Owners of the Grand Power Q1S MK23 appreciate its rotating barrel design, which is a defining characteristic of the Q1 platform and contributes to smooth recoil. The compact dimensions make it manageable for carry, and the 3.66-inch barrel sits in a practical length for a carry-sized pistol.

The Q1S MK23 draws comparisons to other European compact handguns, and owners generally report good reliability out of the box. Ergonomics get favorable mentions, though the grip angle and controls can feel unfamiliar to shooters coming from more common American platforms. The trigger earns measured praise, often described as acceptable rather than exceptional.

Aftermarket support for Grand Power pistols is limited compared to mainstream brands, which is the most common owner complaint. Finding holsters specifically fit to the Q1S MK23 takes extra effort, and magazine availability outside the included ones can be inconsistent depending on region.
