I have read about owners having problems with the ambidextrous magazine release on G21SF pistols. I have fired approximately 500 rounds through mine and I haven't experienced a problem as yet.

I want to round off my trigger guard (just because) but I'm worried that soon after, the mag-release will fall out and my warranty will be voided because of the alteration.

I was wondering if I should just send it back to Glock now and ask for the updated one-sided magazine release. Opinions?

Is this the same mag release that comes in the new 4th generations Glocks that you're talking about?
