Scope note: SKU EC9459B-U, a current listing. Springfield marks retired SKUs "Discontinued:" in the product title, and most of the original Echelon listings are — including the white-dot launch SKU, the 3-dot tritium and both manual-safety variants. Six of the first ten checked were discontinued, so all forty base Echelon SKUs were enumerated from sku-sitemap.xml and filtered on that flag rather than picked by intuition; the Compact, Comp, threaded, Pro, Alpha and FirstLine configurations are separate listings under the base-model rule. Springfield qualifies its measurements more carefully than any other manufacturer in the directory, and the qualifiers are recorded rather than discarded: it publishes TWO weights and TWO heights, one of each per magazine type. The flush-magazine figures are recorded as the base configuration with the extended-magazine figures named in the basis, so nothing is silently dropped. The weight sits in weightWithEmptyMagazine because Springfield states a magazine is fitted; it moved there from weightUnloaded on 2026-08-12, when that choice was normalized across this record, the Hellcat and the SIG P320 so all three group together in the compare table. Overall width is unrecorded: Springfield publishes a Grip Width of 1.2 in, which is a different measurement and is not filed as an overall width. Warranty is unrecorded: Springfield's warranty lives on a client-rendered Inertia application at support.springfield-armory.com whose HTML payload carries only navigation, and the archived capture has the same limitation — the text is not obtainable without executing JavaScript, which this session cannot do. Ignition, trigger action and operating system are unrecorded: Springfield describes a captive recoil system, which is a component rather than an operating-system classification, and never states the ignition. Manufacturer size class and directory frame class are unset; the "4.5F" in the model name plainly encodes a barrel length and a frame designation, but expanding an abbreviation the manufacturer never expands is inference, not transcription. Springfield publishes imperial only, so every metric value is converted and flagged. Also published and unrecorded for want of a schema field: 1:10 twist, a hammer-forged Melonite barrel, a billet-machined optics-ready slide, and a medium grip module.

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.
