Description
Grand Power is a Slovakian manufacturer that has quietly built a devoted following among competition and precision-focused pistol shooters, and the X-Calibur is their flagship. The MK23 generation represents a significant refinement of the platform, and the MATCH CO variant takes things a step further with features specifically aimed at getting the most out of every shot.
The headline feature of the X-Calibur line is Grand Power's patented rotating barrel action. Instead of the conventional Browning-style tilting barrel that every other service pistol on the market uses, the barrel rotates during the firing cycle to unlock from the slide. The result is a straight-rearward recoil impulse with no barrel movement off the axis of the bore, which translates to a noticeably smoother, flatter-shooting feel that plenty of experienced shooters have compared to firing a heavier all-metal pistol. That smoothness makes fast, accurate follow-up shots significantly easier to manage.
What separates the MATCH variant from the standard X-Calibur CO is the all-steel dust cover. It extends from Grand Power's billet stainless internal chassis and adds meaningful non-reciprocating weight to the front of the gun, further taming muzzle rise during rapid strings of fire. The slide is aggressively lightening-cut and serrated, with a dedicated optic cut machined in. From the factory you get a red fiber optic front sight paired with a fully adjustable rear, plus four optic mounting plates covering Vortex/Docter Noblex, Trijicon RMR, CMORE STS2, and Shield SMS footprints. Whether you want to run irons or mount a dot, you are covered without ordering anything extra.
The trigger is SA/DA with a crisp single-action break that reviewers consistently praise for its predictability and short reset. Controls are fully ambidextrous, including the slide stop, mag release, and manual safety. The grip ships with interchangeable backstraps so you can dial in the fit for your hand size. The frame is built around a CNC-machined steel chassis, so there are no MIM parts in the critical areas of the gun.
This pistol ships with three 15-round magazines, a hard case, four optic mounting plates, interchangeable grip backstraps, and a spare recoil spring. It is purpose-built for sport and competition shooting, but it earns its keep just as well as a range gun for anyone who wants a high-quality, deeply satisfying pistol to shoot.

Frequently Asked Questions
What makes the Grand Power X-Calibur Match CO MK23 different from a standard X-Calibur CO?
The MATCH variant adds an all-steel dust cover that extends from the pistol's billet stainless internal chassis. This adds non-reciprocating weight to the front of the gun, which reduces muzzle flip and improves control during rapid fire. The MATCH CO also comes optic-ready with four mounting plates included, whereas the standard CO may ship with fewer mounting options depending on the variant.
How does the rotating barrel action work and why does it matter?
Instead of a conventional tilting-barrel Browning-style lockup, the X-Calibur's barrel rotates roughly 45 degrees during the firing cycle to unlock from the slide. This keeps the barrel's movement in line with the bore axis rather than dropping away, which produces a straighter-back recoil impulse and a noticeably smoother shooting feel. Many shooters describe it as shooting flatter than other polymer-frame 9mm pistols, which helps with faster sight recovery between shots.
Which red dot sights are compatible with the MK23 X-Calibur Match CO?
The pistol ships with four optic mounting plates covering the most popular footprints in use today: Vortex/Docter Noblex, Trijicon RMR, CMORE STS2, and Shield SMS. That covers a wide range of popular red dots without needing an aftermarket adapter. The fiber optic iron sights are still fully usable if you prefer to shoot without an optic.
Is the X-Calibur Match CO MK23 a good fit for competitive shooting like USPSA or IPSC?
The X-Calibur line was purpose-designed for sport and practical shooting competition. The crisp SA/DA trigger, short reset, fully ambidextrous controls, and optic-ready slide all check the boxes for Production or Limited division use. The MATCH variant's steel dust cover adds extra muzzle control that makes a real difference during timed strings of rapid fire.
What is the trigger like on the X-Calibur Match CO MK23?
The single-action trigger is widely praised for its light, crisp break with a short reset, making it one of the standout features of the platform. The pistol also functions in double-action, which allows for a second-strike capability if a round fails to fire. The DA pull is heavier, as expected, but the SA mode is where this trigger really shines for accurate, fast shooting.
How many magazines come with the Grand Power X-Calibur Match CO MK23?
The pistol ships from the factory with three 15-round magazines, a spare recoil spring, four optic mounting plates, and interchangeable grip backstraps, all in a hard carry case. This is a notably complete package right out of the box compared to most pistols that ship with only one or two magazines.
