I know the ka-boom question tends to get testy, and I have no real dog in the fight as I have no .40, but whenever the question of KBs comes up nobody ever seems to approach it the right way IMO.
To know whether G23s KB more than other guns you have to know not only how many Kbs there have been but how many G23s vs anything else are in use, and how often they are fired.
Without that information you have the same situation as saying "I see more Toyotas broken down than I do Maseratis therefore Toyotas are more likely to break down". If you don't know the number of Toyotas on the road and the amount of miles they drive, and the same for Maseratis, that may seem like a safe bet, at least on an inferential and anecdotal level.
Of course because we all know, at least in general, the vastly greater number and miles driven for the utilitarian midprice Toyota vs. the exotic adult toy Maserati, we all intuitively know Toyotas are in fact more reliable.
Now I don't claim that Glocks are in that kind of relative position - the extreme example is there to make the point clear. However AFAIK Glocks do outsell other brands, especially in the 40 caliber which has a strong LEO following where Glocks definitely dominate. I have no idea on rounds fired except to assume that midprice guns known for durability are more likely to be blasted away for 500-rd range sessions.
So how often AS A RATE do Glock .40 caliber models KB compared to others? I dunno - and unless someone has the data above, they probably don't either.
BTW Congrats on the new gun. I have found Glocks in general to be enjoyable, low maintenance and reliable guns with nary a failure in my own experience, and more accurate than they are reputed to be too. I personally have no inclination towards the caliber so can't say anything about the G23 per se, but I would be surprised if it did not perform the same.
