Glock’s U.S. site carries the full Dimension tables for these two models on its law-enforcement product pages, which is where every number above comes from; we do not cite any other page for them. Glock prints each value in millimeters and inches, and notes that its technical data “are rounded and do not reflect tolerances.” We list no price: Glock’s law-enforcement pages do not print an MSRP.

Which to pick (on paper)

If you want the larger standard magazine: the G17 Gen5 lists a standard capacity of 17; the G19 Gen5 lists 15.
If overall size and weight matter most: Glock lists the G19 Gen5 at 185 mm (7.28 inch) long and 128 mm (5.04 inch) high including the magazine, against 202 mm (7.95 inch) and 139 mm (5.47 inch) for the G17 Gen5.
If barrel length is the deciding number: 114 mm (4.49 inch) on the G17 Gen5 vs 102 mm (4.02 inch) on the G19 Gen5.
If grip and slide width matter: Glock lists the same 34 mm overall width and 25.5 mm slide width for both.
If you want a G19-length slide on a G17-height grip: that is the Glock 45.
