Owners of the Grand Power P1S MK23 point to the four included optic adapter plates as a practical differentiator. Most find the compact size comfortable for carry while still fitting the optics-ready setup they want on a duty-style pistol.

The rotating barrel mechanism Grand Power uses gets attention from owners who appreciate the recoil profile it produces. Some shooters find the controls take a break-in period to become intuitive, particularly if they are coming from other compact platforms.

Magazine availability outside the three included is a recurring concern for P1S owners, since Grand Power is less widely distributed than mainstream brands. Build quality comments are generally positive, though the brand's limited aftermarket is a noted drawback.
