Walther catalogues each barrel length and frame size as its own listing — Standard Compact 4 in and 5 in, Standard Full Size 4 in and 5 in, plus the F-Series, Pro, Match, Steel Frame, Two-Tone and California lines — and all are separate records under the base-model rule. Walther was previously recorded as unsourceable because waltherarms.com/sitemap.xml 404s; that was wrong. Its robots.txt declares a sitemap at a non-standard Joomla OSMap URL, the site returns real 404s rather than soft ones, and a plain browser user-agent is served normally with no challenge. Two extraction traps are documented in execution/extract_walther_specs.py and both nearly cost this record: the units live in a nested <small> tag — "8 <small>(Inches)</small>" — so a naive tag-strip yields a bare number that cannot be recorded, and the specification rows must be parsed one at a time, because a pattern spanning the document pairs "Color" with the length value four rows later. Walther publishes imperial only, so every metric value here is converted and flagged. Capacity: Walther lists "10 Round, 18 Round" and designates neither as standard; the description leads with 18, so 18 is recorded as standard and 10 as optional — the only judgement call on this record. Barrel length is not in the specification list at all and comes from the page's own description prose ("4.5-inch barrel length"), which is still the manufacturer's statement. Four fields are unrecorded because Walther does not publish them. Ignition, trigger action and operating system: the word "striker" does not appear on the page, and the "[PDT] Performance Duty Trigger" is a trigger name rather than an action class. Trigger pull: the page gives a "Trigger Weight Tolerance" of +/- 1 lb with no weight for the tolerance to apply to, which is not a specification. Slide finish: Walther publishes a Slide Color of Black, which is not a finish. Year introduced: no year appears anywhere on the product page and Walther publishes no launch announcement reachable from it. Overall height and weight carry a basis note because Walther does not state whether either includes a magazine. Walther also publishes a 7.5 in slide length, a 1.34 in slide width, polygonal rifling, a loaded-chamber indicator, a plate-type optics cut and a $699.00 MSRP, none of which has a schema field.

Verification boundary: Published technical data are rounded, may not reflect manufacturing tolerances, and may change without notice. MSRP is not recorded: most cited product pages do publish a price, but it changes without notice and independently of the specification, so this directory has no field for it and the row stays blank rather than carrying a figure that would silently go stale. Values marked ≈ were converted by this directory from the unit system the source published; the unmarked figure in the same row is the published one.

Evidence tiers backing this record: Manufacturer. Unmarked values come from manufacturer documentation; any value drawn from a lower tier is labeled inline with that tier. Where two sources disagreed, the higher tier was recorded and the disagreement noted.
