Echelon 4.5" Gear Pac

The Springfield Armory Echelon 4.5" Full-Size Gear Pack is the duty-size build of Springfield's modular striker-fired pistol, paired with a holster, magazines, and accessories in a complete carry or duty bundle. Built on the Central Operating Group (COG) chassis Springfield's fully serialized, removable fire-control assembly the Echelon delivers genuine cross-platform modularity in a class where most competitors only offer parts-swap upgrades. The 4.5" full-size barrel and slide give the pistol the duty footprint shooters expect from a service pistol. Configured for Massachusetts compliance with 10-round magazines.

The COG chassis is the most distinctive engineering choice on the Echelon a single serialized firearm that migrates between grip modules of different sizes, in contrast to the typical striker-fired pistol where the frame is the serialized component. The Variable Interface System (VIS) is Springfield's direct-mount optic solution, accepting most popular red-dot footprints without an adapter plate or its associated stack-height increase. The Adaptive Grip Texture provides aggressive purchase under recoil while remaining comfortable against bare skin, and the trigger is one of the cleaner striker-fired pulls available out of the box.
