Zaffiri Precision Threaded 9mm Luger 4.60" 1:10 1/2x28 Black Nitride Drop-In Barrel - Fits Glock 19 Gen 1-5

The Zaffiri Precision BA-G19G15-TH-BN is a drop-in, match-grade threaded barrel for the Glock 19 in 9mm Luger. Cut from 416R stainless steel and finished in a low-reflectivity, corrosion-resistant Black Nitride coating, this barrel drops into the slide of a Glock 19 Gen 1-5 (also compatible with the Ruger RXM) without fitting and delivers the bore quality and accuracy expected of a premium aftermarket upgrade.

Measuring 4.60" long with a 1:10 rate of twist that stabilizes the full range of common 9mm bullet weights, the muzzle is pre-machined with 1/2x28 threading for suppressor or compensator mounting, and a thread protector is included to keep the threads protected during use. A polished feed ramp helps ensure reliable chambering from factory magazines, while the Black Nitride surface treatment reduces friction and makes routine cleaning straightforward.

Whether you're building out a suppressed carry Glock, dialing in a range pistol, or replacing a worn factory barrel, this Zaffiri Precision threaded barrel brings match-grade performance and modern muzzle threading to one of the most popular compact 9mm platforms ever made.
