The Echelon 4.0C compact variant blends a 4 in barrel with a high-capacity 19+1 magazine system, delivering a compact footprint without sacrificing on-board capacity. The barrel hood is marked 9x19, and the included factory magazines have witness holes numbered to 15 for quick round counts.
Its Central Operating Group is a serialized stainless-steel chassis receiver that enables grip module swaps while keeping the fire control unit as the controlled component. The polymer grip module includes an under-cut trigger guard and a slight magwell flare, and ships with interchangeable backstraps to fine-tune fit.
The slide is finished in Desert FDE Cerakote and includes front and rear cocking serrations, a forward relief window, and a direct-mount optics interface covered by a two-screw protective plate. Sights are a U-notch rear with a white outline paired to a tritium front dot with a yellow ring for visibility.
Controls are modern and flexible, with fully ambidextrous slide stop levers and a reversible magazine release. An integral 3-slot Picatinny accessory rail on the dustcover supports common weapon lights. Proof and import markings read HS PRODUKT MADE IN CROATIA and S. GENESEO, IL.
