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.
