Standard capacityIdentical figures
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. Heights are not drawn because the heights are not published on one stated basis (PX4 Storm Full Size (Type F): magazine state not stated by Beretta; P320 Full-Size: magazine state not stated by SIG SAUER).
