Jeremy Tremp explores the new Springfield Armory Echelon 4.5F Comp handgun in a detailed article for The Armory Life, published on September 24, 2024. The Echelon 4.5F Comp, chambered in 9mm and featuring a 4.5-inch barrel, is praised for its reduced muzzle rise and recoil, thanks to its integral compensator and Variable Interface System (VIS) for mounting red dot optics. This model builds on previous successes from the Hellcat Pro Comp and Springfield Prodigy Comp, incorporating a self-contained serialized Central Operating Group for easy customization. Tremp tested various ammunition types at the range, lauding the gun's robust, user-friendly features like adaptive grip texture, and ambidextrous controls, which make it a reliable and accurate firearm for both casual and professional use, with an MSRP of $749.
