Smith & Wesson M&P 9 Shield Plus

THIS RECORD CORRECTS A STANDING CLAIM ABOUT SMITH & WESSON THAT SHAPED THE SCHEMA. Both this directive and the expansion planning notes have said since 2026-08-12 that Smith & Wesson "publishes no overall length, width or height at all" — it was cited as one of two reasons the source policy was widened, and it is the stated reason `overallLength`, `overallWidth` and `overallHeight` were made optional. It is wrong. S&W publishes an overall length, an overall height, a sight radius and a frame width, on a spec-sheet PDF linked from the product page; the product page itself additionally renders weight, width and height. What was true is that none of it is in the page's HTML. S&W's site is a Next.js application and every specification lives in the `__NEXT_DATA__` payload under `customfields`, with the dimensions inside an HTML-in-JSON `customDimensions` string — so a fetch-and-grep for "Overall Length" returns nothing on a page that publishes one. That is the CZ lesson exactly (check the embedded payload before concluding a site publishes nothing), and it is worth noting the schema change it prompted was still correct for its other reason: PSA and Shadow Systems genuinely publish incomplete dimension sets. OVERALL WIDTH IS DELIBERATELY UNSET DESPITE TWO S&W SOURCES PUBLISHING A 1.1 IN FIGURE. The spec sheet labels it "Frame Width", with a sub-row reading "(Less Controls): .94 in"; the product page's dimensions block labels the same number plainly "WIDTH". Same measurement, two labels, and they mean different things — the Desert Eagle situation, where a manual's "Width" and a catalogue's "Slide Width" named one figure. The rule that settled that one applies here and points the other way: the document whose purpose is specification governs, and here it is the spec sheet that gives the more careful label. A frame width is not an overall width, the Springfield "Grip Width" call, so the dimensions row names the missing axis rather than implying a complete set. Both figures are recorded here instead. WEIGHT SITS IN `weightUnloaded` AND THE TEMPTATION TO PROMOTE IT IS SPECIFIC. S&W publishes "Weight: 17.9 oz. (507.5 g)" and, on a separate row, "Magazine Weight: 13 Round: 2.6 oz.; 10 Round: 2.2 oz." Listing the magazine's weight separately reads as though the pistol figure excludes it, which would put the value in weightWithoutMagazine — but S&W never says so, and reading a field's meaning off a neighbouring row is inference dressed as transcription, the PSA Dagger call. The magazine figures are recorded here so the reader can do the arithmetic the directory will not. Note also that BOTH magazine metric conversions are misprinted: the sheet gives 6.6 g for the 13-round and 6.6 g for the 10-round, where 2.6 oz is about 74 g and 2.2 oz about 62 g. That is a manufacturer misprint, left unrecorded like the G23's — and because it raises a fair question about the sheet's other metric figures, every one was checked and they are all correct: 7.9 cm for 3.1 in, 15.5 cm for 6.1 in, 11.7 cm for 4.6 in, 2.8 cm for 1.1 in, 2.4 cm for 0.94 in, 13.5 cm for 5.3 in and 507.5 g for 17.9 oz. The error is confined to the two magazine rows. S&W publishes both unit systems, so nothing on this record is converted and it carries no conversion legend; the metric side is re-expressed from centimetres to millimetres, which is a decimal shift within one system rather than a derivation (the Springfield Kuna's "4 lbs 10 oz" call) and so is not flagged. IGNITION IS RECORDED AND TRIGGER ACTION IS NOT. The sheet's Action row reads "Striker-Fired, Semi-auto": the first half states the ignition outright, and the second is a firearm class rather than one of this directory's cycling values, so `ignition` is striker-fired and `operatingSystem` is unset. Nothing anywhere states a trigger mode, so `triggerAction` is unset in the ordinary way — the maker publishes nothing on that axis, which is a different kind of gap from the Taurus G3c's (no directory value exists) and the Ruger LCR's (the maker's word spans two values). Frame class is transcription: S&W publishes "Frame Size: Micro-Compact", the same class the Hellcat, P365, G42, G43 and G43X carry. CAPACITY AND THE SKU. The sheet publishes "13+1 or 10+1 Rounds" and the features list says both magazines are included, so 13 is recorded as standard with 10 optional; the +1 is the chamber and this directory records magazine capacity. Separate listings under the base-model rule: the thumb-safety SKUs, the optics-ready models, the 10-round and state-compliant configurations, the threaded-barrel and PVD colours, the law-enforcement listings, the bundles, and the Shield Plus to Shield X conversion kits. THE WARRANTY IS TWO POLICIES AND FLATTENING THEM WOULD BE FALSE. S&W warrants defects notified in writing within ONE YEAR of purchase by the original owner; a separate Lifetime Service Policy then "begins after the warranty period has expired" and repairs functional defects for the lifetime of the original owner on any S&W handgun purchased on or after February 1, 1989 — conditional on returning the Product Registration Card within 30 days, and expressly excluding the finish, grips, magazines and sights. Calling that a lifetime warranty would merge two documents' worth of distinct terms; both are recorded. It scopes by class rather than by model list, so it covers this pistol without naming it, the Walther PPK reading. YEAR INTRODUCED IS UNRECORDED AND THE AVAILABLE DATE IS A TRAP. The product record embeds `date_created: 2022-12-07`, which is when this SKU's entry was created on S&W's commerce platform, not when the Shield Plus line was introduced — the Ruger LCP MAX `introDate` lesson in a clearer form, since here the date is a CMS timestamp rather than a catalogue number's. S&W's news page publishes no dated releases either; it embeds a Canto media portal instead. So no source read here dates the model, and the field stays empty, following the TaurusTX 22, PSA Dagger and CZ P-10 C. `availability: "disabled"` on the same record is likewise NOT a production status — S&W sells through dealers and the field governs its own cart; `is_visible` is true and the listing is live. No production claim is made either way, the G37/G38/G39 rule. Also published and unrecorded for want of a schema field: 1:10 five-groove right-hand rifling, a 5.3 in sight radius, a stainless barrel and slide both in an Armornite finish, a matte black polymer frame, an 18-degree grip angle, a flat-face trigger, two included magazines, state-compliance flags for CO, DE, IL and VT, and the $499 price the listing carried.
