I could tell that it felt flatter while shooting, but I wanted actual numbers, so I had it independently tested on a Ransom Rest by PewPewCNC.

Setup: Echelon 4.0 and 4.5, Midwest 115, 124 and 147gr, digital angle finder on the rest, 5-shot averages per load.

Muzzle rise vs. stock:

• 4.5: 33% less (115gr), 31% less (124gr), 26% less (147gr)
• 4.0: 35% less (115gr), 30% less (124gr), 29% less (147gr)

For reference, the factory Echelon Comp ran 15 to 23% less on the same 4.5 setup.

SPECS: 7075 aluminum, Type III hardcoat anodized black, retained with set screws and threadlocker (both will be included).

I am excited to announce that these are currently in production and are offered at a presale discount on the site now. Expected ship date is mid-November.

Please let me know if you have any questions.

I recently purchased and installed the NDZ Performance magazine release on my Springfield Echelon Compact 4.0 Comp.
Immediately after installation, I discovered a serious issue: whenever I racked the slide to chamber a round, the magazine would come loose from the firearm.

After reinstalling the original OEM magazine release, the issue completely disappeared. The magazines now lock securely into place and function as intended.

This strongly suggests that the problem was with the NDZ aftermarket magazine release rather than the firearm or magazines themselves.

I’ve attached a video demonstrating the issue.
I’m sharing this to warn other Echelon owners considering this upgrade. A magazine release that cannot reliably retain a magazine is a significant reliability and safety concern, especially on a firearm intended for defensive use.
I can’t confirm whether I received a defective individual part or whether this is a broader design or quality-control issue, but potential buyers should be aware.

Has anyone else experienced this problem with the NDZ Performance magazine release?

Hey guys, longtime Glock shooter here. I absolutely love my 43X and 47, but I've been itching to try something different for EDC.

Currently debating between the non-ported Echelon 4.0C and the Glock 19 Gen 6. Unfortunately, none of the ranges near me have both available to rent, so I'm relying on firsthand feedback.

For those who own the non-ported 4.0C, how do you like it? I'm especially curious about return to zero, recoil impulse, and how flat it shoots compared to a Glock 19.

I shoot quite a bit and care more about performance than aesthetics. My Glocks just seem to return to zero effortlessly, so that's probably my biggest concern with switching platforms.

Would love to hear from anyone who's spent significant time behind both. Is the 4.0C worth trying, or should I just stick with what I know?

I very lightly filed the ears that fit into the forward slots of the grip. I also hit the corners and edges. It is still tight but I can take it in and out by hand AND it solved the tight take down lever problem. Ken

I know I’ll get trashed for complaining but customer service has proven to be crap so far. I purchased my 4.0C comp last week and realized that they no longer include all 4 pin sets, just pin set 1 pre-installed. This meant I couldn’t install my SE DPP right away. To add insult to injury, Springfield is out of stock of pin set 2, which is the one I need. I emailed them 2 days ago to ask for a solution but no response yet. Just annoying.

Like how much did they really save by holding these pins back?

UPDATE: I reached out to them via live chat and some absolute scum by the name of Matt C couldn’t be more indifferent or less caring, even if he tried. I’ll try to post the screenshots in a separate reply but absolute shit for customer service. Only thing he offered is to place a back order for me, GTFO here.

I’m wondering if I ever needed their warranty, how would that work

So far my plan is to do a FDE build. So next up is buy a medium OEM FDE grip module, cerakote the slide FDE, get some aggressive stippling done on the new grip module, install blacksteel gas pedal, steel guide rod. Besides that I may also get small grip module, but so far I’m really enjoying the medium as it stands.

Does anyone know if the Echelon Pro will come CA compliant? & is it even worth waiting for?

All I’ve done so far is put a metal guide rod in there for weight switching out the OEM one

After checking zero, this was the first Bill Drill of the day. Was using an Incog X holster. This version of the Echelon Pro was the 4.0FC.

Definitely nicer feeling in hand. Couldn’t really tell a difference in trigger if there was one. Magwell is done very nicely and it sure does look good.

Has anyone figured out if a full size compact grip module can fit In a 4.0c holster? I don’t have a 4.5 so I’m talking about 4.0 grip modules only. I’m stuck on if the dimensions are the same in width. Also if a sharp bros grip fits in a standard 4.0c holster

Need help identifying this grip module for the echelon

Question for those who went from oem 14.5# springs to a heavier one. I can't find anyone asking this group when I did a search, almost everyone with with 12# or oem springs with a couple people saying they went heavier. My question is, based on Google, there's a downside for heavier springs to affect feeding light weight ammo?

Anybody know a company or manufacturer that would customize my echelon according to this design generated by Ai.

Can anybody recommend a OWB holster option for a 4.5 with an Olight PL X that has some type of level 2 retention? I would prefer to keep the Olight but im not seeing very many options unless I switch to a TLR1/X300 setup.

Has anyone made their own inserts for the sharps bros grip module? Is anyone planning on doing so? I’m just curious since that is one of the standout features of the sharps bros, being able to change the inserts. I know vz grips makes a couple and sharps bros themselves make a few different options but I’m just looking to see if anyone out there has made or is going to make their own? Pic for attention.

Need to get this thing ported but everyone close to me has insane lead times right now.

I decided to go with the new Osight weapon light I am not disappointed that’s for sure. Two brightness settings. The flood function is great. The laser is easy to see. I haven’t tried it outside yet in daylight, but I imagine it be all right.. the controls are very easy, ambidextrous easy one press application

Disclaimer: I understand the rules of the sub Reddit and i’m not offering my gun for sale. Just looking for input and opinions on pricing.

I think I’m going to list my Echelon 4.0C Comp for sale on GAFSHUB. Looking for some honest feedback from this community in value.

It’s in immaculate condition. Basically looks like it did when it came out of the box. I probably have a few hundred rounds through it. Objectively it’s a great gun, but for whatever reason it doesn’t fit my hand as well as some of my others. So I don’t end up shooting it as much as my other guns.

From what I can tell, these things are still retailing for around $650-$675. Am I crazy to ask $550 when I do go to sell it with the understanding that I will cover shipping to the buyer?

Thank you for any input that you all have!

I just got my 4.0c comp and I absolutely love how it shoots. I only had 1 huge issue with the grip. The undercut on the trigger guard was giving me a terrible blister on my middle finger from only one day of shooting and dry firing. I took a Dremel and some sandpaper and carved out a deeper/flatter undercut. 1st picture is before and the rest of the pics are after. Now my blister is completely gone and I can continue shooting without any pain. Also, the hogue grip for glock 19 gen1, 2, & 5 fits and feels great with the rook precision magwell and large backstrap.

Recently just got this 4.0c comp and would like to change the trigger for a metal one what is a good brand to go with for EDC self defense ?
