Springfield Armory Echelon 4.0FC Handgun 9mm Luger 15rd (1) & 18rd (1) Magazines 4″ Barrel Black w/COA

Overview

The Springfield Armory Echelon 4.0FC is a 9mm striker-fired semi-automatic handgun designed to combine a compact slide assembly with a full-length grip frame. It features a 4-inch hammer-forged barrel and a serialized Central Operating Group stainless steel chassis, which allows for modular grip adjustments. The slide is billet-machined with a Melonite finish and includes the Aimpoint A-CUT direct interface, which allows for the factory-installed Aimpoint COA closed-emitter red dot sight to be mounted directly to the slide without adapter plates. The pistol measures 7.25 inches in overall length, weighs 24 ounces, and has a 1:10 barrel twist. This configuration provides a 17-round flush magazine capacity and an 18-round extended magazine capacity (noted as 20-round in some configurations). The firearm includes a black polymer small grip module, a captive recoil system, and a trigger safety. It is designed for applications requiring high magazine capacity in a maneuverable, duty-length frame.
