SIG SAUER P365 Nitron Micro-Compact vs Springfield Armory Hellcat 3" Micro-Compact
Both are 9x19mm Parabellum micro-compact records in this directory. The Hellcat 3" Micro-Compact is ≈5.4 mm / ≈0.2 in longer overall; the P365 Nitron Micro-Compact has the longer barrel by ≈2.54 mm / ≈0.1 in; the Hellcat 3" Micro-Compact 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.
