Springfield Echelon 4.0C Comp

The Echelon 4.0C Comp is Springfield's first compensated variant of the Echelon platform, scaled down from the 4.5F duty frame to a Glock 19-class compact and fitted with a one-piece barrel that incorporates an integrated compensator. The comp adds no length to the slide envelope, so Echelon 4.0C holsters generally fit without modification. The 4-inch barrel keeps overall length at 7.5 inches, between a Glock 19 and a Glock 17.

The Variable Interface System (VIS) carries over from the full-size Echelon and mounts most micro red dots directly to the slide with no adapter plate. Trijicon RMR, RMR HD, and SRO; Holosun 407C, 507C, and 508T; the Holosun EPS Carry; Leupold DeltaPoint Pro; and Shield RMSc footprints all seat directly. The larger Holosun 509T and Aimpoint ACRO footprints mount through a thin C&H Precision or Springfield adapter plate. The serialized Central Operating Group (COG) chassis also carries over, so the grip module swaps to small or large without an FFL transfer.

At the current $710 verified price ($749 MSRP), the Echelon 4.0C Comp offers a larger grip, full-length rail, more capacity, and no-plate optic mounting at a competitive factory-comp price. For shooters who want a duty-grade compensated carry pistol with maximum optic compatibility, the 4.0C Comp is the strongest argument against the P320 X-Carry and Glock 19X comp variants.
