Springfield Armory Echelon Pro 4.0FC Comp, 9mm, 4", 20rd, Black/Gray, Pistol The Springfield Armory Echelon Pro 4.0FC Comp combines a ported 4-inch hammer-forged barrel with three 20-round magazines in a 7.4-inch-long 9mm pistol. The Pro configuration brings an integral slide compensator, an optics-ready billet-machined slide and a medium LightForged grip module with Badlands texture. Its combination of a 4-inch barrel and 20-round magazine capacity makes the 4.0FC a distinct choice for shooters who value substantial magazine capacity in a handgun with a compact overall length. This Black/Gray model features a Springfield Gray Cerakote H-304 slide over a black polymer frame. It measures 6.5 inches high, has a 1.2-inch grip width and carries a stated weight of 24 ounces. A magwell, tritium/luminescent front sight and black serrated rear sight complete the principal factory features. Shop the Echelon Pro 4.0FC Comp at BattleHawk Armory for integral compensation, an optics-ready slide and three included 20-round magazines. Factory Compensation with a 4-Inch Hammer-Forged Barrel The ported 4-inch steel barrel is hammer forged, finished in Melonite and specified with a 1:10 twist. Its porting works with the integral slide compensator to manage muzzle gas, helping limit muzzle rise and support a more settled sight picture between shots. The compensating features are built into the barrel-and-slide configuration, so they are part of the pistol as supplied. The 4.0FC maintains a 7.4-inch overall length while providing the Pro model's specialized muzzle treatment. The combination gives this pistol a clear identity: a 4-inch ported barrel, an integral compensator and a grip configuration supplied with 20-round magazines. The Melonite-finished steel barrel adds a durable surface treatment to the hammer-forged construction. Springfield Gray Slide with Optics Readiness The billet-machined slide combines a Melonite finish with Springfield Gray Cerakote H-304. That gray exterior contrasts with the black LightForged frame and identifies this specific color configuration. The slide incorporates the compensator and is optics ready, bringing the pistol's sighting options and compensated design together in one factory assembly. Select an optic and mounting components that are specifically compatible with the Echelon Pro 4.0FC Comp slide. Confirm the mounting interface and hardware requirements before purchasing accessories. An optics-ready slide provides the mounting provision for an appropriate sight, but it should not be treated as a universal fit for every pistol optic. Badlands Grip Texture, Magwell and Three 20-Round Magazines The black LightForged polymer frame uses a medium grip module with Badlands texture. Its patterned surface gives the hand a defined gripping interface, while the 1.2-inch grip width specifies the dimension across the grip itself. The included magwell creates a more defined opening to help guide magazine insertion. Three 20-round magazines are included with this 4.0FC configuration. Matching capacities keep the magazine setup consistent, and the three-magazine supply gives you multiple magazines for range sessions. Each magazine offers a 20-round capacity, making the included equipment a useful part of the pistol's overall value. Clear Iron Sights and a Stainless Steel Guide Rod A tritium/luminescent front sight pairs with a black serrated rear. The contrasting front reference draws visual attention, while the subdued rear provides a straightforward alignment reference. Serrations on the rear sight help reduce distracting reflections, making the iron sights a purposeful part of this optics-ready pistol. The captive recoil system uses a stainless steel guide rod and retains the spring assembly as a unit. At a stated 24 ounces, the complete pistol remains clearly specified for weight as well as size.
