GLOCK question

[Echidin]

To echo what others have said, there's no need to slam the magazine in with the slide locked back. The magazine will click into place without much force. I agree replace your slide stop as well.

Quit bruising your plastic.
What are ya Chuck Norris?
It's a month old gun, don't replace your anything.

Not a issue
As others have said, when you slam a full magazine in hard it can release slide stop
Happens on my Glocks and HK's

As you see, some people like the unintended 'feature' and some think it's a defect and most say you can make it happen with a lot of guns. All are correct.

IMHO not worth the hassle of sending the gun back. If you don't like it, don't slam the mags so hard.
