Glock prints each value in millimeters and inches and notes that its technical data “are rounded and do not reflect tolerances.” Neither commercial page has a slide stop or optic row, and the G43 text does not mention a rail, so those cells say Not yet verified rather than guess. Glock’s law-enforcement tables for these models did not load when we checked. We list no price.
Which to pick (on paper)
- If capacity is the deciding number: the G43X. Glock lists a standard 10-round magazine against 6 for the G43.
- If a short grip and light loaded weight matter most: the G43. Glock lists 108 mm (4.25 inch) height and 585 g (20.64 oz) loaded, against 128 mm (5.04 inch) and 654 g (23.07 oz).
- If you want the same slide and barrel: they are nearly identical on paper. Both list a 154 mm slide, 22 mm slide width and a 3.41 inch barrel.
We have not range-tested these; facts above are from Glock’s pages.
