The 4.5F Comp configuration pairs a hammer-forged, ported barrel with an integral compensator and an integral top port in the slide. This setup helps manage muzzle movement while keeping the full-size profile and sight radius. The 9mm chambering is supported by steel double-stack magazines with a standard 20+1 capacity.
The slide features a direct-mount optic interface, and this pistol arrives with a Viridian RFX11 micro reflex sight already installed. The optic presents a green dot reticle, complementing the iron sights that include a white-dot front and a U-notch rear.
Controls are modern and practical: the pistol uses a striker-fired action with a bladed trigger and a trigger safety, bilateral slide-stop levers, and a left-side magazine-release button. The textured black polymer grip includes interchangeable backstraps to fine-tune fit.
Construction is robust, with a black-finished polymer frame over a stainless steel receiver and a modular serialized internal chassis. The dust cover includes a five-slot Picatinny (1913) accessory rail for lights or lasers. Markings include “ECHELON,” “SPRINGFIELD ARMORY,” and “9x19,” with proof and origin stamps reading “HS PRODUKT • MADE IN CROATIA.”
Overall length is approximately 8.0 inches, and the pistol is presented in very good condition with a clean, mirror-finish bore. It comes complete with the original case, manual, mounted optic, and four magazines to support range or duty use right away.
