Two 9mm pistols with optic provisions. The biggest cited difference is weight: Walther prints 23.30 oz without saying whether a magazine is included, and Springfield prints 21 oz with the flush magazine. Walther’s page title and copy give a 3.5-inch barrel; Springfield prints 3.7″. Checked November 5, 2026.

The makers do not measure alike. Walther prints one unlabeled “Dimensions” line and does not say which number is length, width or height, while Springfield prints length, grip width and height separately, so we do not match them number to number. Walther does not say whether 23.30 oz includes a magazine; Springfield’s 21 oz is with the flush magazine and 21.4 oz with the extended one. Walther’s page also lists a 1/2 x 28 thread pitch but marks Threaded Barrel as No, so we do not call it threaded. Capacity pairs only loosely: Walther lists 10- and 15-round options, Springfield ships a 15-round and a 17-round magazine. This is the F-Series Standard 3.5″, not the Compact covered in Walther PDP Compact vs Hellcat Pro. The price gap is not drawn here: the two prices are each maker’s printed MSRP on the check date.

Which to pick (on paper)

If you want the lighter printed weight: the Hellcat Pro, at 21 oz with the flush magazine against Walther’s 23.30 oz (bases differ).
If you want the slimmer printed grip: Springfield prints a 1″ grip width; Walther prints 1.34 in as its unlabeled middle dimension and slide width.
If you want a named trigger: the Walther page lists the PDT Performance Duty Trigger; the Springfield page we captured prints no trigger name.
If you want the larger printed magazine: the Hellcat Pro lists a 17-round magazine; Walther lists 10- and 15-round options.
If a factory-ready optic cut matters: Springfield lists the Hellcat Pro OSP as Optics Ready; Walther lists a plate-based cut with no plate included.

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