Absolutely not.

Well, that makes me feel better. I'll dry everything off and only put a tiny bit of lube everywhere the manual says and see how that works. I'm really hoping the new spring will solve the issue.

I was very surprised to learn that Glock recommends very little lubricant and only in certain places.


Over lubricating a freshly cleaned Glock will not cause it to malfunction unless something else is wrong with the pistol.

Of the symptoms you mentioned/observed, both point toward weak recoil spring.

Failure to feed sounds like a weak recoil spring.Failure to go into battery is almost always a weak recoil spring. (Caveat: Assuming the gun is clean and properly lubed).

There is a simple test to see if your recoil spring is too weak:

a. With an EMPTY gun, pull the slide to the rear, and then EASE it forward while holding the gun horizontal. The slide should move fully into battery on its own.

b. Same test but hold the pistol with the barrel pointing straight up. EASE the slide forward and see if it will go into battery without any assistance from you.

In the future you'll want to do these tests to decide when it's time for a new guide rod/recoil spring. (Glock used to recommend changing the spring every 5000 rounds.) If the spring passes test "a" but fails test "b", you're getting close to needing to order a new guide rod. If it fails both tests, you definitely need a guide rod.


Disclaimer: I am not a Glock armorer. But I have fired approx. 200k rounds through Glocks over the years.

Thank you for this! I'll try it out tonight and report back.

You are right. I am certain that the engineers who designed the pistol didn’t have a clue what they are doing. My advice to someone who is having issues with a mechanical device is always to disregard the manufacturers instructions and do whatever they feel or have heard is best.

OR... despite common sense and people on the internet. When having trouble, one may disregard other thoughts and follow the manufacturers instructions to the letter and determine if that helps the situation. Especially since, once you make the time and effort to contact the manufacturer, this is the first thing they will tell you to do.

I didn’t say I thought over lubrication was the issue. I said I have heard it was possible. What I also said was that I was surprised at their instructions and maybe he should try that just to rule it out.

So follow-up, I tried letting it ease into battery last night from both horizontal and straight up positions. The slide definitely went forward all the way each time, though there was a slight "catch" right before the last maybe quarter inch. I suspect that is normal, but not sure. Any thoughts?

New spring arrives today, so I'll try it out with that one and see if I notice anything different.

Side note: I just tried this test with my Walther PPS M2 and it seems to have a much stronger pull into battery than the Glock. So I'll switch the spring tonight and see if there is a discernable difference.

Replaced the spring. Send to have a stronger pull forward into battery, so maybe that was it. The “catch” right before it goes fully forward is less pronounced.

I did notice that the new spring, the actual spring itself, has a gold-ish patina to it whereas the original had a very dry, almost galvanized steel look to it. Physically, they both look the same other than that really pronounced color difference. Anyone know if this means anything?

Update on this:

Took the G26 out this afternoon to test the new recoil spring and all was good. Shot 150+ rounds with zero FTFs or anything else. My 12-year-old shot a good number of those and he experienced no problems, either. So, Glock fans can breathe a sigh. It was a bad factory recoil spring, but an easy fix.
