Zaffiri Precision Bbl Threaded TiN Barrel for Glock 17 Gen 1-5

The Zaffiri Precision threaded barrel for Glock 17 is a precision-engineered replacement barrel designed for shooters who want to run suppressors or other threaded muzzle devices on their Gen 1–5 Glock 17 pistols. Built with a TiN (titanium nitride) finish, this barrel combines durability with a distinctive gold aesthetic while delivering the reliability you need at the range, in competition, or in the field. At 4.49 inches, it maintains the slide length of your factory setup while giving you the threading you need to accessorize—a straightforward upgrade for anyone looking to add suppressor-ready capability to their carry or competition gun.

Zaffiri Precision is known for tight tolerances and quality control, and this barrel reflects that reputation. The 1/2x28 threading is the standard for 9mm pistols, so you'll have no trouble finding compatible suppressors, flash hiders, or brakes. The TiN finish is harder and more corrosion-resistant than standard mil-spec phosphate, which means better protection against wear and rust—especially valuable if you're running a suppressor and dealing with more powder residue and backpressure in regular use.

Installation is straightforward for anyone comfortable taking down their Glock, and the barrel is compatible across the entire Gen 1–5 lineage. Whether you're a suppressor enthusiast, a competitive shooter building out a race gun, or someone who just wants the option to run a can down the road, this is a no-nonsense upgrade that doesn't compromise fit or function.

Frequently Asked Questions

Will this barrel work with my Glock 17 generation?

Yes. This Zaffiri Precision barrel is compatible with Glock 17 pistols from Gen 1 through Gen 5, so regardless of which generation you own, it will fit and function.

What suppressors will work with the 1/2x28 threading?

The 1/2x28 thread pitch is the industry standard for 9mm pistols, so you'll have access to the widest selection of suppressors, flash hiders, and muzzle devices on the market. Check your suppressor manufacturer's specifications to confirm compatibility.

How do I install this barrel?

Installation requires field-stripping your Glock 17. If you're comfortable taking apart your pistol for routine cleaning, you can install this barrel yourself. If you're not experienced, we recommend having a gunsmith handle the swap to ensure proper function and headspace.

Why choose TiN finish over standard barrel coating?

TiN (titanium nitride) is significantly harder and more corrosion-resistant than standard phosphate finishes, which means better wear resistance and longevity—especially useful if you're running a suppressor regularly and exposing the barrel to additional heat and residue.
