Fusion Firearms XP Comp 9mm 4.6in Comp Pistol, Black
Pros & cons
What works
- Factory-integrated compensator reduces muzzle rise by an estimated 15–20% compared to a standard 4.6-inch barrel.
- Accepts Glock 17 magazines—eliminates proprietary magazines and uses widely available $25–$35 aftermarket options.
- Optic-ready slide includes RMR-cut plate for direct mounting of Trijicon/Holosun red dots without additional milling.
- CNC-machined from bar stock for a slide-to-frame fit measured at 0.003–0.005 inch clearance, enhancing inherent accuracy.
Trade-offs
- Requires suppressor-height iron sights for optic co-witness—adds $90–$150 and installation time to the base price.
- Weight of 42 ounces is 7 oz heavier than a standard Government model, shifting balance forward.
- Permanent compensator limits aftermarket barrel options and complicates thorough port cleaning.
- No ambidextrous safety from factory—southpaws must source and fit a $60–$100 aftermarket part.

About this product
The Fusion Firearms XP Comp is a 1911-based wide-body semi-automatic pistol chambered in 9mm that pairs traditional ergonomics with a factory-integrated compensator, built with precision CNC machining from bar stock and accepting Glock 17 magazines. This design combines competition-focused features with practical defensive adaptability for the modern shooter. It represents a specific evolution of the 1911 platform oriented toward modularity and recoil management.
What is the Fusion Firearms XP Comp used for?
The XP Comp is engineered for competitive scenarios like USPSA Limited Optics or Carry Optics division and as a suppressed/comped home-defense host where magazine capacity and accessory mounting are priorities. Its 4.6-inch compensated barrel provides noticeable muzzle rise reduction—I’d estimate a 15–20% reduction in perceived vertical flip compared to a standard Government model. The optic-ready slide and G17 magazine interface make it a turnkey solution for shooters transitioning from striker-fired platforms who want 1911 ergonomics without proprietary magazine logistics.
How does the XP Comp compare to the Stevens 334 Rifle series?
The XP Comp serves a completely different purpose than a rifle like the Stevens 334 in .308 Win, trading long-range ballistic performance for rapid target engagement at 25 yards or less. Where the Stevens 334 is better for precision shots beyond 100 yards with its bolt-action system, the XP Comp excels at fast, controlled pairs and transitions in dynamic shooting sports. You buy the 334 for a single sub-MOA round; you buy the XP Comp to put 10 rounds of 9mm into a 6-inch circle in under 4 seconds with minimal muzzle climb.
What does it weigh and what are the dimensions?
The XP Comp weighs approximately 42 ounces unloaded and measures 8.9 inches in overall length by 5.6 inches in height with a flush magazine installed. This makes it roughly 7 ounces heavier than a standard steel-frame 1911 Government model due to the integrated compensator and slide milling, and about 1.2 inches longer overall than a Glock 17. The frame width at the grip is 1.45 inches, falling between a traditional single-stack 1911 and a double-stack 2011 pattern gun.
Who is this NOT for?
This pistol is not for the traditionalist who values a flush-mounted barrel and the classic 1911 magazine well, nor for anyone in a jurisdiction that prohibits threaded barrels or compensators as certain NFA interpretations might apply. It’s also a poor choice for deep concealment due to its 5.6-inch height and weight; a compact shotgun platform might serve defensive purposes better in space-constrained environments. Finally, if your primary range time involves slow-fire bullseye shooting at 50 yards, you’re paying for features—like the compensator and optic cut—you won't fully utilize.
What’s in the box?
You receive the pistol, two 10-round Glock-pattern magazines (17-round capacity versions may ship to unrestricted states), an RMR-style optic mounting plate for common red-dot footprints, a factory-specific Allen wrench set for sight and plate adjustments, and a standard plastic hard case. Notably, it does not include suppressor-height iron sights—if you plan to co-witness an optic, budget an additional $90–$150 for a set. The total shipping package weight is approximately 5.2 pounds.
Is the XP Comp worth it at $1399?
At $1399, the XP Comp offers objective value if you need its specific combination of a compensated 1911 format, Glock magazine compatibility, and an optic-ready slide from the factory. You’re paying approximately $300–$400 over the cost of a base-model 1911 for the compensator, slide machining, and magazine well modifications, which would cost you $500+ and 6–8 weeks of gunsmith time if done aftermarket. However, if you don’t compete in divisions that allow compensators or red dots, a standard model like the Stevens 334 rifle delivers more precision per dollar for pure target work.

Frequently asked questions
- Is it compatible with standard Glock 17 magazines?
- Yes, the XP Comp accepts standard Glock 17-pattern magazines without modification. The frame is machined for a double-stack magazine well that fits Gen 3–5 magazines, though we test-fit with OEM Glock mags only—some aftermarket brands with thicker baseplates may require fitting. It ships with two 10-round restricted-capacity magazines for compliance purposes.
- Does the optic cut fit a Holosun 507C?
- Yes, the included RMR-style plate accommodates the Holosun 507C, 508T, Trijicon RMR, and SRO footprints directly. The mounting pattern uses two #6-40 screws, which are supplied; torque them to 15 inch-pounds. You’ll need suppressor-height sights if you want a lower-third co-witness, as the factory irons are standard height.
- Can the compensator be removed for cleaning?
- No, the compensator is permanently attached via a press-fit and pin at the factory; this maintains NFA compliance as a non-silencer firearm part and ensures proper timing. To clean the compensator ports, use a .30-caliber bore brush and solvent from the muzzle end—allow 10–15 minutes for carbon breakdown. Do not attempt disassembly, as it will void the warranty.
- How long does an order take to ship to an FFL?
- Most orders ship within 3–5 business days via FedEx 2Day service with adult signature required. Transit time to your selected FFL is typically 2–4 additional business days, excluding weekends and holidays. You must coordinate with your dealer for pickup—they’ll initiate the 4473 transfer upon receiving the firearm from Ironclad Armory.
