At least it doesn't have those gawdawful forward slide serrations but what's worse is that the gun is that butt-ugly Coyote Turd Yellow color and has that funny little "lip" in front of the magazine.
I did get to shoot a G19x, though, and I really liked how the long grip.short barrel points more naturally and balances in your hand. I generally much prefer a G19 (or G23) to a G17 or G22, but I can shoot a G45 better than either one because of the better balance and greater pointability.
I've shot G17's with chopped G19 length grips which are theoretically supposed to be the ideal configuration but in actual practice they feel awkward and clumsy in your hand. and the 1/2 inch longer slide offers at most a 25 fps advantage in velocity and most guns, when you actually chronograph them will differ by more than that, even if it's the same length barrel in the same brand gun. I've chronographed a lot of guns and that's true of both rifles and pistols. And as far as sight radius, a lot of people shoot a G26
better than they can shoot a G19
