The Springfield Armory Echelon 4.0 FC is a semi-automatic pistol in 9mm Luger with a 4-inch barrel and Melonite Black finish. This variant ships with two 10-round magazines and includes a front tritium sight and U-Dot rear sight. The slide is optic-ready, and the FC frame configuration is standard across the Echelon line.

• Front tritium and U-Dot rear night sights 
• Two 10-round magazines included

Owners who pick up the Echelon 4.0 FC in the 10-round configuration often do so for compliance reasons or for range use where high-capacity magazines are not needed. The night-sight package with front tritium and U-Dot rear is consistently called out as a practical inclusion that does not require an immediate optic purchase.

The 4-inch barrel and FC frame handle the same as the higher-capacity Echelon variants, so ergonomic feedback is largely the same: grip texture and the modular fit system earn praise, and the Melonite finish is noted for durability. Shooters transitioning from polymer-frame competitors find the grip angle familiar.

The 10-round limit is a trade-off some owners accept without complaint, while others note it as a practical limitation for home-defense use compared to the 15-round version. The trigger, as with other Echelon variants, is workable but draws requests for a lighter, shorter-reset option from more experienced shooters.
