Question Glock feeding problem....UPDATE Solution found

Update... 5/15/2017 =================================
After replacing the recoil spring, magazine spring, polishing the feed ramp, and installing a Wolf gun springs service pack (plunger spring, striker spring, ejector spring and trigger spring) it turns out that issue with the slide locking open after the first 3 rounds was caused by a weak slide stop spring which I promptly replaced with a new factory slide stop. It took serveral trips to the range to narrow it down. I basically have a tuned up Glock 27 now.
************************************************** *******


Good day Fellow Sig Shooters-

I have a first edition Glock 27 I purchased in 1998. Must of put over 7k rounds through it at this point.

The recoil spring was changed about 500 rounds ago to a Wolff setup. I hold it the same way, lube it the same way and basically use the
same hardball ammo for the range. I am now starting to experience a feeding issue where the round will only go half way up the feeding ramp. It
usually happens on the first 2-3 rounds off the top of magazine and I can pull back on the slide a bit and it will load the stuck round into the chamber.

I changed the magazine spring on this particular mag and tried a different mag and have the same issue with both mags.

Could it possibly be ejector related?
Any ideas would be much appreciated?

Thank you in advance!

Clean up your feed ramp, check for dings or scratches. A good quick polishing goes a long way. Make sure you got the correct recoil spring, and it's not damaged. Check your magazine lips, make sure nothing is bent. If you can try a new magazine in it. I doubt it's the ejector, that would be a FTE not FTF. Give it a good clean and see what happens.

If all else fails, sell it and buy a Sig

My first guess would be that it is the recoil spring. You may want to get a factory Glock spring and see if that clears it up. Cleaning and polishing the feed ramp certainly won't hurt, but it sounds more like it is a spring issue. I had a Gen 1 Glock 17 that had I don't know how many thousands of rounds through it. I replaced the spring with another factory Glock spring and it ran like a top.

I believe it will be recoil spring related. If the top 2-3 rounds are having difficulty, it is where the round stack is under the most pressure. It sounds as if your Wolff setup needs a little stronger spring, since the one you installed lasted only 500 rounds. Not being familiar with spring rates in Glocks, I'd hazard a guess you may need to go about 2# stronger.
I seriously doubt the extractor would have any effect on chambering, unless the cartridge encounters a problem sliding up under it with the extractor groove. Removing the slide and barrel will allow you to manually try sliding a cartridge up the breechface, from below. If there is no problems doing it, then I would look at a stronger recoil spring.

I ruled out mags. I actually tried a 15 rounder - the first time this happened - and that's relatively new; and had the issue as well. But feed ramp issues... didn't think to look that over. Thanks! Will do. I guess I need to get the dremel tool and flitz out and work on polishing the ramp while inspecting it.

Sounds like the problems the 224 had for a while, the extractor was either to tight or had the old design. Obviously this isn't the case with your gun but maybe it's dirty to the point it's hanging up. It may not be able to travel all the way causing excessive force required to fully close the slide. Maybe just a detailed cleaning is in order?

Interesting on the recoil spring comments as the possible problem. The Wolff is not that old and I always considered them top notch. I could be wrong (not the first time). Sounds like I may want to replace it with a factory recoil spring as well. Thanks

I would consider Wolff to be top notch still, you may have just gotten one of the very rare bad springs. Happens to any manufacturing company.

Factory recoil springs are inexpensive so get one and see if it solves the problem. If it doesn't fix it then start looking elsewhere.

I just looked over the feed ramp etc and cleaned inside the ejector area, etc... and it looks fine and areas clean. I am going to start by replacing the Wolff spring with a factory recoil spring like was suggested. Although I must say I ruled that out first because its not that old. Hopefully its that easy because I am quite fond of this gun. Thanks again!

Another recoil spring vote here.

I will also add that the striker spring plays a part in the way the slide functions as well. For lack of a better description, the striker spring puts rearward tension on the slide once the striker engages the trigger bar. While this likely isn't causing your issue it might be worth pulling the striker and making sure everything is okay in there. Check the striker channel liner as well and make sure it is still in place and isn't damaged.

You mentioned Wolff setup, if by Wolff setup did you change out the barrel as well? Personally I doubt its the spring, not saying it couldn't be but typically I usually don't see malfunctions like that in a Glock unless the barrel has been replaced with an aftermarket. Sometimes the aftermarket feed ramps can cause problem. Just curious.

"Wolff setup" meaning the inner and outer wolff recoil springs and a wolff guide rod. I use the original Glock factory barrel. I plan to install an OEM recoil spring and test the same mags. If it works - its the wolff recoil spring that is the issue. If it doesn't, I move on down the line by replacing the internal springs (ejector, plunger, striker) from the Wolff service pak.
