The 4.5-inch steel barrel is hammer-forged, ported, and features an integral compensator, all treated with a Melonite finish. The slide is billet-machined, ported, and finished to match, delivering a durable black Melonite exterior.
The Echelon’s Variable Interface System (VIS) provides direct mounting for optics, and this pistol includes a Viridian RFX11 already installed. Iron sights consist of a tritium/luminescent front with a high-visibility green ring and a Tactical Rack U-Dot rear.
Its polymer frame is full-size with aggressive texturing, an undercut trigger guard, indexing pads, and interchangeable backstraps; two additional backstraps are included. A flared, removable magazine well funnel is installed to speed reloads, and a full-length 4-slot Picatinny accessory rail is integrated up front.
The striker-fired action uses a flat-faced trigger with an integral safety tab and a trigger safety system. Ambidextrous slide stop levers support left- and right-handed operation.
Capacity is 19+1 with the included extended magazine, and a 17-round flush-fit magazine is also provided. The pistol bears "Made in Croatia" and Geneseo, IL markings, features three-location serialization (slide, barrel, frame), and utilizes the Central Operating Group (COG) removable chassis. Model and serial are confirmed on the box label.
