Zaffiri Precision BARREL FOR GLOCK 17 GEN5 TIN

A Zaffiri Precision barrel for Glock 17 Gen5 gives your duty or competition pistol a genuine upgrade path without the gunsmith visit. Match-grade construction and precision machining transform how your G17 performs downrange—tighter groups, improved reliability, and the confidence that comes from a drop-in component built to exacting standards. Whether you're a defensive shooter, competition enthusiast, or someone who simply demands better accuracy from their carry gun, this stainless steel barrel replaces the factory tube with purpose-built performance.

Zaffiri builds these barrels from 416R stainless steel, a material prized in precision gunmaking for its machinability and longevity. The barrel is stress relieved and heat treated to RC 40–42 hardness, ensuring dimensional stability and resistance to wear. A polished feed ramp smooths the round's transition from magazine to chamber, reducing friction and feeding inconsistencies. The target crown—a precision-cut muzzle face—protects the barrel's throat and helps group shots tighter. An oversized lock-up area ensures the barrel seats consistently in the slide's barrel lug, minimizing play and shot-to-shot variation.

Installation is straightforward: field-strip your G17 Gen5, remove the factory barrel, and drop this one in. No fitting, no reaming, no headspace guesswork. The Gen5 design works with all standard Glock 17 Gen5 frames and slides. Whether you're running it for daily carry, range training, or matches, you'll notice the difference in handling and accuracy. This is the kind of no-nonsense upgrade that Glock shooters have trusted for years.
