Zaffiri Precision Barrel Features The Zaffiri Precision Barrel is machined from stainless steel and finished in a vivid Gold TiN coating that sets it apart from a standard factory barrel while adding a layer of corrosion and wear resistance over bare steel. Designed as a direct fit for the Glock 17 Gen3 it maintains the 4.99 inch barrel length and a 1:10 twist rate that work reliably with lead plated and jacketed ammunition alike. The 1/2x28 threaded muzzle opens up the Glock 17 to compensators flash hiders and suppressors and a thread protector is included to keep the threads clean and the profile tidy when no muzzle device is installed. At 6 ounces the barrel adds negligible weight to the pistol while delivering the fit and finish of a precision aftermarket part. Replacing a factory barrel with a precision made option like this one is a common upgrade path for Glock 17 Gen3 owners chasing tighter tolerances and a more refined chamber and bore finish. The Gold TiN coating is not just cosmetic as titanium nitride coatings are known for their hardness and reduced friction which can translate into smoother cycling over the life of the barrel. A drop in fit means no additional machining or fitting is required for most Glock 17 Gen3 pistols running factory or compatible aftermarket slides. This Zaffiri Precision Barrel in Gold TiN is available for sale at GrabAGun for Glock 17 Gen3 owners who want to upgrade both the look and the function of their pistol.
