The Zaffiri Precision ZAF BBL For GLK 19 G3 4.5" TB Gold is a match grade, threaded 9mm barrel designed as a drop-in upgrade for Glock 19 pistols across Gen 3–5. Machined from 416R stainless steel and finished in a durable gold titanium nitride coating, it offers tighter tolerances than factory barrels for improved consistency and accuracy. The 4.5" length with 1/2x28 threads allows easy attachment of compensators or suppressors while maintaining a sleek profile.

The polished chamber and bore, target crown, and smooth feed ramp support dependable performance with a variety of 9mm loads. As a drop-in accessory from Zaffiri Precision, it reflects the manufacturer’s focus on careful machining and thoughtful design for custom Glock builds.
