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