Springfield’s Grip Modules for the Echelon 4.0C

When Springfield Armory released the Echelon 4.0C, I was an early adopter. The original Echelon 4.5F had impressed me, and I was wanting a more compact version with all the same features. The 4.0C was all of that and more.

The Springfield Echelon 4.0C grips come in three different sizes to fit a variety of hand shapes. Each grip module ships with its own color-matched backstraps for additional customization.

I say “more” because the shorter slide assembly made the gun perfectly balanced in my hand. I hadn’t expected that the gun would be better balanced in my hands as the full-sized pistol felt great. Nevertheless, the 4.0C is now my preferred duty-style pistol.

Like the 4.5F, Springfield Armory built the 4.0C around a modular system that allows you to tailor the pistol to your hands using grip modules.

What Is the Springfield Echelon 4.0C Grip Module?

The Echelon 4.0C grip module is the polymer portion of the gun that you hold when shooting the pistol. It houses the Central Operating Group that contains the trigger assembly and other fire control components.

The image displays a Springfield Armory Echelon 4.0C grip module with the Central Operating Group fully installed. The grip module is made from textured black polymer, and the Central Operating Group — visible through the module’s openings — houses the trigger assembly and other key fire control components. This setup demonstrates how the serialized receiver (Central Operating Group) is completely separate from the grip frame, making the firearm modular and highly customizable. The installed module includes a magazine release and cutouts for the slide stop lever, all visible in the image. The photograph is well-lit, highlighting the clean fit and alignment between the grip module and the Central Operating Group. The background is plain, making the gun parts the focus of the shot. This picture is ideal for showing how the Echelon 4.0C’s modular construction sets it apart from traditional pistol designs. — An OD green Springfield Echelon 4.0C grip module shown here with a Central Operating Group ready to be installed.

A lot of people refer to the grip module as the frame of the gun. But that’s not, in my opinion, the most accurate description. Gun frames are often interpreted to mean the receiver. For most handguns, that is the grip portion of the pistol as the fire control components are integral to it. That is not the case with the Echelon.

Echelon pistols use the aforementioned separate Central Operating Group, which is not part of the grip module. It is the Central Operating Group that is the serialized receiver, or the legally defined part that is the “firearm”. While the Central Operating Group rides in the grip module, it is distinctly a separate entity.

Since the Central Operating Group is not part of the grip module, the grip modules are not controlled by the Gun Control Act of 1968. This allows you to buy grip modules just like you would custom walnut grips for your 1911. They can ship right to your door.

Three color options for the Springfield Echelon 4.0C grip modules: OD Green, Desert FDE and black. These factory-made grips let users match their firearm to their personal style or operational needs.

Just like 1911 grips or revolver stocks, Echelon grip modules allow you to custom fit the gun to your hand for improved accuracy. Additionally, they give you color options.

The Echelon 4.0C grip module is specifically cut down in size compared to the full-size 4.5F. It keeps the same internal dimensions, but the grip length is shorter to better suit concealed carry or smaller hands.

Three Sizes: Small, Medium, and Large

Springfield Armory makes the 4.0C grip frame in three sizes: small, medium and large. These sizes refer to the total gripping area of the modules. In general, the larger your hands, the larger the module you might like.

The image shows several Springfield Echelon 4.0C grip modules each paired with three removable, color-matched backstraps. The grip modules and their backstraps are arranged by size or color, allowing a clear view of how each backstrap matches its corresponding module. The photo highlights the textured surface and ergonomic shaping of both the grip modules and backstraps, designed to enhance comfort and control. The modules are displayed in various colors — black, OD green, and Desert FDE — with each backstrap perfectly matching the polymer finish. This setup demonstrates the level of customization available, as shooters can mix and match different backstrap sizes for a personalized fit. The background is plain, focusing attention on the components themselves. This image helps illustrate how the Echelon’s modular design extends beyond just the main grip frame to include multiple backstrap options. — The Echelon’s grip modules feature backstraps in matching finishes. Adjusting the backstrap lets you dial in the most comfortable grip for your hand.

All of the Echelon 4.0C modules ship with a magazine release pre-installed, so there is no fiddly work needed. If you can field strip the Echelon pistol, you can easily install one of the new factory modules.

Each grip module from Springfield Armory includes three color-matched backstraps to fine-tune the fit even further. Three module sizes with three differently sized backstraps give you a significant amount of customization to find the best fit for your hand.

Typically, I like thinner pistols, so I was surprised to find that the large module worked best for me. With the medium backstrap, the large grip module gave me a consistent, natural point.

Of course, everyone is different. I had a buddy with smaller hands try the small, and he immediately found better control and less shifting under recoil.

Grip Colors: Black, FDE, and OD Green

In addition to sizing, you can choose one of three colors for your Echelon 4.0C grip module. Currently, Springfield Armory is offering Desert FDE (Flat Dark Earth) and OD Green (Olive Drab) in addition to the standard black. The finish is molded-in polymer, not paint or Cerakote, so you don’t get weird wear patterns over time.

The Echelon 4.0C grip modules are available in classic black, subtle OD green, and standout Desert FDE. Choose a finish that matches your preference or gear.

Black is classic, of course. It matches most holsters and goes unnoticed in professional settings. If you are carrying for a job — police or security — black is likely the way to go.

Desert FDE and OD Green modules are driven by your specific tastes. These color options help you build out a platform that doesn’t look like every other handgun at the shooting range. To my eye, the OD Green is a subtle variation from black, while Desert FDE is an obvious color change. I think both colors are well executed and attractive.

Who Needs a Grip Module Like This?

Anyone serious about concealed carry, duty use or just enjoyable range days with the Echelon 4.0C should at least try the different grip modules. Getting the perfect hand fit with your gun can bolster your shooting and confidence.

The modules are polymer and come in different sizes to accommodate various hand shapes and preferences. The focus is on the hands and grip modules, highlighting the process of finding a proper ergonomic match. The workspace is well-lit and organized, with additional grip modules visible on the table. This image demonstrates the practical, hands-on approach to selecting a grip module, which can improve both comfort and shooting accuracy. It’s a useful reference for anyone considering an upgrade or customization to their Echelon 4.0C. — Proper fit makes a noticeable difference in handling. Testing multiple grip module sizes helps ensure you find the most natural and stable option.

If you’re sticking with the factory configuration, you could be leaving some accuracy and precision on the table. Sizing isn’t cosmetic; it can be a functional improvement in your shooting.

Of course, color options are always a nice way to express a bit of individuality. And there is nothing wrong with buying another color just because you want to.

Tips to Installing the Springfield Grip Modules

Swapping grip modules on the Echelon line of handguns is a simple and straightforward operation. Nevertheless, I learned a few small tricks that make the process even easier. Try these steps and tips:

1. Unload and clear the gun. Remove all ammunition from the area.

2. Field strip the pistol according to Springfield Armory’s instructions. Once the slide is removed, you can begin the process of changing modules.

The image shows a Springfield Armory Echelon 4.0C pistol in the early stages of field stripping, with the slide removed and laid to the side of the frame. The grip module, frame, and exposed Central Operating Group are visible, illustrating the process needed before swapping grip modules. The work area is clean and well-lit, emphasizing the importance of safety and order during disassembly. The pistol is clearly unloaded, with no magazine or ammunition present. This photo highlights that removing the slide is a necessary step before accessing the Central Operating Group and changing the grip module. The setup is straightforward and follows Springfield’s recommended procedure for modular changes. This image is useful for anyone unfamiliar with the field stripping process for the Echelon 4.0C. — After clearing the gun, field stripping the Echelon 4.0C is the first step to changing the grip module. Rotate the takedown lever and remove the slide assembly.

3. On the right side of the gun, push the flat end of the disassembly lever in. You don’t have to push it very far in — just enough so your fingers can get a grip on the lever on the left side of the module. You can use your finger or a non-marring tool to push it in.

The image shows a close-up of a person using their finger to push in the flat end of the disassembly lever on the right side of a Springfield Echelon 4.0C pistol. The gun is partially disassembled, with the slide removed, and the focus is on the disassembly lever just above the trigger area. The person’s hand is positioned to apply gentle pressure, as recommended in the user manual. The background is neutral and uncluttered, making it easy to see the location and movement of the lever. This step is necessary to free the disassembly lever so it can be pulled from the left side of the grip module. The photo highlights that no special tools are needed — just a finger or non-marring tool. It’s a clear demonstration of the first step in removing the Central Operating Group for a grip swap. — Use your finger or a non-marring tool to press the disassembly lever from the right side of the Echelon 4.0C.

4. A slight pulling pressure on the disassembly lever will free it from the right side of the Central Operating Group. Pull the disassembly lever so that the end is now in contact with the left side of the Central Operating Group.

5. Pull and twist the disassembly lever in a clockwise motion. Some force is necessary. As you twist, the disassembly lever will work free of the Central Operating Group and you can remove the disassembly lever completely. Set it to the side.

The image shows a close-up of a hand pulling the disassembly lever out from the left side of a Springfield Echelon 4.0C grip module. The hand is using a firm grip and is in the process of twisting the lever in a clockwise direction, as recommended by Springfield’s instructions. The slide has already been removed, and the area around the lever is clearly visible. This motion releases the disassembly lever from the Central Operating Group, allowing for removal or replacement of the grip module. The photo demonstrates the resistance that might be felt, which is normal and ensures the components are secure during use. The workspace is neat, with good lighting to show all mechanical details of the process. The image is a practical reference for anyone learning how to disassemble or modify the Echelon 4.0C. — The disassembly lever should be pulled and twisted from the left side to separate it from the grip module. Some resistance is normal during this step.

6. Lift up on the slide stop lever and push the Central Operating Group toward the front of the grip module. If you have never removed the Central Operating Group before, it may be a little tight in the module. This is normal. You can use a wooden dowel or other non-marring tool to push the Central Operating Group forward. It will not need to move very far forward — I’d estimate less than 1/8” — and it will be obvious when you have moved it.

7. Lift the rear of the Central Operating Group while also pressing lightly on the trigger. The Central Operating Group will pivot on the front end, and you will be able to lift the assembly out of the grip module.

The image shows a hand lifting the rear portion of the Central Operating Group up and out of the Springfield Echelon 4.0C grip module. The front end of the assembly remains slightly hooked into the grip, while the rear is elevated, demonstrating the pivoting motion required for removal. The person’s other hand is gently pressing the trigger to help release the assembly, as recommended in Springfield’s instructions. The slide has been removed and the grip module is stabilized on a clean surface. This clear view shows how the Central Operating Group separates from the non-serialized polymer grip, emphasizing the modular design of the Echelon series. Good lighting highlights the mechanical parts and the careful technique used. This image is especially helpful for users learning to perform maintenance or swap grip modules on the Echelon 4.0C. — Carefully lift the rear of the Central Operating Group while pressing lightly on the trigger. This allows the assembly to pivot up and out of the grip module for easy removal.

Installing the Central Operating Group in a new grip module is just a reversal of the removal process. However, there are a couple of tips that can help make the process a little quicker.

First, remember that the forward end of the Central Operating Group “hooks” into the module, which is why it pivots when you removed it from the old module. Ensure that the front end is properly seated prior to trying to slide the rest of it into the grip module.

The image shows a shooter at an outdoor range test firing a Springfield Armory Echelon 4.0C with a recently swapped grip module. The hands are firmly gripping the pistol, and the shooter is in a proper stance with the firearm aimed downrange. The focus is on the grip area, highlighting the new grip module — its texture, color, and fit against the shooter’s hand are clearly visible. Expended shell casings may be seen in the air, indicating live fire. The background is a typical shooting range setting, with targets visible downrange and proper safety gear worn by the shooter. The image illustrates the importance of testing your firearm after making any changes, especially to the grip. It also demonstrates how grip swaps can impact handling and recoil management on the Echelon 4.0C. — After installing a new grip module, always test fire your Echelon 4.0C to confirm proper function and feel. Small changes in grip size or texture can noticeably affect control and accuracy.

Second, when you do have the Central Operating Group seated into the grip module, be sure to slide it to the rear to lock it into place. You can look through the disassembly lever holes on the grip module to ensure the Central Operating Group is correctly in position. If the holes are obstructed, the Central Operating Group is not seated properly.

Finally, when reinserting the disassembly lever, press while rotating in a clockwise motion. Keep pressing while rotating, and the lever will slip through fairly quickly. Once you do it a few times, you should get the feel for it.

Final Thoughts

When it made the Echelon pistols, Springfield Armory rethought the way it could serve shooters of all hand sizes and needs. With three grip module sizes, three included backstraps with each, and three color options, you get a ton of flexibility. That kind of modularity is rare — especially with it all being factory parts with zero gunsmithing needed.

Whether you’re trying to fine-tune recoil control or just find something that feels better in the hand or matches your outfit, checking out the Springfield Armory grip modules is a smart place to start. And in my experience? It works.
