Key Features
- Match-Grade Trigger with Short Reset – Why it matters: Delivers a crisp, 4-lb break and minimal overtravel, helping you stack shots on target without pulling the next one off.
- Optic-Ready Slide with Lightening Cuts – Why it matters: Accepts MRSc-pattern red dots for faster target acquisition, while the serrations and cuts reduce reciprocating mass for quicker follow-ups.
- Fiber Optic Front Sight – Why it matters: Provides a bright, high-contrast front sight picture in any lighting, so you can pick up the front blade instantly on the draw.
- Enhanced Textured Grip with All-Steel Dust Cover – Why it matters: The aggressive texture locks your hand in place under recoil, and the steel dust cover adds weight forward to reduce muzzle flip.
- 15+1 Capacity with Ambidextrous Controls – Why it matters: Gives you a competitive magazine capacity for USPSA Carry Optics or IDPA SSP, and the ambi safety makes it southpaw-friendly out of the box.
Who It’s For
This pistol is built for the competitive shooter who demands a flat-shooting, optic-ready platform right from the factory. If you compete in USPSA Carry Optics or IDPA SSP, or you’re a serious range shooter who wants match accuracy without a custom build, the X-Calibur Match CO Mk23 fits the bill. It also suits the shooter who prefers a heavy, stable frame to tame 9mm recoil for tight splits.
Pros / Cons
- Pros: Excellent trigger out of the box; optic-ready without adapter plates; steel dust cover adds muzzle stability; ambi controls for left-handed shooters.
- Cons: Holster availability is limited compared to Glock or SIG patterns; the 4.80-inch barrel may not fit some 5-inch-only competition divisions.

FAQ
What footprint optic does the Grand Power X-Calibur Match CO Mk23 use?
The slide is cut for the RMSc footprint, which includes popular optics like the Holosun 407K/507K and SIG Romeo Zero. You may need an adapter plate for other footprints.
Is this pistol compatible with standard Grand Power holsters?
Due to the steel dust cover and optic cut, the X-Calibur Match CO Mk23 requires holsters designed specifically for the X-Calibur series. Standard GP holsters may not fit the wider slide profile.
Can I use this pistol in USPSA Carry Optics division?
Yes. The 4.80-inch barrel falls within the 5-inch limit, and the 15+1 capacity is legal for Carry Optics. The optic-ready slide makes it a strong contender right out of the box.
What is the trigger pull weight from the factory?
Per Grand Power specs, the trigger breaks at approximately 4 pounds with a short reset. This is a match-grade trigger intended for competition use.
