So I'm interested in a Glock. I know there is the 17 and the 19 as the two most popular and reliable 9 mm out there. But also doing some research I know they have the Glock 19 X which is sort of a combination of the 19 and the 17. I personally wish it was kind of backwards with the 17 slide on the 19 frame, if that makes sense. But for those who owned the 19 X what are your thoughts?
