Looks like Glock capitalized on the Glock 19x marketing strategy. Release a model folks want in a color only some like but others will buy because they like the gun.
Then release it in the preferred black and watch a bunch of them buy it again, plus all those waiting for the black version.
Brilliant.
I like the Black better myself, never much liked the 2 tone look on any guns. I also like a 26 or 19 better and doubt I'd have gotten one regardless, though they do feel pretty good in the hand.
