Springfield Armory Echelon 4.0C Comp 9mm 4" 10-Round Pistol with Viridian RFX11 Gear Pac

The Springfield Armory Echelon 4.0C Comp Gear Pac is a striker-fired, polymer-framed 9mm pistol sold as a bundle with a factory-mounted Viridian RFX11 green dot optic. It is built for compact carry and general-purpose shooting with a 4-inch barrel and a compensated slide with integrated ports intended to reduce muzzle rise during rapid fire.

The pistol has a 1:10-inch twist rate, a Black Melonite finish on the slide and barrel, and a Central Operating Group that can be transferred between frames. It uses a trigger safety rather than a manual safety, carries a 10-round capacity, and weighs 23.9 ounces with an overall length of 7.25 inches. The slide is optics ready, and 3-dot night sights serve as backup.

The package includes four magazines, the Viridian RFX11 optic, and a Springfield range bag.
