The Springfield Echelon 4.0 FC 9mm With Aimpoint COA Red Dot brings the proven Echelon design into a more concealable footprint while keeping duty-ready performance. Its billet-machined slide with black Melonite finish is cut for Springfield’s Variable Interface System, allowing the included Aimpoint COA 3.5 MOA red dot to mount directly for a low, secure sight picture. A compact 4-inch barrel and shortened frame balance shootability with easier everyday carry, while tritium U-Dot sights back up the optic for confident aiming in varied light.

This Echelon 4.0 FC model is optimized for defensive carry and range training, offering a 15-round flush-fit magazine for minimal printing and an 18-round extended magazine when capacity matters most. The textured polymer grip frame promotes a stable hold, and the optics-ready slide with forward serrations supports fast manipulations. Whether used for concealed carry, home defense, or regular practice, it reflects Springfield Armory’s focus on modern ergonomics and thoughtful innovation.
