Heckler & Koch CC9 vs Smith & Wesson M&P 9 Shield Plus

Both are 9x19mm Parabellum micro-compact records in this directory. The M&P 9 Shield Plus is 2 mm / 0.07 in longer overall; the CC9 has the longer barrel by 5 mm / 0.22 in; the M&P 9 Shield Plus lists 1 round more of standard capacity. 2 fields are not comparable — overall height, weight — because the makers publish them on different measurement bases.

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.
