Scope note: SKU 320F-9-BSSP, the full-size configuration the model line is named for, chosen as the base record deliberately rather than by default: SIG titles this page simply "P320 FULL-SIZE", where every sibling carries a qualifier. The same page's second SKU, 320F-9-BSSP-10, is this identical pistol with 10-round magazines for capacity-restricted states, and is a separate listing under the base-model rule — as are the P320 Nitron Compact (320C-9-B), the Carry, XFive, XCarry, XTEN, AXG, Spectre, Pro and the M17/M18 military models, all of which the owner's manual covers alongside this one. TWO SIG FETCH BEHAVIOURS WORTH KNOWING BEFORE TRUSTING A RESULT. First, `p320-nitron-full-size` returns a Cloudflare "Just a moment..." interstitial, which is an actual bot challenge and out of scope — this directory does not attempt to defeat one, and the extractor's page_type check refused it rather than parsing the challenge page as data. Second, `p320` alone is a SOFT 404: HTTP 200 with a "Default Category" shell that canonicalises to all-products. Neither is evidence about what SIG publishes. A THIRD TRAP COST A REAL BUG AND WAS FIXED IN THE EXTRACTOR: SIG's SKU column is how the parser finds where the header row ends, and its pattern required three bare digits and a hyphen, which matches the P365's 365-9-BXR3 but not the P320's 320F-9-BSSP, where letters encode the frame size. Every P320 page therefore parsed as "0 catalogue rows" — a page full of published specifications reported as empty, which reads as SIG having changed its markup rather than as a too-narrow regex. The widened pattern was regression-checked against the P365 page and reproduces that record's values unchanged. SIG publishes both unit systems, as it does for the P365, so nothing on this record is converted. Two basis notes, and the difference between them is the point: SIG states the weight basis here — "28.3 oz [802.3 g] w/ Magazine" — where the P365 page states none, so a brand's disclosure habits cannot be assumed from one model. It is recorded under weightWithEmptyMagazine because SIG says a magazine is fitted, but the basis records that SIG never says the magazine is EMPTY; height carries the usual note because SIG does not say whether it includes a magazine. The action axes come from two sources. Ignition is striker-fired from the PRODUCT PAGE, whose column is labelled "TRIGGER ACTION" but whose value is "Striker" — SIG conflates the two axes itself, exactly as the P365 record documents — and the manual corroborates it. Operating system is recoil-operated from the MANUAL ALONE (§8.1, p. 12: "The P320 is a striker fired, mechanically locked, short recoil operated pistol"), so it carries an operatingSystemSource rather than borrowing the product page's footnote. Trigger action stays unset: SIG's "TRIGGER ACTION" column publishes an ignition value, and its "TRIGGER TYPE" row reads "Striker Fired w/Curved Trigger", which describes the shoe's shape rather than a trigger mode. Trigger pull is unrecorded — SIG publishes no figure for this model, the same gap as the P365. Year introduced is unrecorded: the P320 reached market in 2014, but SIG's live press index is behind the same challenge, and the archived press-release set — 183 captured URLs — begins in January 2017 and holds only department-transition announcements, not a launch. The manual describes the pistol family as having an interchangeable grip module, a reversible magazine catch and ambidextrous controls; those are deliberately kept OUT of the controls row, which is product-page-sourced, rather than blended across two sources under one footnote. Also published and unrecorded for want of a schema field: a 6.5 in / 165 mm sight radius, a DLC-coated carbon steel barrel, a stainless steel slide and fire control unit, the PRO optic footprint, and an M1913 accessory rail.

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.

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.
