Owners who move to the G23 V MOS from older Glock compact variants typically lead with the V Series grip changes. Removing the finger grooves and adding the flared mag well gives the pistol a cleaner feel in the hand, and shooters with smaller or larger hands often find it easier to grip consistently than earlier generations.

The MOS cut is the other main draw. Mounting a red dot directly to the slide without adapter plates means a lower optic height, and owners running the G23 V as a duty or range gun appreciate that the system holds zero through sustained shooting. The .40 S&W chambering brings more felt recoil than a comparable 9mm compact, which some owners find manageable and others mention as a drawback for high-volume practice.

Value perception is split. At its price point, the G23 V MOS competes with red-dot-ready compacts from several other manufacturers, and buyers who want a proven platform accept the premium. Critics note that the 10-round capacity in a compact .40 leaves less room for error than higher-capacity alternatives.
