Scope note: Glock lists this model only in MOS configuration — g40-gen4-mos is its sole product page, and the sitemap holds no non-MOS G40 — so the MOS page is recorded as the base record under the 2026-08-11 decision. The page's heading reads "GLOCK 40 Gen4 in MOS Configuration" while its title and header chip read "G40 Gen4 MOS"; the generation is recorded as Gen 4 MOS. Year introduced comes from the January 2015 release announcing the MOS platform, preserved only as a Web Archive capture: it announces the G34, G35 and G41 Gen4 MOS as released and the G40 as "coming soon", so 2015 is the year Glock announced the model, not necessarily the year it shipped. No later manufacturer source gives a ship date. The manual's spec table (p. 59) matches the product page on every recorded value. At 915 g without a magazine this is the heaviest record in the directory.

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.
