The Echelon’s serialized Central Operating Group steel chassis anchors a durable polymer frame and a billet-machined steel slide finished in Black Melonite. Ambidextrous slide stop controls and an integral Picatinny (1913) accessory rail support practical use without adding complexity.
Its 4.5 in steel barrel is cold hammer-forged with a Melonite finish, a non-threaded profile, and a flush crown. The 1:10 twist and sharp conventional rifling complement the bright, clean bore noted in the condition.
The slide incorporates Springfield’s Variable Interface System for direct-mount optics. This pistol arrives with a Crimson Trace micro reflex red dot installed (5 MOA dot), while the factory U-Dot tritium/luminescent sights remain in place: a green tritium/luminescent front dot paired with a Tactical Rack U-notch rear.
Chambered in 9mm Luger, this full-size striker-fired configuration carries 21+1 capacity and includes two factory steel magazines with extended base pads. The model is the non-threaded 4.5F U-Dot variant identified by MFG part number EC9459B-U. It bears the “HS PRODUCT MADE IN CROATIA” marking and was manufactured by HS Produkt in Croatia for Springfield Armory, with the box and factory test target matching the firearm’s serial.
