Zaffiri Precision Zp.17Btbn 9Mm Glock 17 Gen1-4 4.99" Black 416R S/S

A Zaffiri Precision match-grade barrel for Glock 17 Gen 1-4 pistols doesn't just fit—it transforms your shooter's experience. This 4.99" threaded 9mm barrel is engineered for the kind of precision and reliability that separates casual plinkers from serious shooters. Built from 416R stainless steel, stress-relieved and heat-treated to RC 40-42 hardness, it's a drop-in upgrade that works with lead, plated, or jacketed ammunition without fuss or fitting. If you're chasing tighter groups at distance, building a suppressed 9mm, or simply want the confidence of American-made quality in your carry or range gun, this is the kind of upgrade that pays dividends round after round.

The threaded muzzle is cut to 1/2 x 28—the standard for 9mm suppressors and brakes—and Zaffiri includes a thread protector so you're ready to run it unsuppressed or swap on your can without hunting for a cap. The 1/10 twist rate handles modern 9mm loads across the board, and the distinctive "ZP" logo machined into the left side of the lockup marks it as serious iron. Installation is straightforward: remove your factory barrel, drop this one in, and you're shooting. No gunsmithing required.

Zaffiri Precision barrels have earned their reputation among competitive shooters and tactical professionals for holding tight tolerances and delivering shot-to-shot consistency. This one is no exception—it's the kind of component that makes you wonder why you didn't upgrade sooner. Just remember: threaded barrels carry legal restrictions in some jurisdictions, so confirm your local laws before ordering.
