Fusion Firearms XP Pro 9mm 4in 17rd Optic-Ready Black
About this product
What is the Fusion Firearms XP Pro 9mm 4in 17rd Optic-Ready Black? It's a duty-caliber, 1911-pattern double-stack pistol built to accept Glock 17 magazines and modern optics for immediate use as a competition-ready or defensive sidearm. This pistol re-interprets John Browning's design with a 17+1 capacity 9mm chambering, a 4-inch barrel for balanced velocity, and a tri-topped slide cut for a red-dot sight without sacrificing traditional sight-co-witnessing capability. It's built from CNC-machined bar-stock components where durability matters most, and it ships ready for the range with two magazines and an RMR adapter plate.
What is the Fusion Firearms XP Pro used for?
This pistol is built for shooters who demand a modernized 1911 platform that functions as both a high-capacity competition gun and a serious-duty defensive firearm. Its direct 1911-style trigger and grip angle appeal to traditionalists moving up to a 17-round capacity, while its optic-ready slide and Glock-compatible magazines address the practical needs of modern competitive shooting and tactical training. The 37.5-ounce unloaded weight dampens 9mm recoil for faster splits, and the full-length guide rod system provides consistent lockup shot after shot.
How does the Fusion Firearms XP Pro compare to a standard 1911 like the Colt Government?
The Fusion XP Pro holds over double the ammunition of a standard Colt Government Model 1911 while maintaining an identical manual of arms and external safety configuration. Where the Colt Government delivers 8+1 rounds of .45 ACP from proprietary magazines, the Fusion XP Pro feeds 17+1 rounds of 9mm from ubiquitous Glock 17 magazines, providing a direct advantage in round count and magazine availability. For mechanical precision in a controlled-feed action, the single-stack Colt retains an edge, but for high-volume shooting where spare magazine cost and availability are critical, the Fusion XP Pro is the superior logistical choice.
What does the Fusion Firearms XP Pro weigh and what are its dimensions?
The pistol has an unloaded weight of 37.5 ounces (1063 grams) and an overall length of 7.75 inches (197 mm) with its 4-inch (102 mm) barrel. The frame width measures 1.25 inches (32 mm) at its widest point, which is 0.2 inches wider than a traditional single-stack 1911 to accommodate the double-stack magazine well. This dimensional increase creates a slightly fuller grip while maintaining the classic 1911 grip angle and trigger reach for natural point-of-aim alignment with minimal retraining.
Who is this pistol NOT for?
The Fusion XP Pro is a poor choice for concealed carry permit holders seeking a slim, subcompact firearm for deep concealment. Its 1.25-inch frame width and 7.75-inch overall length make it significantly bulkier than dedicated concealment pistols like the SIG P365, which measures just 1 inch wide and 5.8 inches long. If your primary need is a lightweight, short-barreled firearm for discreet everyday carry, consider our line of more compact offerings like the Stevens 334 Rifle for a different application entirely.
What's included in the box with the Fusion Firearms XP Pro?
Ironclad Armory ships this pistol with two 17-round Glock-compatible steel magazines, one RMR-pattern optic mounting plate, a polymer chamber flag, and a basic hard-sided lockable case. The factory does not include a cleaning kit, extra grip panels, or additional optic adapter plates for Holosun or Leupold DeltaPoint Pro footprints—those are sold separately. The rear sight plate, once removed to install an optic, is a small component you must store securely to maintain co-witness capability with your backup iron sights.
Is the Fusion Firearms XP Pro worth $1049.99?
At this price point, you are paying for a factory-built, optic-ready 1911-pattern pistol with a double-stack magazine system that bypasses the typical $200-300 custom gunsmithing fee for such a conversion. The value lies in its immediate usability with common Glock 17 magazines and modern red-dot sights without additional machining. Compared to buying a base-model 1911 and having it custom-worked, the Fusion XP Pro saves you approximately 6-8 weeks of gunsmith lead time and arrives as a complete, tested system. For shooters wanting to step into competitive USPSA Limited Optics or modern tactical pistol courses without a custom build queue, the price is justified.

Pros & cons
What works
- Accepts Glock 17 magazines — uses a $25 OEM part instead of $70+ proprietary mags
- Optic-ready slide ships with RMR plate — saves $150-250 in milling costs and 4-6 week lead time
- Weighs 37.5 oz unloaded — 8 oz heavier than a polymer striker-fired gun for reduced felt recoil
- Tennifer QPQ finish provides 72-hour salt spray corrosion resistance per MIL-STD testing
Trade-offs
- No front strap checkering — requires a $120-180 stippling or grip tape job for secure handling
- Rear sight plate is a tiny, easy-to-lose component — store it immediately after optic installation
- Slide stop lever is stiff from factory — requires 300-500 rounds or manual polishing to break in smoothly
- Frame is 0.2" wider than standard 1911 — incompatible with most existing 1911 holsters without modification

Frequently asked questions
- Is the optic cut compatible with Holosun 507C red dots?
- No, the factory-provided mounting plate is specifically machined for the Trijicon RMR footprint. To mount a Holosun 507C, which uses the same pattern, you will need to verify the specific screw length and head style, as Holosun often uses different hardware than Trijicon. Most installations require sourcing 6-32 thread screws between 0.30 and 0.40 inches in length from a supplier like McMaster-Carr.
- Does it fit standard 1911 holsters?
- It will not fit most standard 1911 holsters due to its wider 1.25-inch frame and squared trigger guard geometry. You need a holster specifically molded for the Fusion Firearms double-stack 1911 pattern or a universal kydex holster heated and re-molded. Expect a 3-5 week lead time for a custom-made holster from companies like Tier 1 Concealed or Black Rhino Concealment.
- How long does shipping take to an FFL?
- Ironclad Armory processes and ships orders within 2-3 business days after FFL verification is received. Transit time via UPS Ground is typically 5-7 business days to most continental US locations. The total timeline from order to FLL arrival is usually 7-10 business days, not including the transfer processing time at your selected dealer.
- Can I return it if it doesn't cycle my ammunition?
- We do not accept returns due to ammunition compatibility issues unless a mechanical defect is verified by our armorer. The pistol is rated for SAAMI-spec 9mm Luger ammunition from 115gr to 147gr. If you experience failures with 500 rounds of standard-pressure FMJ from brands like Federal, Winchester, or Blazer, contact our support team to initiate a 7-10 day inspection and repair process.
- Does this work with Glock 19 magazines?
- Yes, the magazine well accepts any Glock-pattern double-stack 9mm magazine, including 15-round Glock 19 magazines. The shorter magazines will sit flush and function reliably but leave a 0.8-inch gap at the base of the grip. For carry purposes, this can be an advantage, but for competition, you sacrifice two rounds of capacity compared to the included 17-round magazines.
