Drop-in 9mm replacement barrel for Glock 17 Gen 3-4 frames. Machined from 4150 chromoly steel and finished in titanium nitride (TiN) — gold satin sheen, hardened surface, low-friction face that wipes clean and resists carbon buildup between range trips.
Standard non-threaded muzzle with a flush crown — accurate, clean use right out of the box, no muzzle device required.
Features:
Verify your slide is a Glock 17 Gen 3-4 pattern before install — Gen 5 barrel lockup is dimensionally different and is not guaranteed to fit. Hand-cycle a dummy round to confirm headspace before live fire.
Finish note: The TiN coating will show wear at metal-to-metal contact points — primarily the locking lug face and barrel hood — over time. This is normal and does not affect function or accuracy.
