Ballistic Advantage Premium Series — 9mm, 4.5" Threaded Barrel (1/2×28), Spiral Fluting, Fits Glock® 19 Gen 3–5, PVD Iridescent “Rainbow” Finish | Model BAPSG195T3W | UPC 819747026200
Give your G19 a precision core and a head-turning look. The Ballistic Advantage Premium Series 9mm 4.5" Threaded Barrel brings match-grade accuracy, spiral fluting for weight reduction and heat dissipation, and a brilliant PVD Iridescent (Rainbow) finish to your Glock® 19 Gen 3–5. With standard 1/2×28 threads for comps, brakes, or suppressor mounts (where legal), this drop-in barrel is built to run hard and shoot tight—on the range, in competition, and during training blocks.
Why Upgrade to the BA Premium 4.5" Threaded Barrel
Match-grade 9mm barrel engineered for Glock 19 Gen 3–5 compatibility
4.5" length (extended beyond factory) for added velocity and thread shoulder
1/2×28 muzzle threads for popular comps and suppressor devices*
Spiral fluting reduces weight, boosts surface area for cooling, and adds a premium aesthetic
PVD Iridescent (Rainbow) finish for exceptional wear resistance, lubricity, and striking style
Drop-in fit for most factory slides—no gunsmithing typically required
Ballistic Advantage Premium Series quality known for consistent, repeatable accuracy
*Always verify device alignment and local laws regarding threaded-barrel and suppressor use.
Precision You Can Feel
Ballistic Advantage tunes chamber geometry, crown, and rifling to deliver reliable feeding and repeatable point of impact with common range and defensive loads. Expect clean lockup, smooth cycling, and groups that tighten up as you do your part. The extra barrel length helps wring out a bit more velocity while retaining the G19’s compact handling.
Spiral Fluting: Form Meets Function
The helical flutes aren’t just for looks. Spiral fluting strategically removes material to reduce out-front weight and increase cooling surface area, helping the barrel manage heat during high-round-count training without feeling nose-heavy. It also adds structural rigidity for better harmonic response shot to shot.
PVD Iridescent “Rainbow” Finish
Beyond the eye-catching spectrum sheen, Physical Vapor Deposition (PVD) provides a hard, low-friction surface that resists wear, corrosion, and carbon adhesion. That means easier cleaning, smoother operation, and a finish that stays vibrant after long training days.
Threaded for Versatility
With standard 1/2×28 threads and a proper shoulder, you can install the most popular compensators, thread protectors, and suppressor mounts (where permitted). The extended length offers ample room for devices while maintaining reliable slide travel.
Important: If you intend to run a suppressor, always confirm concentricity with a bore alignment rod and use a quality piston/Nielsen device as required by your can’s manufacturer.
Ideal Use Cases
Competition & range: Faster follow-ups with comps and flatter tracking
EDC training: Match-grade consistency for skill development with your carry platform
Pistol-caliber carbines (PCC) companion: Optimize trajectory and POI alignment across systems
Customization builds: Premium performance with a finish that stands out
Compatibility
Pistol models: Glock® 19 Gen 3, Gen 4, Gen 5 (most factory and many aftermarket slides)
Caliber: 9×19mm (9mm Luger)
Muzzle devices: 1/2×28 threaded accessories
Some slides with ultra-tight tolerances or unusual internals may require minor fitting. Test function with your specific slide, recoil spring, and ammunition.
Installation Tips (General Guidance)
Unload and clear the pistol; remove slide, recoil spring, and existing barrel.
Drop in the BA barrel and cycle the slide by hand to verify smooth lockup.
Install a thread protector when running without a device to protect the crown and threads.
If adding a compensator or suppressor, torque to manufacturer spec and confirm reliable cycling with your chosen recoil spring and ammo.
Care & Maintenance
Clean bore and chamber on a sensible schedule; the PVD surface helps fouling release more easily.
Lightly oil locking surfaces; avoid abrasive media on the finish.
Inspect threads and devices periodically for tightness and carbon buildup.
