A drop-in barrel upgrade for your Gen 5 Glock 17, the Grey Ghost Precision 9mm threaded barrel delivers match-grade accuracy out of the box. Built from 416R stainless steel—a premium material favored for precision barrels—this replacement barrel holds tolerances to +/− 0.003 inches and comes chambered to SAAMI specification. Whether you're dialing in suppressor-ready accuracy at the range or upgrading your carry gun's reliability, this barrel installs without gunsmithing and performs as a true precision component.

The 1×10 twist rate is optimized for 9mm ballistics, and the black nitride finish provides durable protection against corrosion and wear while staying true to the Glock aesthetic. Threading is already cut, so you can run a suppressor or muzzle device on day one. Grey Ghost Precision engineered this as a match-grade drop-in, meaning it's built to tighter specs than factory Glock barrels and designed to improve shot consistency without modifications to your pistol.

At just 5 ounces, the weight doesn't upset your gun's balance or cycling characteristics. This is a straightforward upgrade: remove the factory barrel, install the Grey Ghost, and you're running a precision 9mm platform.

Frequently Asked Questions

Will this barrel work with a suppressor?

Yes. The barrel comes pre-threaded and ready to accept a suppressor or other muzzle device. You'll need the correct adaptor for your specific suppressor, but the threading is done.

Do I need a gunsmith to install this?

No. This is a drop-in barrel designed to install without professional help. Remove your factory barrel and install the Grey Ghost in its place.

What's the advantage of match-grade over a factory Glock barrel?

Match-grade barrels hold tighter tolerances—in this case +/− 0.003 inches—which means more consistent chamber dimensions and better accuracy potential. The 416R stainless steel and precision manufacturing translate to improved shot-to-shot consistency.

Yes, this barrel is specifically designed for the Gen 5 Glock 17 and drops in as a direct replacement.
