Very happy with it on initial impressions. I have a Gen 5 G19 MOS that is probably the best pistol Glock has produced in terms of function, fit, and overall usefulness as a carry gun. The G23 is exactly the same pistol as far as the frame; same great trigger, same great ergonomics and feel. The difference is in the slide. The Gen 5 G23 slide is 3mm thicker than the G19 and the Gen 4 G23. This worried me since the G19 is already a monster when compared to my P365. Hold the G19 and G23 side by side and the difference is obvious. But when you are just handling the G23, you don't really notice it. It's not nearly as bad as the photos suggest. Trigger was a little better than my G19 with a pull of 5lbs and very crisp and predictable with a lovely re-set. No time to take it to the range, and working a 12-hr shift tomorrow, so won't get to try it out until next week. I've already worked up some loads for it using 200 grain Speer Gold Dots and 180 grain RMRs and they plunked fine at the recommended 1.125" OAL. Can't wait to do some bench rest shooting to see what it's capable of, as well as some speed drills. Don't have a Gen 4 G23 to compare it to in terms of recoil or accuracy. But I do have a Gen 4 G35 match gun that will do 1.5" groups at 25 yards. Hoping the new Gen 5 can match it.
