth operation and consistent feeding with a wide variety of ammunition types including lead, plated, and jacketed rounds.

The Zaffiri Precision G19 Gen 1-4 barrel features a Flush and Crown profile, meaning it sits flush with the end of the slide while the muzzle is recessed into a protective crown, offering enhanced durability and a refined look. It is optimized for Gen 1–4 Glock^® 19 pistols and will be too short for use with Gen 5 slides due to length and locking lug differences.

Choose from three premium finishes to match your build:

• Black Nitride: Offers sleek looks with high resistance to wear and corrosion
• Stainless: Clean, raw finish for a timeless appearance
• Titanium Nitride (TiN) Gold: Bold, durable, and eye-catching with enhanced lubricity
