Springfield Armory Echelon Alpha 4.0C 9mm 4" 10rd CA Compliant Pistol

The Echelon Alpha 4.0C is Springfield's entry point into the Echelon system. The serialized Central Operating Group is the same modular chassis the full size Echelon runs on, which means the grip module and the slide are components rather than the gun itself and can be changed later without changing the serial number. The 4" barrel is hammer forged steel with a 1:10 twist and a Melonite finish, and the compact frame keeps the footprint close to what most people actually carry every day.

Optic mounting uses Springfield's Variable Interface System, a pattern of threaded holes and locating pins that lets most current red dots bolt straight to the slide with no adapter plate stacking height onto the gun. Backing that up is the U-Dot sight system, a wide rear notch paired with a front dot that lines up quickly under stress. The slide is recontoured with a polymer cover plate over the optic cut, and the backstrap carries Springfield's adaptive grip texture, which bites harder the tighter the hand closes on it. This is the California configuration: one 10 round stainless steel magazine, a magazine disconnect and a loaded chamber indicator. Everything else is standard Alpha.
