Zaffiri Precision
The Zaffiri Precision barrel for Glock 19 Gen 1-4 is a match-grade upgrade that transforms your pistol's accuracy and reliability without requiring a gunsmith. Built from 416R stainless steel and stress-relieved to exacting standards, this non-threaded barrel drops into your Glock 19 (Gen 1 through Gen 4) and runs reliably with lead, plated, or jacketed ammunition. Whether you're a competitive shooter chasing tighter groups or a serious defensive carrier looking to wring every bit of performance from your EDC, a quality barrel upgrade is one of the most effective modifications you can make.
Zaffiri Precision's attention to detail shows in the polished feed ramp, which promotes smooth ammunition feeding and reduces the risk of failures to feed. The target crown and oversized lockup area ensure consistent bullet seating and barrel timing, both critical for accuracy. Heat treatment to RC 40-42 hardness gives you a barrel that handles demanding use and stands up to repeated firing without losing its dimensional integrity. The distinctive ZP logo is machined into the lockup area—a small mark of pride from a builder that focuses on the details most shooters never see but always feel.
This is a flush-crown, non-threaded configuration, which means the barrel crown finishes even with the slide's end. That makes it compatible with standard Glock slide racking and aftermarket slides without complications. Made in the USA, this barrel represents the kind of precision manufacturing that separates match-grade parts from run-of-the-mill replacements. If you're upgrading from a factory Glock 19 barrel and want measurable improvement in shot placement, this is a legitimate performer.
