Springfield Armory Echelon 4.0C 9mm 4" 15-Round Pistol with Viridian RFX11 Optic

The Springfield Armory Echelon 4.0C Comp Gear Pac is a striker-fired 9mm Luger pistol built on a modular Central Operating Group, a serialized fire control unit that can be transferred between compatible frames. It is sold as a bundle that includes a factory-installed Viridian RFX11 green dot optic, aimed at shooters who want an optic-equipped compact pistol out of the box.

The pistol has a 4-inch barrel, a 15-round capacity, a black polymer frame with a compact frame size, and a black Melonite finish. The slide has compensator vents that direct gas upward to reduce muzzle flip during rapid fire. It carries 3-dot night sights for backup aiming, and the slide is optics ready. It weighs 1.49 pounds and measures 7.25 inches overall.
