The Ballistic Advantage Premium Series 9mm Luger barrel (brand part number BAPSG175T1Q) is a drop-in replacement built specifically for the Glock 17 Gen 5. Machined from hardened 416R stainless steel and finished in QPQ black nitride, this fluted barrel pairs corrosion resistance with a lighter overall profile than a factory barrel. The 1/2×28 threaded muzzle accepts a compensator or suppressor once you’re ready to add one, and a thread protector ships with the barrel so the threads stay clean until then. Whether you’re building a competition-ready G17 or just want a more durable bore, this barrel is a straightforward accuracy and durability upgrade.

Key Specifications

• Chambered in 9mm Luger, the standard defensive and competition round for the Glock 17 platform.
• Barrel length of 5 inches extends slightly beyond the factory 4.49-inch barrel to accommodate the threaded muzzle, while still installing as a true drop-in fit.
• Rate of twist is 1:10 inches, tuned for standard-weight 9mm bullets.
• Machined from hardened 416R stainless steel for long-term strength and corrosion resistance.
• Finished in QPQ black nitride, which improves surface hardness and wear resistance over a bare steel finish.
• Features a fluted profile that sheds weight while retaining rigidity along the barrel length.
• Muzzle is cut with 1/2×28 threads, ready for a compensator or suppressor mount.
• Weighs approximately 3.2 ounces, keeping muzzle weight manageable for fast follow-up shots.
• Built as a direct drop-in fit for the Glock 17 Gen 5, requiring no gunsmithing to install.
• Ships with a standard thread protector to keep the muzzle threads protected until you mount a device.
