G17 Gen 1-4 Barrel Threaded Tin

The Zaffiri Precision G17 Gen 1-4 Barrel Threaded Tin is a match-grade drop-in barrel upgrade engineered for Glock 17 pistols across generations 1 through 4. Built by shooters who demand reliability in duty and competition environments, this threaded barrel transforms your platform into a suppressor-ready firearm without gunsmithing or permanent modifications. The titanium nitride finish delivers both corrosion resistance and a professional appearance on the shooting line.

Precision manufacturing and tight tolerances define Zaffiri's reputation in the aftermarket barrel space. This barrel features a 1/10 twist rate optimized for standard 9mm Luger projectiles and a 5-inch length that maintains full sight radius while improving velocity and accuracy over factory profiles. The titanium nitride (TiN) coating reduces friction, improves wear resistance, and resists environmental corrosion—critical for duty weapons or ranges with harsh conditions. The threaded muzzle accepts standard 1/2x28 suppressor mounts, enabling subsonic and supersonic suppressed shooting without adapter sleeves.

Law enforcement professionals, competitive shooters, and civilian operators benefit from this straightforward upgrade path. Installation requires only barrel removal and drop-in—no fitting or headspace concerns across compatible Glock 17 Gen 1-4 models. Whether preparing for a suppressor purchase, upgrading accuracy in match play, or modernizing a duty weapon, this match-grade barrel delivers measurable improvement in shot grouping and reliability. Compatible with standard Glock 17 holsters, slides, and frame assemblies, making it an ideal first modification for shooters seeking performance gains without platform changes.
