Springfield's Echelon 4.0FC Comp Adds Porting Without Added Length
Springfield Armory has rolled out a new variant in its Echelon lineup, the 4.0FC Comp, a 9 mm striker-fired pistol that puts a full-size grip under a compact slide with a factory-milled compensator cut into both barrel and slide.
Snapshot
The Echelon 4.0FC Comp keeps a 17-round flush-fit magazine and full-length grip while trimming slide length to 4 inches, holding overall length to 7.25 inches. The integral compensator vents gas upward to curb muzzle rise without adding the length a threaded-on unit would.
Key points
- Compensator design: Ports cut into the barrel and slide direct gas upward, and Springfield Armory placed the front sight behind the ports to keep the sight picture clear.
- Size and weight: With the 17-round magazine the pistol is 5.5 inches tall and weighs 24 ounces; a included 20-round extended magazine adds an inch of height and an ounce of weight.
- Shared Echelon platform: The serialized Central Operating Group chassis swaps between grip modules, and the Variable Interface System reportedly mounts more than 30 optics without adapter plates.
- Build details: Hammer-forged barrel with 1:10-inch twist, billet-machined slide, Melonite finish, ambidextrous controls, and tritium/luminescent front sight paired with a Tactical Rack U-Dot rear.
- Pricing and options: MSRP is $784, with restricted-state versions shipping at 15 or 10 rounds for the same price, plus Gear Pac and Firstline variants.
Quick take
A milled-in compensator that doesn't add length is the real story here, letting shooters keep a full grip and 17-round capacity on a carry-size footprint. For anyone already in the Echelon ecosystem, the shared chassis and optics-mount compatibility mean this isn't a new system to learn, just a new slide option on the existing platform.
