Springfield Armory Echelon 4.0C U-Notch 4" Semiautomatic Pistol
Caliber
Canyon
The Springfield Armory Echelon 4.0C U-Notch 4” is a compact 9mm semi-automatic pistol designed for users seeking a modern, modular platform ready for demanding use in a more contained format than full-sized versions. Its 4-inch (101.6 mm) barrel, optics-ready slide, and U-Notch / U-Dot™ sight system make it a very balanced option for sport shooting, compact sidearm use, and professional application in accordance with current regulations.
This 4.0C version maintains the core characteristics of the Echelon platform, but with more compact dimensions. It incorporates aggressive slide serrations, a front trench, flared slide, oversized trigger guard, ambidextrous controls, and textured indexing points, offering comfortable handling and highly refined ergonomics.
The grip features adaptive texture, 3 sizes of backstraps, and 3 sizes of grip modules, allowing the weapon to be adjusted to different hands and grip preferences. Furthermore, its configuration with a 15-round flush-fit magazine and an 18-round extended magazine allows for alternating between greater compactness or higher capacity.
It is available in two colors: black and FDE, maintaining the same main technical specifications in both versions.
