SIG SAUER P226 Nitron Full-Size vs Walther PDP Standard Full Size 4.5"

Both are 9x19mm Parabellum full-size records in this directory. The PDP Standard Full Size 4.5" is ≈7.2 mm / ≈0.3 in longer overall; its barrel is ≈2.54 mm / ≈0.1 in longer; the PDP Standard Full Size 4.5" lists 8 rounds 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.
