As much as I like Glock (owned them since my first G17 "Gen1" serial number BH590, in 1988), they have really screwed the pooch a bit recently.
First, they should have called the G19X the G17S instead, which would have removed most of the confusion about it, and if they were going to bring out a copy of their military trials submission, at least bring out an exact copy. Second, they should have brought out a black version with the same model number, leaving the G45 number free for their commander sized single stack .45. Third, they should not have brought out their "concealed carry" G43X and G48 in silver, and gone straight to black.
Just my 0.02.
