The Springfield Armory Echelon 4.5F 15-Round Desert FDE brings full-size tactical performance and premium modularity to users living in states with a strict 15-round magazine capacity limit. Chambered in 9mm Luger, this full-sized handgun features a 4.5-inch cold hammer-forged steel barrel and a slide beautifully finished in a durable Desert FDE Cerakote. It is built entirely around the self-contained, serialized Central Operating Group (COG) chassis system and employs the plate-free Variable Interface System (VIS) for direct, ultra-low red dot integration. Designed to meet state-specific regulations while retaining duty-sized ergonomics, this model configuration substitutes the standard high-capacity options to include two flush-fitting 15-round magazines.
