Zaffiri Precision ZP.17G5BTG 9mm Fits Glock 17 Gen 5 Gold Stainless Steel

The Zaffiri Precision ZP.17G5BTG is a 9mm barrel engineered for the Glock 17 Gen 5, built for shooters who want to upgrade their carry or duty gun's accuracy and longevity. This isn't a cosmetic swap—a quality aftermarket barrel can tighten groups, reduce wear on the frame, and give you a platform for threading if you're running a suppressor. Zaffiri barrels are built with precision tolerances and finished in durable titanium nitride for corrosion resistance and extended service life. The gold stainless steel finish gives it a distinctive look while the 4.99" length maintains the Glock 17's handling characteristics and sight radius.

If you're building a tack-driver 9mm or refreshing a duty gun that's seen heavy use, a precision barrel is one of the smartest upgrades you can make. The 1/2x28 thread pattern on this barrel integrates seamlessly with standard 9mm suppressors and muzzle devices, so it's ready for can-hosting if that's in your future. Installation is straightforward for anyone with basic gunsmithing experience or a competent armorer.

Zaffiri's reputation in the custom Glock community is solid—they spec their barrels to tight tolerances and don't cut corners on materials. This is a no-BS upgrade that delivers measurable improvements in reliability and shot placement without the hype.
