Zaffiri Precision Zp.19Btbn 9Mm Glock 19 Gen 1-5 4.60" Black 416R S/S

The Zaffiri Precision ZP.19BTBN is a match-grade threaded barrel built for shooters who demand precision upgrades for their Glock 19. Whether you're running a Gen 1 through Gen 5 frame, this 416R stainless steel drop-in barrel delivers the accuracy and durability that separates a duty gun from a competition or suppressor-ready platform. Zaffiri's reputation for tight tolerances and hand-fit quality makes this a straightforward way to elevate your pistol's performance without complexity.

Built from 416R stainless steel and stress-relieved to exacting standards, this barrel is hardened to RC 41—a specification that balances wear resistance with the toughness needed for sustained fire. The polished feed ramp ensures smooth, reliable cycling whether you're burning through lead, plated, or jacketed rounds at the range or in competition. The target crown and oversized lockup area are hallmarks of Zaffiri's precision manufacturing, and they directly translate to tighter groups and consistent headspace lockup across Gen variants.

This is a threaded barrel designed for shooters planning suppressor use or muzzle device attachment. It threads at 1/2 x 28—the industry standard for 9mm pistols—and includes a thread protector so you're ready out of the box. The 4.60-inch length threads as specified; note that threaded pistol barrels are subject to local and federal regulations, so confirm legality in your area before ordering. Made in the USA, this barrel carries Zaffiri's commitment to domestic manufacturing and quality control. Simply drop it into your Glock 19 slide and you're done—no fitting, no gunsmithing.
