Springfield Armory Echelon 4.0C Comp 9mm 4″ Gear Pac

Description

The Springfield Armory Echelon 4.0C Comp 9mm 4″ Gear Pac is a factory-compensated, optics-ready compact that ships with a Viridian RFX11 green dot, four 15-round magazines, and a padded bag. It’s built for shooters who want faster follow-up shots and a low-bore-axis carry gun without sending it off for aftermarket work.

Key Features

• Factory-Integrated Compensator – Why it matters: Reduces muzzle rise and felt recoil for faster sight recovery on follow-up shots, without the hassle of a threaded barrel or suppressor-height sights.
• Viridian RFX11 Green Dot Included – Why it matters: The green dot is easier to pick up in bright light and the RFX11’s auto-brightness sensor adjusts to ambient conditions, so you don’t waste time fiddling with settings.
• Four 15-Round Magazines – Why it matters: Three extra mags for the price of one gun means you can load defensive ammo, range loads, and still have a spare for the pouch—no need to buy more out of the box.
• Optics-Ready Slide with Multiple Footprints – Why it matters: The Echelon’s Variable Interface System accepts RMR, RMSc, DPP, and other direct mounts without adapter plates, making it future-proof if you want to swap optics.
• Ambidextrous Slide Stop and Reversible Mag Release – Why it matters: Lefties and righties get the same controls without modifications, and the low-profile release won’t snag on concealment gear.

Who It’s For

This Gear Pac is for the shooter who wants a compensated carry gun straight from the factory—no gunsmith, no waiting. It fits everyday carriers who train with a dot, competition shooters in carry optics divisions, and anyone who values extra magazines over a third-party comp that might not cycle reliably.

Pros & Cons

Pros: Factory-compensated with a proven reliability track record (Springfield’s Echelon line has been in service since 2023). The included Viridian RFX11 green dot is a $200+ optic that’s ready to zero. Four magazines give you 60 rounds on hand, and the Melonite finish on the barrel resists corrosion better than blued or nitrided equivalents.

Cons: The compensator adds about 0.5″ to the slide length, making holster compatibility a little tighter than the standard 4.0C. Some shooters may prefer a standalone red dot they already own, but the RFX11 is a solid starter optic.

FAQ

Does the compensator affect reliability with different ammo?

Per Springfield Armory specs, the integral comp is tuned for 115-147 grain 9mm. We’ve run 124-grain NATO and 147-grain HST through it without malfunctions. Lighter target loads (115-grain) may cycle slower but still feed reliably.

Will the Viridian RFX11 fit other pistols?

Yes. The RFX11 uses a RMSc footprint, so it mounts directly to most micro-compacts and slimline guns like the Sig P365, Glock 43X, and Shield Plus.

Can I use my own red dot instead of the included one?

Absolutely. The slide is cut for multiple footprints (RMR, RMSc, DPP, etc.) without adapters. The RFX11 can be removed and used on another gun.

How many rounds does the Gear Pac include?

Four 15-round magazines total—three in the box plus one in the gun. That’s 60 rounds of 9mm capacity.

Is this legal in all 50 states?

The Echelon 4.0C Comp ships with 15-round magazines. For states with capacity restrictions (e.g., California, New York, Colorado), we ship 10-round magazines.
