In 2025, Aimpoint announced a new red dot sight, the COA, with the unique A-CUT mounting system with a one-year exclusive partnership with Glock. In 2026, the market opened to other manufacturers to adopt the COA / A-CUT combo, and Springfield Armory took advantage with their Echelon pistols. This is an overview of the Springfield Armory Echelon x Aimpoint COA.
At War HOGG Tactical, I look at every duty setup the same way: as a system. A pistol and optic alone are not a duty system. The system is pistol, optic, mounting interface, back-up iron sights, weapon-mounted light, duty holster with retention, belt setup, and the training reps to make it all run together.
If any one piece is weak—a shifting mount, a failing optic, a binding holster—the shooter’s confidence and performance drop. And in a deadly force encounter, confidence and performance are not optional. That’s the difference between going home and not.
The War HOGG Overview
A War HOGG overview is a professional evaluation of a platform and system based on duty practicality, design, and early performance indicators, paired with a series of drills.
A War HOGG review is long-term: 90+ days, multiple environmental conditions, and 10,000 plus rounds of mixed ammunition.

The Aimpoint COA
The Aimpoint COA is an enclosed-emitter pistol optic designed for hard use, duty, and concealed carry. The enclosed design protects the emitter from the stuff that could block the LED emitter: lint, dirt, and rain.
The COA’s dot size is duty-practical, and the constant-on battery concept matters because you don’t want an activation ritual when your brain is already behind the power curve. If you carry a dot on duty, it needs to be ready when you’re ready.
The side battery tray matters because it allows battery changes without removing the optic and disturbing the system.
The A-CUT Mounting System
The optic is only as good as the mounting solution. The A-CUT is a unique system that acts like a binder of a ski to lock the Aimpoint COA in place. Use code WARHOGG25 to save with Aimpoint.

Where Safariland Fits: Holsters That Support the System
A duty pistol system is only duty-ready if it carries securely, draws clean, and reholsters safely, under stress, with gear on, in real conditions. Safariland offers multiple holster options specifically for the Springfield Echelon line, including COA-ready duty models.
Safariland Echelon Duty Options (Optic-Ready)
Safariland’s Echelon holster page, you’ll see duty-rated options such as:
- 6360RDS / 6360RDSO (ALS/SLS, Duty Rated Level III retention)
- 6390RDS / 6390RDSO (ALS, Duty Rated Level I retention)
The War HOGG Overview Process
When I start the overview of a pistol, I’m looking for early indicators that tell me whether this platform supports performance or creates friction.
Trigger and Presentation
First, I evaluate trigger feel, trigger break, and reset. Then I evaluate the presentation. Does the grip angle and ergonomics allow the dot to show up where it should without extra movement? If I have to make adjustments to find the dot, I note it.
Zero and Accuracy Confirmation
Next, I zero the red dot and confirm with a 25-meter bull shoot. That gives me a baseline accuracy check and confirms the system isn’t doing anything weird mechanically.

War HOGG Self-Eval for Baseline Data
Then I run a performance baseline using the War HOGG self-eval. This is where opinions stop and shooting performance data starts. Do I have any issues with firearms manipulation with this platform? After determining that, I run the skills that matter for duty carry:
- 5-shot drills
- Target indexing
- Strong-hand and support-hand shooting
- Magazine changes, both speed and tactical
- Shooting with gloves
Low-Light Ammo Testing
If you’re law enforcement, low light isn’t a specialty. It’s a major portion of your working life. For this overview, we look at muzzle flash and workability using: Hornady American Gunner 115gr XTP, Hornady Critical Defense 115gr FTX, Hornady Subsonic 147gr XTP, and PMC 115gr training ammo.

We evaluate flash with and without a weapon-mounted light (SureFire X300 pattern) because white light changes what you see, how you track, and how you recover for follow-up shots.
The goal isn’t to crown a “best ammo” winner. The goal is to understand what happens and document it, so decisions are made with information, not assumptions. We do this same evaluation in every War HOGG Tactical low-light course.
Range Performance
I took the Echelon 4.5F COA out to the range, in both daylight and low light, using my weapon-mounted light, running a wide variety of ammo through the pistol with no issues. I focused on Hornady for our duty ammo, both day and low light, Defender 124 grain and PMC 115 and 147 for training ammo, and ICC Ammo for our frangible ammo on steel, using both the 17 and 20 round magazines.
The Echelon was easy to zero and validate the duty ammo, we proofed it with a 96 2x shooting a 25-meter bull slow fire.
From there, I moved into a series of drills to see how the pistol performs, conducting tasks like speed and tac magazine changes. Some pistols will have the mags hang up due to the materials of the pistol and magazine. I had no issues with the Echelon magazines.

I conducted a series of marksmanship fundamental drills, including the War Hog 5-shot drill, to test the grip texture to make sure it was not tearing my hand up.
I then did some draws from my Safariland holster while wearing gloves and had no issues. I finished up with some target indexing drill, shooting a C zone piece of steel and the War HOGG Tactical training Target, and some strong and support hand shooting.
Overall, I had no issues with the Echelon COA on the range and really like the slimness of the grip for a full size pistol.
