SIG SAUER P365-XL vs Smith & Wesson Equalizer

Both are 9x19mm Parabellum micro-compact records in this directory. The Equalizer is 3 mm / 0.15 in longer overall; the P365-XL has the longer barrel by 0.98 mm / 0.03 in; the P365-XL lists 2 rounds more of standard capacity. 3 fields are not comparable — overall width, 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.

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 (P365-XL: magazine state not stated by SIG SAUER; Equalizer: with the 10-round magazine). Widths are not drawn because the widths are not published on one stated basis (P365-XL: no basis stated; Equalizer: labelled "Width" by Smith & Wesson, without saying which part of the pistol it spans).
