Product Description The Zaffiri Precision Match Grade Barrel for Glock 23 Gen 1-3 is a premium drop-in upgrade built for .40 S&W shooters who refuse to compromise on accuracy or reliability. Precision-machined from 416R stainless steel and stress relieved with heat treatment to RC 40-42, this barrel is engineered for long-lasting durability and consistent performance. A polished feed ramp promotes smooth, reliable chambering of every round, while the target crown and oversized lockup area work together to deliver tighter groupings downrange. The flush-and-crown profile sits perfectly even with the end of the slide, maintaining a clean factory appearance. A large ZP logo is machined directly on the port side of the lockup, giving your Glock a distinctive custom look. Manufactured in the United States, this barrel is designed to work with lead, plated, and jacketed ammunition right out of the box.
