My G30SF would not chamber the 230 gr GDHP when hand fed last night.It's always fed anything I've put through it to include the Federal HST and Ranger T ammo. I wanted to check it out before going to the range Friday and 2 out of 3 times it would just go about 1/3rd the way into the chamber. Very odd for a Glock and especially since this one has never had any of the FTRTB issues some have had. I don't know what happened but the problems seems to be the magazine which looks pretty rough. There's only been maybe 50-75 rounds through that mag. The polymer has separated from the metal feed lips on both sides and I feel sure this is what caused the malfunction. The ejector is not dragging on the slide as there are no scratches.

I was going to post some pics but the forum wouldn't let me. Seems you have to have five post before you can add attachments, which would have told the story well. The mag just looks beat up around the top. It's hard to describe without pics.

Interesting. Would the same mag feed any other type of ammo?

Regardless, always remember magazines are expendable. I would suggest if it looks that bad and appears to be causing issues send it back to GLOCK under warranty. They'll replace it.

It will feed most all including the GDHP but you may get two failures one right after another and then next may feed. I did write Glock and sent them two shots-one of the jam and another of the magazine. Hopefully they'll respond in a few days. Again, though, that magazine has seen little use.

It wasn't your usual bolt over base type of malfunction. The extractor had picked up the rim of the case and was guiding it in the chamber but the round stopped short of entering it. Only about 1/3rd of the round made it into the chamber. The FMJ responded like the GDHP ammo did. sometimes it would go in and other times not.

Maybe these photos will work now.

This is what the jam looked like- a simple FTRTB issue.


This is the offending mag. There is just no reason it should look like this.

What the heck happened to that mag?

I wish I knew. I never noticed it last time I shot it(about three months back) as there was no problems with the FMJ and Ranger T ammo I shot then. It was only after I tried to hand feed a few 230 gr GDHP's that I noticed it last night. It didn't look too bad until I took the photo with a macro lens and then you could really see just how bad it was. I can't imagine what caused it. It looks like it had 500,000 rounds through it.

I might add that I tried the same ammo hand fed with another magazine and it slipped into the chamber like butter.

You've used the term "hand fed" a few times in this thread. Describe exactly what you mean please.

If you are riding the slide forward to chamber a round rather than letting it slingshot or rather than just dropping the slide by pressing the slide stop lever I can see why some specific ammo with gaping hollow points might not feed well.

I pull the slide back and let it go. Nope, I don't' ride the slide. I've made that mistake ears ago. I just put a couple of rounds in the magazine, pop it in and full the slide back.
