Scope note: SKU 365-9-BXR3, the base catalogue number on SIG's P365 Nitron Micro-Compact page. That page carries three SKUs: this one, 365-9-BXR3-MS (adds a manual safety) and 365-9-BXR3-MS-MA (Massachusetts-compliant); both are separate listings under the base-model rule. The wider P365 line — X, XL, X-Macro, Fuse, AXG, 380 — is separately catalogued and out of scope for this record. SIG is the first non-Glock manufacturer here to publish BOTH unit systems, so no value on this record is directory-converted. Its metric figures do appear to be SIG's own conversions from imperial — 3.1 in is exactly 78.74 mm, and the rounding is uneven across rows (147 mm, 27 mm, 109 mm) — but they are the manufacturer's published numbers, so both systems are recorded as published and none is flagged converted. Overall height and weight carry a basis note because SIG does not state whether either includes a magazine, the same gap as Ruger and Taurus. Trigger pull is unrecorded: SIG describes "the clean crisp trigger pull you expect from a SIG" but publishes no figure. Year introduced is unrecorded: SIG's press-release index returns a Cloudflare challenge, which this directory does not attempt to defeat, and no P365 launch release was found in the Web Archive — the same outcome as the G42, G43, G44 and Taurus TX22. Manufacturer size class is SIG's own "Micro-Compact", which normalizes to the directory's existing micro-compact frame class — the same class the G42, G43 and G43X already carry, reached there from Glock's own "Subcompact" and "Compact Slimline" labels. SIG is simply the first manufacturer whose published wording matches the normalized value directly. SIG also publishes a 4.9 in (123 mm) sight radius, a stainless-steel slide, a carbon-steel barrel and a $519.99 price, none of which has a schema field. The warranty is SIG's Infinite Guarantee, stated on the product page itself rather than on a separate warranty page — sigsauer.com/warranty is challenged — so the warranty row cites the product source.

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.
