I have a John Wick Glock 34 Combat Master. Yes, with the cost of the modification and the gun, it was around $2400. I wanted it because I wanted it. I did not expect to get the performance out of it that Taran claims online... But, I still wanted it....
I have previously posted a review here before. It really is awesome. I was damn impressed. The 5th Gen Glock marksman barrels seem to be more accurate. Combined with the trigger work and the other work Taran Tactical does - it is amazingly accurate. I have owned 3 high end 1911s in the past (and twelve 1911s total). I shoot this gun as well as those guns. And, with my neck and shoulder issues, I like the lighter weight of the Glock.
I had planned to get a Brown 9mm 1911 one day - I have previously owned 2 Ed Browns and loved them. Now, I decided not to bother. In fact, I sent a Glock 19 to Taran Tactical 1 month after getting this JW Glock. Now, have another 14+ month wait, but they do awesome work.
Kinda like you won't "get it," until you own a high end 1911, you won't get a high end Glock until you try one. And, there are so many flavors (different companies) - so, it can depend on who ya go with.
