Owners of the Grand Power K100 Mk23 tend to highlight the DA/SA trigger as a standout element; the long, smooth first pull transitions cleanly to a shorter reset in SA mode, which takes some dry-fire time to master but rewards consistent practice. The bundled four optic adapter plates are a practical touch that owners appreciate, letting them mount a variety of red dots without hunting for aftermarket hardware.

In the hand, the K100 Mk23 draws comparisons to the CZ 75 family in terms of grip angle and slide-inside-frame feel. Most owners find it comfortable for extended range sessions. The matte black finish holds up well to normal range wear, though some report the slide serrations are shallower than they prefer.

Value perception is generally positive given the optics-ready setup and three-magazine bundle included at purchase. The trigger divides opinion: experienced DA/SA shooters embrace it, while those coming from striker-fired guns find the adjustment curve steeper than expected.
