Zaffiri Precision Threaded Barrel for Glock 17 Gen 5 – 4.97" Black Nitride

This Zaffiri Precision threaded barrel replaces the factory Glock 17 Gen 5 barrel with a match-grade option designed for improved accuracy and suppressor compatibility. The 4.97-inch length maintains the standard service profile while adding 1/2x28 threading at the muzzle for mounting suppressors, compensators, or flash hiders. Shooters looking to run a suppressed G17 or add a muzzle device will find this barrel provides a reliable, drop-in upgrade.

Machined from 416R stainless steel and finished with black nitride for corrosion resistance and reduced friction, this barrel features conventional rifling and tight chamber tolerances. Installation is straightforward—remove the factory barrel and slide this unit into place. The barrel is sized specifically for Gen 5 Glock 17 pistols and will not fit earlier generations due to differences in lug geometry. Thread protector included.
