SPRINGFIELD ARMORY ECHELON 4.5F (U-NOTCH) *15-ROUND*

The Springfield Armory Echelon 4.5F 15-Round model offers an uncompromised full-size duty pistol configuration tailored specifically for shooters in capacity-restricted states. Factory-equipped with two 15-round magazines, this model meets the legal guidelines of 15-round threshold jurisdictions while preserving the exact frame geometry, recoil management, and premium features of Springfield’s flagship striker-fired platform.

At the center of the Echelon's design is the Central Operating Group (COG)—a self-contained, serialized stainless steel chassis that houses the entire firing mechanism. This modular blueprint allows you to easily remove the serialized core and swap between different aftermarket or factory polymer grip modules to perfectly customize the pistol’s fit. The standard full-size frame features aggressive Adaptive Grip Texturing and interchangeable backstraps, ensuring superior weapon control and comfort under demanding conditions.

The billet-machined slide is outfitted with the patent-pending Variable Interface System (VIS), an innovative direct-mount optics framework. By utilizing a system of self-locking pins rather than traditional, thick adapter plates, the VIS allows over 30 popular red dot optics to sit exceptionally low on the slide for an intuitive sight picture and direct co-witnessing. Outfitted with a high-visibility tritium front night sight, a tactical rack U-Dot rear sight, and fully ambidextrous slide stops and magazine releases, the Echelon 4.5F 15-round pistol delivers duty-grade defense wherever compliance matters.

This model is chambered in 9mm Luger and features Springfield's signature u-notch tritium sight. Two 15-round magazines are included along with a Springfield soft pistol case.
