Glock G42 vs Glock G43X

Glock publishes both as Slimline models. They are chambered differently — the G42 in .380 ACP, the G43X in 9x19mm Parabellum — so nothing below compares their cartridges. The G43X is 14 mm / 0.56 in longer overall; its barrel is 4.5 mm / 0.16 in longer; the G43X lists 4 rounds more of standard capacity; the G43X is 120 g / 4.23 oz heavier under matched conditions.

How these differences are computed: each is the arithmetic difference between the two published figures, and it is only shown where both sources measured the field the same way. Where a source states a measurement basis the other does not match, the row says so instead of subtracting — figures on different bases are not comparable even when the numbers sit side by side. Differences marked ≈ involve at least one figure this directory converted between unit systems, so the difference is no more precise than that conversion.

Boxes, not silhouettes: makers publish a pistol's overall envelope, not its shape, so that is all this draws. Every box is aligned at the rear and drawn at one fixed scale, the same on every page of this site, so drawings compare across pages. It is not life-size on your screen.
