The P365-XL is ≈15.6 mm / ≈0.6 in longer overall; its barrel is ≈17.78 mm / ≈0.7 in longer; the P365-XL 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.

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; Hellcat 3" Micro-Compact: with flush magazine; 4.5 in with the extended magazine). Widths are not drawn because Hellcat 3" Micro-Compact publishes no overall width.
