Ballistic Advantage Premium Series Threaded Barrel for Glock 19 Gen 3-5 | Black

The Ballistic Advantage Premium Series Threaded Barrel for Glock 19 Gen 3-5 adds suppressor-ready flexibility to one of the most widely used compact pistol platforms. Its streamlined exterior and Black QPQ finish create a practical, understated configuration for carry builds, range pistols, and factory-style upgrades where durability and broad compatibility take priority.

Measuring 4.5 inches, the barrel extends beyond the slide and provides 1/2×28 muzzle threads for compatible 9mm suppressors, compensators, and other muzzle devices. Ballistic Advantage includes a standard thread protector with O-rings, which help maintain tension and keep the protector secure while the muzzle threads are covered.

The barrel is machined from hardened 416R stainless steel for strength, toughness, dimensional stability, and resistance to corrosion. A Black QPQ treatment hardens the exterior surface and provides durable protection against friction, carbon, moisture, and the wear associated with frequent cycling and regular handling.

Compatibility with Glock 19 Gen 3 through Gen 5 pistols makes this Premium Series barrel a versatile replacement option across multiple slide and frame generations. Its smooth profile also provides a more traditional appearance than Ballistic Advantage’s Spiral- and Bomber-fluted configurations.

Each bore is honed, lapped, and tumbled to remove manufacturing imperfections and create a smooth internal surface. The chamber is manufactured to SAAMI specifications, while a 1:10 twist supports commonly used 9mm projectile weights. Ballistic Advantage specifies that no manufacturer-prescribed break-in period is required.
