Faxon Firearms Match Series Flame Fluted Drop In Barrel 9mm 4 02 Inch Glock 19 19X 45 Black Nitride MPN GB910N19LGQ N SKU FXGB910N19LGQ N UPC 816341022522
Product Description
The Faxon Firearms Match Series Flame Fluted® Drop-In Barrel (SKU: GB910N19LGQ-N / UPC: 816341022522) delivers a masterclass upgrade in mechanical accuracy, structural cooling, and custom aesthetics for Glock 19, 19X, and 45 platforms. Manufactured completely in-house in Greater Cincinnati, Ohio, this barrel transforms standard defensive sidearms and competition handguns into precision-engineered instruments featuring enhanced lockup, strict bore concentricity, and premium match-grade reliability.
Every Match Series barrel begins as a solid bar of certified 416-R stainless steel that is gun-drilled, reamed, and conventionally button-rifled with a 1:10 twist rate and six distinct lands and grooves. Unlike factory polygonal bores that strictly prohibit unjacketed projectiles, Faxon’s conventional rifling safely stabilizes everything from cast-lead handloads to premium jacketed hollow points and heavy subsonic suppressible projectiles. The barrel blank is stress-relieved in-house following the rifling operation to eliminate core metal tension, qualify-turned to guarantee absolute bore alignment, and treated inside and out with a Salt-Bath QPQ Nitride finish for extreme corrosion immunity and surface hardness.
Externally, the patented Flame Fluted® profile removes dead reciprocating slide weight while drastically increasing exposed surface area to accelerate thermal dissipation during sustained fire strings. At the terminal end, a precision-cut 11-degree target crown ensures uniform propellant gas dispersion behind the projectile upon muzzle exit. Engineered with better-than-factory locking lug tolerances, this non-threaded 4.02-inch barrel drops cleanly into factory-spec slides while maintaining standard holster clearance and duty-grade cycling dependability.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Engineered for direct drop-in fitment across Glock 19 (Generations 1–5), Glock 19X, and Glock 45 slides. CRITICAL FITMENT NOTICE: This barrel will NOT fit Slimline frames (Glock 43, 43X, or 48), full-size platforms (Glock 17, 34, 17L), or subcompact Glock 26 slides. Do NOT install this barrel into Glock 23 (.40 S&W) or Glock 32 (.357 SIG) slides. While engineered for direct drop-in assembly on factory Glock and quality OEM-spec aftermarket slides, hand-fitting may be required on out-of-spec custom aftermarket slides. Prior to final slide reassembly, apply a micro-film of synthetic gun oil across the top barrel hood, forward locking lug face, and circumferential muzzle band.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Depress the trigger in a safe direction, retract the slide approximately 1/10th of an inch, pull down both sides of the frame slide lock, and slide the upper assembly forward off the receiver rails.
- Compress the recoil spring assembly slightly forward toward the muzzle, lift the rear base off the barrel crescent lug, and remove it from the slide channel.
- Lift the factory barrel upward by its locking lug, draw it slightly rearward, and extract it through the slide ejection port.
- Insert the Faxon Match Series Flame Fluted barrel into the slide through the ejection port, seat the barrel hood squarely against the breech face, reinstall the factory recoil spring assembly into the lower lug notch, remount the slide to the frame, and conduct a full five-point manual safety and function check.
Key Features
- Match-Grade 416-R Stainless Steel: Stress-relieved ordnance steel delivers tight bore tolerances, enhanced pressure handling, and exceptional thermal stability under rapid fire.
- Conventional 6-Groove Button Rifling: 1:10 twist rate handles the complete spectrum of 9mm ammunition, including cast lead, frangible, polymer-coated, and bonded jacketed rounds.
- Patented Flame Fluted® Geometry: Milled flutes reduce reciprocating slide mass while increasing surface area for rapid cooling and unmistakable custom styling.
- Salt-Bath QPQ Nitride Finish: Penetrates the core metal inside and out to maximize surface hardness, corrosion resistance, and slick cycling lubricity.
- 11-Degree Recessed Target Crown: Shields critical muzzle rifling from field impacts while delivering symmetrical propellant gas release for tighter groupings.
- Direct Drop-In Integration: Calibrated with tight match-grade tolerances that require zero gunsmithing on factory-spec Glock slides.
