Glock 23 V MOS owners who shoot .40 S&W tend to appreciate the V-series updates: the flared mag well and removal of finger grooves make reloads faster and the grip more adaptable to different hand sizes. The Marksman barrel draws consistent positive comments for accuracy at the range.

The MOS cut is a practical inclusion. Owners who wanted to mount a red dot without gunsmithing work find it straightforward, though they note that adapter plates can add noticeable height to the optic. A smaller group of buyers would have preferred fixed sights with a tighter profile.

The .40 S&W chambering splits the community. Shooters who prefer the cartridge for duty or competition load out happily; others feel 9mm would give them more capacity and softer recoil in the same platform. Shipping with 3 magazines is broadly seen as a plus.
