Springfield Echelon Pro 4.0FC Comp

The Echelon Pro 4.0FC Comp pairs the full-size Echelon grip length with the 4-inch compact slide, the same crossover layout as the standard Echelon 4.0FC, and adds the Pro line's integral compensator, ported barrel, and Springfield Grey Cerakote slide. Springfield lists it at 24 ounces, 7.4 inches long, and 6.5 inches tall, with a medium grip module installed.

The 4.0FC is the capacity pick of the two 4-inch Pros. It ships with three 20-round magazines against the 4.0C's 18-rounders, and the longer grip gives a full hand on the frame while the slide stays at compact length. The removable machined-steel magwell, stainless steel guide rod, LightForged Badlands grip texture, tritium front sight with orange luminescent ring, and serrated black rear sight are the same Pro features found across all three sizes.

The serialized Central Operating Group (COG) and the Variable Interface System (VIS) carry over unchanged from the standard Echelon, so the 4.0FC accepts Echelon grip modules and mounts compatible optics directly to the slide without a plate.
