Common ETS Glock Magazine Problems and Solutions

Jamming ProblemsClean magazine, troubleshoot.
FTF with Specific AmmoUse the suggested ammo.
Tight Mag WellUse in the guns that fit it properly.
Feed Lips ProblemChange the style of inserting or replacing ETS.
Not Dropping FreeTroubleshoot or use proper gun model.

1. Jamming Problems

In the ETS 40-rounders, a jam on the final two rounds is rather typical.

Possible Reasons

The 40-round mags will do that when they get dirty.

The Fix

They should be scrubbed with soapy water and a brush, dried, and then coated with silicone spray.

They function normally once more for around 800 rounds.

Cutting a nub off the follower may resolve the problem if cleaning doesn’t work. But this may invite other problems when done incorrectly.

2. FTF with Specific Ammo

There would be failures to feed about 30% of the time when using steel ammo. 

Possible Reasons

The steel-cased WIN ammunition is the most problematic. Aluminum and steel are prohibited in ETS magazines. Even the Federal HST 9mm nickel plated cases are disliked by the ETS.

Feeding issues are brought on by being slightly (or significantly) underpowered and the case’s texture.

This is true for both their pistol and rifle magazines, and it is not in the least bit ETS’ fault.

Essentially any plastic magazine without an interior metal sleeve and feed lips will have the same issue.

The Fix

Try with brass ammo, see if that helps. Putting some dry lube on the spring and inside of the body can eliminate 99% of these issues.

3. Tight Mag Well

It requires considerable force to remove an ETS magazine after it has been inserted. with a Springfield Saint, BCM, etc., in particular.

Possible Reasons

It requires considerable force to remove an ETS magazine after it has been inserted. More so, with a Springfield Saint, BCM, etc., in particular.

The Fix

The only thing to do here would be to replace the ETS magazine. I would suggest Magpul as it performs really well with the mentioned guns as well as Glock!

4. Feed Lips Problem

The Glock 43 would not correctly feed ETS magazines. Stovepipes would develop on a regular basis.

Possible Reasons

The feed lips are really particular. It does not feed a lot of ammo to some extent.

Before any other cartridges could slip on, a tiny bit of play where the cartridges sit would cause a jam.

Furthermore, you cannot feed at all even if the lips are slightly out of alignment!

The Fix

Learn how to properly feed the gun. Use proper ammo (do not use brass). If the issue doesn’t resolve, the only thing to do would be to replace the magazine.

5. Not Dropping Free

The 22-round ETS magazines frequently fail to drop free. Particularly on a firearm like the Glock 19 Gen 4.

Otherwise, a flick of the gun will still be able to release some if they hang up a little time-to-time.

Possible Reasons

Clearly, the magazines are the issue and not the weapons. The prolonged mag release could potentially be the cause.

If you had this in a hot location, the mag well may have distorted with time.

The Fix

Check out the release after uninstalling it. To see if the release is dragging or holding the magazine in and preventing it from dropping free, you can try peeking through the mag well first.

Additionally, the ETS magazines differ slightly from Glock magazines. Some of my guns fit them better than others. For instance, they are too tight to operate in the G17-based Sub 2000.

So, if it is a nuance to your gun, please replace it!

User Feedback on ETS Glock Magazine

Some people had problems with the mags. Locking issues, springs that stick, and other issues. Others thought they were all excellent.

From what it seems, they are more unreliable in some Glock models than others. Usually in the Glock 17, they may cause trouble. Usually, all failures can be traced back to the springs.

Usually, the 7-rounder would insert without a problem. But it would never successfully feed the first round of the magazine while firing. This is a common issue.

However, you won’t find OEM magazines anywhere else for less money. Keep in mind that ETS also offers excellent customer service! Customers value this a lot.

Although loading all 15 rounds into the magazine might occasionally be tricky, if done correctly, you won’t experience any feeding troubles. In my opinion, it is a reliable source to get OEM mags.

Frequently Asked Questions (FAQs)

What is the highest capacity Glock magazine?



I would say, never trust your life with anything but a Glock factory magazine. However, if you really want aftermarket mags, the ETS indeed is a good choice.

But for more sophisticated use, buy something like Magpul. There are issues like hurting your finger due to a sharp edge where the rounds insert into the magazines.

It’s unfortunate that they won’t fit in the mag well of the Ruger Carbine. Additionally, it could be difficult or impossible to fill the indicated capacity due to the feed lips.

The color inserts and base plates can be an issue too. In my opinion, look for better aftermarket OEM mags if your budget is not a problem.
