About this product
What is the Springfield Armory Echelon 4.0C 9mm 4-inch Gear Pac? It's a compact, optics-ready 9mm pistol designed for concealed carry and range training, featuring a factory-mounted Viridian RFX11 green-dot optic and four 10-round magazines. This configuration bridges the gap between daily carry reliability and optics-ready performance without requiring aftermarket gunsmithing. The Gear Pac bundle includes essential accessories that would typically cost $200+ separately, making it a practical choice for shooters who want immediate capability out of the box.
What is the Springfield Armory Echelon 4.0C Gear Pac used for?
This pistol is designed for concealed carry and defensive training scenarios where optic-ready performance matters. The 4-inch barrel provides a balance between concealability and sight radius, while the included Viridian RFX11 optic enables rapid target acquisition in low-light conditions. With four 10-round magazines, you can run through standard qualification courses without constant reloading.
How does the Springfield Armory Echelon 4.0C compare to the Sig Sauer P320 Compact?
The Echelon 4.0C outperforms the Sig Sauer P320 Compact in optics readiness and modularity. Springfield's Central Operating Group allows for complete fire control unit swaps without an FFL transfer, while the P320 requires serialized FCU replacement. However, the P320 has broader holster compatibility due to its longer market presence and aftermarket support.
What does it weigh and what are the dimensions?
Unloaded weight is 23.4 ounces with a 7.25-inch overall length and 5.25-inch height. The 4-inch cold hammer-forged barrel contributes to the forward weight balance, reducing muzzle flip during rapid strings of fire. These dimensions make it comparable to a Glock 19 in concealability but with better out-of-the-box optic mounting.
Who is this NOT for?
This package isn't suitable for shooters in unrestricted states who want higher capacity magazines. The included 10-round magazines are compliance-oriented, and while 17-round Echelon magazines exist, they're not included here. It's also not ideal for competitors who need race-ready triggers—the 5.5-pound break is service-grade, not match-grade.
What's in the box?
You get the pistol with factory-mounted Viridian RFX11 optic, four 10-round magazines, a padded range bag, and standard paperwork. The range bag measures 16x10x6 inches and has separate compartments for magazines and eye/ear protection. Missing are a cleaning kit and additional backstraps—expect to spend $30-$50 there if needed.
Is the Springfield Armory Echelon 4.0C Gear Pac worth it at $713.99?
At $713.99, this package delivers approximately $250 in added value versus buying components separately. The Viridian RFX11 alone retails for $229, and four magazines at $40 each total $160, making the bundle price effectively $324 for the pistol itself. Compared to buying a base Echelon and adding optics later, this saves you gunsmithing costs and zeroing time.

Frequently asked questions
- Is it compatible with Holosun 507C optics?
- Yes, the slide uses the Echelon's proprietary optics cut pattern, which requires an adapter plate for Holosun 507C. Springfield sells the plate for $49.95, and installation adds 3-5 minutes with a Torx T10 driver. Without the plate, the optic will not seat correctly.
- Does it fit Glock 19 holsters?
- No, the Echelon 4.0C has a unique frame geometry that requires specific holsters. Safariland ALS models for Echelon work, but most Glock 19 holsters will not retain it securely. Expect to spend $60-$100 on a dedicated holster from brands like Tier 1 Concealed or Vedder.
- How long does shipping take?
- FFL shipments typically take 3-5 business days once processed. Ironclad Armory uses UPS Next Day Air for firearms, but your local FFL's availability adds 1-2 days for transfer paperwork. Non-FFL items like the bag ship separately in 2-3 days via USPS.
- Can I return it if it doesn't fit?
- Firearms are final sale once transferred through an FFL due to federal regulations. Ironclad Armory allows returns on non-firearm items within 30 days, but the pistol itself cannot be returned unless defective. Inspect fit at your FFL before completing transfer paperwork.
- Does this work with SilencerCo Omega 9K suppressors?
- Yes, the 1/2x28 threaded barrel version (sold separately) accepts SilencerCo Omega 9K suppressors. This model comes with a non-threaded barrel, so you'll need Springfield's threaded barrel upgrade for $149.95 and a piston assembly for another $85.
