Zaffiri Precision Aftermarket Barrel for Glock 17 Gen 1-4 – Black Nitride Finish

This Zaffiri Precision aftermarket barrel is designed as a direct replacement for factory Glock 17 barrels in Gen 1 through Gen 4 pistols. Engineered for improved accuracy and consistent lock-up, this barrel offers shooters a precision-machined upgrade that maintains reliable function with factory and aftermarket slides. The match-grade bore and chamber are cut to tighter tolerances than OEM specifications, which can reduce group sizes at typical defensive and competition distances.

Constructed from 416R stainless steel and treated with a black nitride finish, this barrel resists corrosion and wear while maintaining a low-friction surface that aids in cleaning. Installation is drop-in with no fitting required on standard Glock 17 Gen 1-4 frames and slides. The barrel uses conventional rifling and is rated for jacketed and lead ammunition. Thread pitch is standard 1/2x28 if threaded models are selected; confirm your specific variant before purchase if you plan to mount a suppressor or compensator.
