SIG SAUER P226 Nitron Full-Size vs SIG SAUER P320 Full-Size

Both are 9x19mm Parabellum full-size records in this directory. The P320 Full-Size is 7 mm / 0.3 in longer overall; its barrel is 7.62 mm / 0.3 in longer; the P320 Full-Size lists 7 rounds more of standard capacity. One field is not comparable — 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.

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.
