Key Features
- Double-Stack 1911 Frame with Glock 17 Magazine Compatibility — Why it matters: You get the familiar 1911 grip angle and trigger feel while running widely available, affordable Glock magazines for 17+1 rounds in 9mm.
- Optic-Ready Slide with RMR Plate — Why it matters: No gunsmith fitting needed. The tri-topped slide includes a pre-milled RMR footprint and a mounting plate, so you can mount a red dot in minutes.
- One-Piece Steel Milled Trigger — Why it matters: Machined from a single piece of bar stock, this trigger gives you a crisp, repeatable break with zero creep—typical of a custom 1911 trigger pull.
- Pro Cocking Serrations and Front Vent Cuts — Why it matters: The aggressive serrations give you positive purchase on the slide even with sweaty hands, and the front vents reduce muzzle flip for faster follow-up shots.
- Tennifer QPQ Finish — Why it matters: This salt-bath nitrocarburizing process penetrates the steel surface, providing extreme corrosion resistance and a low-glare black that won’t wear off like cerakote.
Who It’s For
The Fusion Firearms XP Pro is built for shooters who want the 1911 platform’s trigger and ergonomics but need double-stack capacity for duty, competition, or home defense. It fits experienced 1911 fans who refuse to give up the grip safety and thumb safety, as well as Glock owners looking for a more refined shooting experience without buying new magazines.
Pros / Cons
- Pro: Accepts Glock 17 mags — no proprietary magazines to hunt for.
- Pro: CNC-machined bar-stock components where specified, not MIM parts.
- Pro: Ships with an RMR mounting plate included in the box.

FAQ
Does the Fusion Firearms XP Pro come with a magazine?
Yes, it ships with one 17-round Glock 17 magazine. Additional Glock 17 magazines are widely available from any gun shop or online retailer.
Is the slide cut for other optics besides RMR?
The slide is cut specifically for the RMR footprint. It includes an RMR mounting plate. For other optics, you may need an adapter plate or aftermarket milling.
What holsters fit the Fusion Firearms XP Pro?
Because of the 1911-style frame and Glock magazine well, the XP Pro fits most 1911 double-stack holsters (e.g., Safariland 6360 ALS for 1911 5-inch with light). Always verify holster fit with your specific setup.
Can I use standard 1911 triggers in this pistol?
No. The XP Pro uses a proprietary one-piece steel milled trigger designed specifically for this frame. Aftermarket 1911 triggers are not compatible.
Is the grip safety adjustable or removable?
The grip safety is fixed and non-adjustable. It is integral to the frame design and cannot be removed without modifying the frame. Some shooters find it requires a high grip to disengage fully.
Why Buy the Fusion Firearms XP Pro
According to Fusion Firearms specs, the XP Pro is machined from bar-stock steel and uses a one-piece steel trigger—a rarity at this price point. The double-stack frame holds 17 rounds of 9mm, and the Tennifer QPQ finish outlasts standard bluing by a wide margin. If you want a 1911 that runs Glock mags and accepts a red dot without a gunsmith, this is your pistol.
