Glock 19X vs Glock 45

By Cole Harlan, EditorUpdated Nov 5, 2026How we verifyEditorial standards

Both are “crossover” 9mm pistols: a full-size frame with a compact slide. Glock’s own G45 text says it builds on the design Glock developed for the G19X. Every figure is copied from the technical-data tables on Glock’s U.S. law-enforcement product pages, checked November 5, 2026. Glock’s commercial-path pages for these models returned not-found that night, so we used the law-enforcement pages.

Glock prints each value in millimeters and inches and notes that its technical data “are rounded and do not reflect tolerances.” Neither page has a rail or optic row, so those cells say Not yet verified rather than guess. The G19X text lists a Glock Marksman Barrel, no finger grooves, ambidextrous slide stop levers and a lanyard loop, and says it ships with a standard 17-round magazine, two 17+2-round magazines and a coyote-colored case; the G45 page says none of that, so we do not claim the G45 lacks it. We list no price.

Which to pick (on paper)

If you want the lighter pistol: the G45. Glock lists 860 g (30.34 oz) loaded against 890 g (31.39 oz) for the G19X.
If you want the slimmer grip: the G19X, at 33 mm (1.30 inch) overall width against 34 mm (1.34 inch).
If you want more optional magazine sizes: the G45. Glock lists optional 19 / 24 / 31 / 33 against 19 / 24 for the G19X.
If you care about the coyote slide: the G19X. Glock’s G45 page title says Black.

Barrel, overall length, slide length, height and trigger pull match on paper. We have not range-tested these; facts above are from Glock’s pages.
