Glock 39893 9Mm Fits 17 Gen4 Black Steel

The Glock 39893 is a factory OEM threaded barrel for the Glock 17 Gen4, chambered in 9mm and finished in black steel. This barrel opens up suppressor compatibility for shooters who want to run their Gen4 G17 with a can—whether for range sessions, home defense, or reduced-noise training. It's the straightforward path to a quieter, more versatile pistol without swapping frames or getting creative with adapters.

Like all Glock barrels, the 39893 uses the company's signature hexagonal rifling, which is proven across millions of rounds for reliability and accuracy. The 4.875-inch barrel length maintains the classic G17 profile and ergonomics you already know. The M13.5X1LH threading is right-hand twist with a 1 in 9.84-inch twist rate, designed to stabilize the full spectrum of common 9mm ammunition.

The barrel ships with a thread protector, so you're ready to go out of the box while you source a suppressor, or swap it straight onto your existing slide. If you shoot suppressed or are considering it, this Glock 17 Gen4 threaded barrel removes the guesswork—it's genuine Glock parts quality, drop-in fitment, and the same durability you'd expect from OEM gear.
