Glock 19 Gen5 vs Walther PDP Full Size 4.5″

By Cole Harlan, EditorUpdated Nov 5, 2026How we verifyEditorial standards

The biggest printed difference is capacity and barrel: Walther lists 10 or 18 rounds and a 4.5-inch barrel on the PDP Standard Full Size (Item Number 2842475), while Glock lists a standard 15 rounds and a 102 mm (4.02 inch) barrel on the G19 Gen5. The Walther column is Walther’s product page; the Glock column is the G19 Gen5 technical-data table on Glock’s U.S. site. Checked November 5, 2026. This is the full-size 4.5″ PDP; for the 4″ compact, see PDP Compact 4″ vs Glock 19 Gen5.

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 because Walther does not say whether a magazine is in it. 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 the larger magazine option printed on the SKU: the Walther. Its page lists 18 Round (and 10 Round) capacity with two magazines included; Glock lists a standard 15, with optional 15 / 17 / 24 / 31 / 33.
If you want the shorter barrel and slide: the Glock. Glock lists 102 mm (4.02 inch) and a 174 mm (6.85 inch) slide; Walther’s page describes a 4.5-inch barrel and prints a slide length of 7.5 without units.
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 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.
