Glock 30S issue

[lock n' load]

I recently bought a Glock 30S and have only got to shoot it a couple of times. Yesterday I had issues with the last round get jammed in the gun. The bullet appears to be pointed upwards when viewed from the ejection port on the slide. I had the issue happen 4-5 times in a row. I had recently changed out the stock baseplate with a Pearce grip extension as I was getting pinky pinch with the stock baseplate. I had also installed a #30 o-ring on the magazine that sits on top of the baseplate to also help with the pinching. Next trip to the range I will try the other stock magazine to see if it repeats the problem. I wonder if the o-ring may be the issue? It is the same thickness as the gap left after the magazine is inserted into the gun. I'd read on some other forums where some people used the o-ring/Pearce extension method and it helped with the pinching. Also, the 10-round magazine is downloaded to 9 as it is a Herculean feat to load in the magazine and also rack the slide. I can hear one of the rounds rattling in the magazine but read that it's normal. Anyone on here have the same issue as me?

Sounds like a mag issue, Usually when rounds stick up at that angle it's a feeding issue. switch back to factory mags and I bet you don't have that problem. In my almost 6 years of selling guns we've not had to send a Glock back for repair. I would be surprised if it was the gun.

There actually is a different spring used when installing an extension-

Spring from original mag is a little short for the extension-

I swapped out the Pearce baseplate to the stock one and still notice a rattling sound when loaded with 9 rounds. I noticed that even when empty, the magazine has a slight rattle to it. I then decided to try the Pearce baseplate on the second magazine. I didn't notice any rattle when it was loaded. I'm beginning to think that maybe the magazine has a bad spring? I'll go by my LGS tomorrow and pick up a new spring and see if that may fix the issue.

I have several mags, that rattle when loaded, but they seem to work, however, I always load one round short for night stand, but full at range.
