Springfield Armory
Echelon Central Operating Group
Springfield Armory released the serialized Central Operating Group as a standalone foundation for custom Echelon builds. The exact maker page confirms the 9mm chambering, black finish, Echelon-compatible frame and magazine pattern, 4.3-inch length, 1.9-inch height, three-ounce weight, $295 MSRP, SKU EC9900-RET and UPC 706397012373. Springfield describes stainless-steel COG construction, tool-steel trigger components, a flat-faced trigger with integrated safety, an included takedown lever and a secondary sear intended to help prevent unintended discharge if dropped. Compatible grip modules, slide assembly, barrel, sights, magazines and accessories are sold separately, so this is not a complete pistol. Production quantity and independent sell-through remain unpublished. The linked exact-edition clip and accompanying Springfield-owned article document a custom build around the standalone COG; they are promotional publisher material, not an independent endurance or live-fire review.
