Springfield Armory
Echelon 4.0FC Comp

Springfield's full-capacity Echelon 4.0FC Comp pairs a full-size black polymer grip module with a compact slide and a four-inch hammer-forged Melonite-finished barrel. The slide and barrel incorporate an integral compensator; the Variable Interface System supports direct mounting for a broad set of optics, and the serialized stainless-steel Central Operating Group can move between compatible grip modules. The exact page publishes a 7.25-inch overall length, 1.2-inch grip width, 24-ounce weight with the flush magazine, 25-ounce weight with the extended magazine, tritium/luminescent U-Dot sights, one 17-round and one 20-round magazine, SKU, UPC and MSRP. The launch release separately identifies 15-round SKU EC9409BFC-U-COMP15 / UPC 706397014322 and 10-round SKU EC9409BFCLC-U-COMP / UPC 706397014186 at the same MSRP; they are preserved here as related capacity variants rather than duplicated records. Guns.com's linked written review tests the exact full-capacity configuration over more than 500 rounds; Springfield supplied the review pistol, so that relationship is disclosed rather than treated as anonymous independent sourcing.
