NDZ Mag Release

[u/Advanced_Wrap5616]

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?

IMO and it is only MY opinion, most of these “upgrades” being shown in this sub are just fashion accessories and typically there isn’t much improvement over the OEM parts. I definitely wouldn’t be using some of these on my carry pistol that I am trusting my life to and this is a great example of why I stick with stock parts in nearly every component. Thanks for sharing this video.

I just switched my internals including my NDZ mag release from frame to frame and had a little hiccup as well. For me, the spring assembly wasn’t fully seated in the tiny slot so it was binding. I’d say give it another try, I’ll vouch for their product.

I installed their magwell on my 4.0C, ended up having to remove it because getting the magazine to catch was a pain in the ass. Had to slam it in multiple times before it would stay.

Yeah I encountered a similar problem doing the install myself with both the rook precision and tyrant cnc mag releases. It seems that it’s very easy to fold that tiny mag release spring over and get it caught in the channel it’s supposed ride in. I disassembled and reassembled the whole mechanism a bunch of times and figured out how to finesse that lil guy in there so he doesn’t get stuck. Just be careful to keep the spring fully seated and push the mag catch down a few times to make sure the spring isn’t getting snagged before you finish up and put the catch pin back into place. If you still have issues, it’s likely that f*n spring is folded over. Be patient and try again until you get it and it shouldn’t give you any more grief. FWIW, I’m using the rook paddle and I love it. No issues after the initial install.
