Zaffiri Precision Barrel for Glock 17 Gen 3 9mm 4.37" – Black Nitride Finish

The Zaffiri Precision barrel for Glock 17 Gen 3 pistols delivers match-grade accuracy in a direct drop-in replacement. Precision-machined to tighter tolerances than factory barrels, this 4.37-inch barrel improves shot-to-shot consistency and groups while maintaining full reliability with all factory and aftermarket slides. The upgraded barrel is ideal for shooters looking to enhance accuracy for competition, duty carry, or serious range work without modifying the pistol's footprint.

Machined from 416R stainless steel and finished with black nitride, this barrel offers corrosion resistance and reduced friction for smooth cycling. The standard 1:10 twist rate stabilizes a wide range of 9mm projectile weights. Chambered in 9mm Luger with conventional rifling, it's compatible with jacketed, plated, and lead projectiles. Installation requires no gunsmithing—simply field strip the pistol and swap the barrel. Not compatible with Gen 4 or Gen 5 Glock models.
