FAXON FX19X HELLFIRE COMPACT 9MM PISTOL
Faxon
FX-19X Gen 2 • Compact Slide • Full-Size Frame • Threaded Match Barrel • Made in Ohio
FAXON FX-19X HELLFIRE COMPACT 9MM PISTOL — FX-19X-HF-02
The Faxon FX-19X Hellfire Compact 9mm Pistol is the flagship build in the all-new FX-19 Gen 2 lineup — pairing a full-size FX-19X Gen 2 frame with the aggressive Hellfire compact slide and a Match Series flame-fluted threaded barrel for suppressor and compensator hosts. Unlike a slide kit or aftermarket build, this is a fully assembled, serialized firearm that ships ready for an FFL transfer.
Full-size frame, compact slide — the best of both worlds. The FX-19X Gen 2 frame gives you a full hand grip and 17+1 capacity from standard Glock® 17 magazines, while the compact Hellfire slide keeps the gun fast and concealable. Run it in any Glock® 19X / Glock® 45 style duty rig, retain your Glock® 17 Gen 3 frame accessories, Glock® 19 Gen 3 slide parts, and feed it from any Glock® 17 magazine you already own.
The heart of the build is the Faxon Match Series Flame-Fluted Threaded Barrel for Glock® 19 Gen 2-5 — threaded 1/2x28 for direct suppressor and EXOS® compensator use, machined in-house from 416-R stainless steel, flame-fluted for weight reduction and improved heat dissipation, and finished with a durable QPQ nitride treatment inside and out. It's the same Match Series quality our customers run as a drop-in upgrade in their stock Glock® 19 Gen 3 pistols, factory-installed here.
The slide is the new Faxon Hellfire Slide for Glock® 19 Gen 3 & FX-19 — aggressive serrations engineered for positive purchase under the worst conditions and the boldest profile in the Faxon lineup. It ships with a Trijicon RMR® footprint optic cut, complete with removable cover plate so you can run irons today and add an optic tomorrow with no extra parts to buy. Sights are Night Fision® Optics-Ready Stealth Series Night Sights — tritium front, lower 1/3 co-witness with any RMR-footprint optic.
✔ Best for: shooters who want suppressor or compensator capability out of the box, full-size frame ergonomics with compact slide handling, 17+1 capacity from standard G17 magazines, premium Match Series barrel quality, and the most feature-complete build in the FX-19 Gen 2 lineup.
✘ Not for: shooters who need the most concealable carry footprint (see the compact-frame FX-19 Hellfire Gen 2), shooters who don't need a threaded barrel and want to save (see the FX-19X Patriot with non-threaded Match barrel), or buyers in states with handgun or magazine capacity restrictions that prohibit FX-19X shipment.
? Legal note: This is a complete, serialized firearm. Transfer must be completed through a licensed FFL dealer. FX-19 pistols cannot be shipped to CA, CT, DC, HI, IL, MD, MA, NJ, or NY. Must ship overnight. Verify local regulations — including magazine capacity limits — before ordering.

Frequently Asked Questions
Is the Faxon FX-19X Hellfire a complete, ready-to-shoot pistol?
Yes. The FX-19X-HF-02 is a complete, serialized semi-automatic pistol. It ships with every component needed to fire, including two 17-round magazines, a removable RMR cover plate, a 1/2x28 thread protector pre-installed on the barrel, a federally-required trigger lock, and the operator's manual. You will need to purchase 9mm Luger ammunition separately. All firearm purchases require transfer through a licensed FFL dealer.
What's the frame and slide configuration on the FX-19X Hellfire?
The FX-19X Hellfire pairs a full-size FX-19X Gen 2 frame with a compact Hellfire slide — the same general configuration as a Glock® 19X or Glock® 45. This gives you a full hand grip, 17+1 capacity from standard Glock® 17 magazines, and improved recoil control, paired with a fast-handling compact slide.
For compatibility:
- Holsters: Glock® 19X / Glock® 45-style holsters fit best (full-size frame, compact slide). Many G17 holsters also work, with extra empty space at the muzzle.
- Magazines: Standard Glock® 17 magazines (10, 15, 17, 24, and 33-round where legal). G19/G26 magazines will function but leave a gap below the frame.
- Frame parts: Glock® 17 Gen 3 grip accessories, slide stops, magazine releases, and trigger guard parts.
- Slide parts: Glock® 19 Gen 3 slide aftermarket parts (extractors, firing pins, etc.).
Note: Glock® Gen 4 / Gen 5 specific parts are not guaranteed to fit due to different frame rail and grip module geometry. The FX-19X Gen 2 frame matches Gen 3 dimensions specifically.
What's the difference between the FX-19 and FX-19X variants?
All FX-19 Gen 2 pistols share the same compact slide platform and Glock® 19 Gen 3 slide compatibility. The differences are in the frame (compact vs. full-size) and barrel/slide trim level:
- FX-19 Duty (FX-19-D-02) — Compact frame, Duty slide, Faxon Duty Series non-threaded barrel. 10+1 capacity. $850 MSRP. Most accessible price point.
- FX-19 Patriot Gen 2 (FX-19-P-02) — Compact frame, Patriot slide, Match Series non-threaded barrel. 10+1 capacity. $999 MSRP.
- FX-19 Hellfire Gen 2 (FX-19-HF-02) — Compact frame, Hellfire slide, Match Series threaded barrel. 10+1 capacity. $1,050 MSRP.
- FX-19X Patriot (FX-19X-P-02) — Full-size frame, compact Patriot slide, Match Series non-threaded barrel. 17+1 capacity.
- FX-19X Hellfire (FX-19X-HF-02) — This pistol. Full-size frame, compact Hellfire slide, Match Series flame-fluted threaded barrel. 17+1 capacity. $1,075 MSRP. Flagship build.
Can I run a suppressor or compensator on the FX-19X Hellfire?
Yes — the FX-19X Hellfire ships with a 1/2x28 threaded Match Series barrel, the standard thread pitch for 9mm pistols. It's a direct host for most 9mm suppressors and the full Faxon EXOS® pistol compensator line out of the box — no muzzle device swap or thread adapter required.
The barrel ships with a 1/2x28 thread protector pre-installed. Remove the protector to mount your suppressor or compensator. Important: when running a suppressor on a Glock-pattern pistol, the optic and slide-stop spring may require tuning — review our Shooting Suppressed guide before your first range trip.
What optic mounts on the FX-19X Hellfire?
The Hellfire slide is factory-cut for the Trijicon RMR® footprint, which is one of the most widely supported optic patterns on the market. Compatible optics include the Trijicon RMR / RMRcc, Holosun 507C / 508T / 407C, and any other red dot using the standard RMR footprint.
The slide ships with a removable cover plate installed — just remove the cover plate screws, lift it off, and install your optic. Use the Night Fision® Optics-Ready Stealth Series rear sight for lower 1/3 co-witness with any RMR-footprint optic.
Important: Some mounting screws supplied with RMR-footprint optics may be too long and impinge on the extractor spring rod. Verify the extractor moves freely after installing your optic and use shorter screws or a thin shim if needed.
What barrel does the FX-19X Hellfire use, and how is it different from the Duty Series barrel?
The FX-19X Hellfire ships with the Faxon Match Series Flame-Fluted Threaded Barrel for G19 Gen 2-5 9mm in 1/2x28 threaded configuration — the same Match Series barrel we sell as a drop-in upgrade for stock Glock® 19 Gen 3 pistols. It's machined in-house in Cincinnati, Ohio from 416-R stainless steel (the premium match-grade stainless used in high-end precision rifle barrels) and finished with a durable QPQ nitride treatment inside and out for additional hardness, wear resistance, and long service life.
Compared to our Duty Series barrel (used in the FX-19 Duty), the Match Series adds tighter tolerances for improved accuracy and flame fluting for weight reduction and improved heat dissipation. Compared to a factory polygonal-rifled Glock® barrel, the Faxon Match Series barrel uses conventional rifling, which is generally regarded as more forgiving with lead and reloaded ammunition.
What magazines does the FX-19X Hellfire accept?
The FX-19X Hellfire is built on the full-size FX-19X Gen 2 frame, which accepts standard Glock® 17 magazines — including 10-round, 15-round, 17-round (standard), and extended 24/33-round magazines where legal. The pistol ships with two 17-round magazines.
Smaller Glock® 19 / 26 / 43 / 43X / 48 magazines will not fit properly — the frame is full-size G17 pattern, not compact G19 pattern. If you're running magazines from your existing Glock® 17, they will work as-is.
Where can the FX-19X Hellfire be shipped?
FX-19 pistols cannot be shipped to CA, CT, DC, HI, IL, MD, MA, NJ, or NY. Shipments must go overnight to a licensed FFL dealer in your state. Verify your state and local handgun and magazine capacity regulations before ordering — some jurisdictions restrict 17-round magazines. Faxon Firearms is not responsible for compliance with local handgun ordinances at the buyer's location.
