Grand Power X-Calibur: An In-Depth Review
Originally published in November 2021, this article now features updated insights into the Grand Power X-Calibur, a unique contender in the handgun market.
Introduction to the Grand Power X-Calibur
As Clint Smith famously stated, “The only purpose for a pistol is to fight your way back to the rifle you should have never laid down.” This sentiment resonates particularly in regions where handguns are the only legally permissible option for daily carry. The Grand Power X-Calibur epitomizes an attempt to bridge the gap between a compact firearm and the functionality typically associated with carbines.
Specifications and Design
Caliber Variants
The X-Calibur is available in both 9mm and .22 caliber, catering to different shooting preferences. Its design emphasizes accuracy, with a 5-inch heavy fluted barrel that enhances sight radius, making it effective at distances up to 60 yards without support, and even 100 yards when supported.
Sights and Ergonomics
Equipped with a fiber-optic front sight paired with a textured black rear sight, the X-Calibur is optimized for daylight use. However, for low-light conditions, it can accommodate Hi-Viz H3 sights with tritium illumination. The ergonomics are further enhanced by adjustable ambidextrous safety levers and grip inserts, allowing users to tailor the handgun to their preferences.

Innovative Rotary Breech Mechanism
A standout feature of the X-Calibur is its rotary breech design, a noteworthy advancement in handgun technology. This design enables smoother operation and reduced recoil, lending itself to increased control during rapid firing. The unique mechanism minimizes felt recoil compared to traditional semi-auto pistols, allowing for quicker follow-up shots.
Performance and Handling
The felt recoil of the X-Calibur resembles that of a .22 Magnum, which is quite mild for a centerfire pistol. This facilitates extended practice sessions and quick return to target, a critical factor in self-defense scenarios. The longer linear travel before unlocking the breech reduces noise and keeps the action cleaner compared to tilt-barrel systems.
Magazine and Ammunition
The X-Calibur supports 16+1 metal magazines capable of handling diverse ammunition types efficiently. My preference leans towards Seismic 185gr hollow points due to their subsonic nature, offering reduced flash and noise without sacrificing performance. Ballistic tests highlight respectable penetration and expansion, indicative of reliable stopping power.

Availability and Accessories
While rotary breech firearms like the X-Calibur aren’t widespread in the U.S., they still have a supportive community. Companies like Falco produce leather and Kydex holsters tailored for the X-Calibur. Additionally, Global Ordnance provides magazines and accessories at competitive prices, ensuring that this firearm remains practical for everyday use.
Conclusion
My experience with the Grand Power X-Calibur stems from competitive shooting, where its surprising accuracy and reliability set it apart from other handguns. Combining features from classic models like the M1911 and Glock, the X-Calibur presents a formidable option for shooters seeking both performance and comfort in a handgun.
For those who value innovation coupled with proven principles in firearm design, the X-Calibur is a noteworthy choice. Its combination of precision, ergonomics, and effective recoil management positions it well for both sport and self-defense applications.
