Glock prints each value in millimeters and inches and notes that its technical data are rounded and do not reflect tolerances. Weights are shown on Glock’s three bases (without magazine, with empty magazine, with loaded magazine) and each row compares the same basis. The G19X text calls it a crossover and lists a coyote color and a standard 17-round magazine plus two 17+2-round magazines in the box; the G17 Gen5 page we read says none of that, so we do not claim it lacks them. We list no price. For the G17’s long-slide cousin see Glock 34 vs G17.

Which to pick (on paper)

If the shorter barrel and length matter: the G19X, at 102 mm barrel and 189 mm overall against 114 mm and 202 mm.
If you want the longer line of sight: the G17 Gen5, at 164 mm (steel) against 152 mm for the G19X.
If you want more optional magazine sizes: the G17 Gen5. Glock lists optional 19 / 24 / 31 / 33 against 19 / 24 for the G19X.
If the loaded weight matters: the G19X at 890 g (31.39 oz) against 945 g (33.33 oz) for the G17 Gen5. Without a magazine the two are 625 g and 630 g.
If grip height or trigger pull decide it: Glock lists the same 139 mm height and 26 N for both, so they do not separate the two on paper.

We have not range-tested these; facts above are from the makers.
