The Zaffiri Precision match-grade drop-in barrel is a direct replacement for the Glock 17 Gen 3 factory barrel, machined from 416R stainless steel and finished in black for a stealth build inside a slide window or under an assembled cut. The flush-and-crown profile sits even with the front of the slide with an inward crown shape that adds a visual highlight without extending overall length.
Specs & features:
Verify slide generation before install; this barrel is cut for Gen 3 lockup geometry and is not a drop-in for Gen 4 or Gen 5 without a matching slide. Run a factory-weight recoil spring during break-in and check timing after the first 100–200 rounds — tight-tolerance match barrels sometimes prefer a slightly heavier spring to settle into consistent unlocking.
