Heckler & Koch USP40 (V1) vs Heckler & Koch USP9 (V1)
Heckler & Koch publishes both as USP models. They are chambered differently — the USP40 (V1) in .40 S&W, the USP9 (V1) in 9x19mm Parabellum — so nothing below compares their cartridges. The two list the same overall length; both list the same barrel length; the USP9 (V1) lists 2 rounds more of standard capacity; the USP40 (V1) is 50 g / 1.76 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.
