Description
Springfield built the Echelon 4.0 FC to settle a long-running debate among shooters: do you want the fast handling of a compact, or the control and grip room of a full-size? This one gives you both. It mates the short 4-inch slide and barrel from the compact 4.0C with a full-length "FC" grip module, so your whole hand gets purchase on the gun while the lighter slide cycles quick and snaps back on target. The result feels familiar to anyone who has run a duty pistol, just trimmed down where it counts.
At the heart of it is Springfield's Central Operating Group, a serialized stainless steel chassis that drops into different grip modules in seconds. It is the part that makes the Echelon a true modular platform you can grow with over time. Up top, the optic-ready slide uses the Variable Interface System, which lets you mount over 30 popular red dot footprints directly to the slide using configurable self-locking pins. No adapter plates, no aftermarket milling. This Gear Pac arrives with a Viridian RFX11 green dot already installed, so you can zero it and go.
For backup or iron-only shooting, you get a tritium front sight with a tactical-rack U-Dot rear that co-witnesses with the optic and grabs your eye fast in low light. The hammer-forged barrel wears a Melonite finish for solid corrosion and wear resistance, and the controls are fully ambidextrous, which is a real plus for lefties and anyone who trains both hands.
This is the California-compliant configuration, built around 10-round magazines while keeping the same handling and modular bones as the standard model. The Gear Pac bundle is the big draw here: four magazines, the factory green dot, and a heavy-duty zippered nylon range bag with storage for your gear. It is a strong fit for everyday carry, home defense, training, and range work, and a smart pick if you would rather skip piecing a setup together later and just get shooting.

Frequently Asked Questions
What comes in the Gear Pac bundle?
This Gear Pac ships with the Echelon 4.0 FC pistol, a factory-installed Viridian RFX11 green dot optic, four 10-round magazines, and a heavy-duty zippered nylon range bag with storage compartments. It is set up to go straight to the range with no extra accessories to track down. You essentially get the gun and most of the gear you would buy separately in one box.
What makes the 4.0 FC different from the other Echelon models?
The 4.0 FC combines the shorter 4-inch slide and barrel of the compact 4.0C with the full-length grip module of the full-size 4.5F. That gives you a gun that cycles fast and carries easier while still letting your whole hand grip the frame. Springfield calls it a do-it-all platform that bridges compact carry guns and full-size duty pistols.
Can I mount a different red dot besides the included Viridian?
Yes. The slide uses Springfield's Variable Interface System, which accepts over 30 popular optic footprints by configuring self-locking pins, so there is no need for adapter plates or aftermarket milling. If you decide to swap the Viridian for a different dot down the road, you can do it directly on the slide. The deep optic cut also lets dots sit low enough to co-witness with the iron sights.
Why does this version only hold 10 rounds?
This is the California-compliant configuration of the Echelon 4.0 FC, which is built around 10-round magazines instead of the standard 17-round mags. It keeps the same modular chassis, handling, and feature set as the regular model. You still get four magazines in the Gear Pac bundle, so spare capacity for the range or training is covered.
Are the iron sights usable in low light?
They are. The 4.0 FC comes with a tritium front sight that glows in the dark paired with a tactical-rack U-Dot rear, which gives you a fast, intuitive sight picture day or night. They also co-witness with the included green dot, so you have a reliable backup if the optic ever goes down.
