The makers do not measure alike. Walther prints a single unlabeled “Dimensions” line and Glock prints separate length, width and height, so we show them side by side without asserting which Walther number is which. Walther’s weight line may not be comparable to Glock’s three weights. Glock notes its data “are rounded and do not reflect tolerances.” Walther’s page lists a price; we do not, because street prices move.

Which to pick (on paper)

If you want a factory optic cut named on the page: the Walther. Its page lists “Optics Cut: Plate” (no plate or optic included). The Glock page we used does not print an optic row.
If you want the maker to print a standard 15-round figure: the Glock lists a standard 15; the Walther lists 10 or 15 round magazines on its SKU, with two included.
If you want separately published weights: the Glock prints weight empty, with an empty magazine and loaded.

We have not range-tested these; facts above are from the makers’ pages.
